National Capability - Polar Expertise Supporting UK Research
Lead Research Organisation:
British Antarctic Survey
Department Name: Science Programmes
Abstract
The British Antarctic Survey (BAS) is NERC's world-leading hub for polar science, addressing issues of key global importance and helping society adapt to a changing world. Using funding from a variety of sources, BAS delivers science programmes across a range of disciplines, always focussing on globally significant questions, and always on solutions. BAS science looks to the polar regions and beyond to understand the Earth System, in the past, present and in the future, and the influence of and impact on society.
Under National Capability Science Single Centre (NCSS) funding NERC's British Antarctic Survey will deliver a portfolio of underpinning activities that will provide a backbone for UK environmental science. This will include four portfolios of Sustained Observation focused on crucial Earth System indicators in Antarctica and the Southern Ocean. It will also ensure the availability of four Key Capabilities (instruments, facilities and expertise) that are unique to BAS, and are of prime underpinning importance to the future success of UK science.
Sustained Observations:
SO1 - Rothera Time Series (RaTS) - An integrated suite of oceanographic and biochemistry variables (e.g. temperature, salinity, macronutrients, chlorophyll) collected at a key site of rapid climate warming and high inter-annual variability on the Antarctic Peninsula. These data sustain a wide range of research by UK and international collaborators.
SO2 - Scotia Sea Open-Ocean Biological laboratories (SCOOBIES) - Measurements of the uptake and sequestration carbon dioxide by the ocean within the largest hotspot of primary productivity in the Southern Ocean. These data provide key information on the potential for the ocean to absorb and lock up human emissions of carbon dioxide, and will inform major NERC and international programmes on biogeochemical cycles, climate change, ocean acidification, and micro-plastics transport.
SO3 - Ocean Forcing of Ice-sheet Change (OFIC) - In situ measurement of ocean-heat delivery to the most rapidly-retreating parts of the Antarctic ice sheet using oceanographic moorings and bespoke radar systems. This unique dataset records changes in the major driver of Antarctic ice-loss, informing ice-sheet and global sea-level projections.
SO4 - Space Weather Observatory (SWO) - Year-round observation of space weather events acquired at key sites (e.g. Halley VI Research Station) improve our understanding of the complex chain of Sun-to-Earth processes. They underpin assessment of the likely impact of severe space weather events and the design of mitigation guidelines.
Key Capabilities:
KC1 - Ice-core acquisition and analysis - the unique resources provided by BAS provides UK researcher, and their international collaborators with the ability to recover and analyse ice cores (up to 1000 m). We will provide ice core drills for deployment around the world, and state-of-the-art laboratories in Cambridge capable of a wide range of climatologically and environmentally-relevant chemical, gas, and stable isotope analyses.
KC2 Sub-glacial access and sampling - BAS leads the world in hot-water drilling through ice. We will provide the hardware and expertise to access subglacial environments around the world, and the ocean cavity and seabed beneath ice shelves in the polar regions. In addition, we provide a suite of borehole sensors and cameras, water-sampling, and down-hole sediment corers.
KC3 Airborne geophysics - BAS will deliver an airborne geophysical capability deployed on low-cost piloted and autonomous aircraft. This instrument suite includes gravimeter, magnetometers, and ice-penetrating radar, which can be flown with LIDAR in support.
KC4 Airborne meteorological and atmospheric instrument suite (MASIN) - BAS will deliver an instrumented aircraft with suite of atmospheric instruments and scientific expertise ready-to-support grants, collaborations, and strategic programmes.

Planned Impact
As required for National Capability (NC) research, the NC activities offered in this proposal will provide crucial support to the UK and international research communities, underpinning existing programmes, grants, fellowships studentships and supporting future activities.
Each portfolio of Sustained Observations provides long-term measurement in a critical area of global science, quantifying changes in polar processes that have far-reaching consequences. Ultimately, our observations will inform policy-makers, and society at large, providing for evidenced-based policies:
- Managing our response to climate change (for example, by working in partnership to improve the models used for projection of regional climate, sea-level, and carbon-flux).
- Allowing society to benefit from natural resources (for example, supporting the international fishing industry and providing advice directly to the relevant regulatory bodies).
- Improving resilience to natural hazards (for example, by understanding the risk of severe space weather events to satellites, and terrestrial infrastructure).
Each portfolio, and the programmes they underpin will directly benefit the UK research community, providing high-quality time series that provide insight over natural cycles such as El Niño / Southern Oscillation (ENSO) and the 11-year Solar Cycle, allowing quantification of natural variability and emerging trends, data against which models can be tested, and improving understanding of the key processes. Ultimately, each portfolio will inform assessments of the Intergovernmental Panel on Climate Change (IPCC) and the UN Framework Convention on Climate Change, and the decisions of the Scientific Committee on Antarctic Research, and the 53 signatory nations of the Antarctic Treaty.
In addition:
SO1 - Rothera Time Series - (RaTS) will provide observations of the impacts of high-latitude climate change, within the US Palmer Long-Term Ecological Research programme.
SO2 - Scotia Sea Open-Ocean Biological laboratories (SCOOBIES) will provide advice and data to the international agreement by which the Commission on Conservation of Antarctic Marine Living Resources (CCAMLR) governs and manages the international fishing industry in the Southern Ocean.
SO3 - Ocean Forcing of Ice-sheet Change (OFIC) will provide crucial data to alleviate the major source of uncertainty in projections of future sea-level rise caused by ice loss from Antarctica, which are largely a result of changes in ocean circulation. Improving predictions of future sea-level rise will directly inform national governmental adaptation strategies, local sea-defence planning, and decisions on investment in capital assets in coastal regions around the world. This will be achieved through international assessments (e.g. IPCC), UK adaptation planning (e.g. UK Climate Impact Programme, such as UKCP18 and the Environment Agency's H++ planning scenarios).
SO4 - Space Weather Observatory (SWO) will provide advice to the satellite and power transmission companies seeking to protect their assets, and the relevant insurance industries. It will address a key risk that includes geomagnetic storms, radiation storms and solar flares, which appears on the UK National Risk Register of Civil Emergencies, owned by UK Cabinet Office.
The Key Capabilities we seek funding for under NCSS support a wide research community seeking to answer key global questions. They provide a concentration of scientific and technical expertise that does not exist elsewhere the UK. We will maintain and develop these capabilities so that they continue to be recognised as world-leading, enhancing the reputation of UK research, and promoting international scientific collaboration, and public and commercial innovation.
Finally, the accessible body of expertise we provide will facilitate the entry of new researchers into NERC science and maintain and further develop an already world-class research community.

| Title | Sounds of Space |
| Description | Using a Very Low Frequency receiver at Halley Research Station we can pick up radio waves made by our planet. We use these waves to help us understand the science of space weather storms. We can also directly convert them into audible sounds and are exploiting these amazing natural 'sounds of space' in a number of collaborations. Update in 2020 - Activity has continued on the 'Sounds of Space' artists project. Recent work has been undertaken to develop a performance for the next large event, due to be at the Welsh Eisteddfod in August 2020. |

| Impact | 'Sounds of Space' Performance Nigel Meredith has been working with artist-engineer Diana Scarborough to find novel ways of visualising space weather data. The 'sounds of space' formed the starting point of this exciting venture and inspired Diana to create soundscapes by combining the mesmerising sounds with original visual sequences. We have since engaged with leading Australian composer Kim Cunio and professional dancer Becky Byers to develop the works into a multidisciplinary show. Our first show, which included a scientific presentation, followed by a performance with animation, contemporary dance and soundscapes, was performed at the Cambridge Science Festival in March. Our second show, which included live music for the first time, was recently performed at the British Antarctic Survey Aurora Innovation Centre and also live-streamed. |

| Description | SCOOBIES scientists highlighted, for the first time, how important Antarctic krill may be for carbon storage on a global scale. Currently, this process is not well represented in many global climate models, so the next steps are to test how including krill affects our estimates of ocean carbon storage. The study, by Belcher et al (2019), estimated a seasonal krill FP export flux of 0.039 GT C across the Southern Ocean marginal ice zone, corresponding to 17-61% (mean 35%) of current satellite-derived export estimates for this zone. These values are conservative estimates of the true flux and highlight the important role of large, swarming macrozooplankton in POC export and, the need to incorporate such processes more mechanistically to improve model projections The SCOOBIES programme has revealed how pteropods, pelagic species that are threatened by ocean acidification, drive the strength of carbonate counter pump (CCP) in a Southern Ocean region that is key for atmospheric CO2 drawdown (Manno et al. 2018). The efficiency of deep-ocean CO2 sequestration is regulated by the relative balance between inorganic and organic carbon export respectively acting through the Biological Carbon Pump (BCP) and the CCP. The process of calcification by planktonic calcifying species (carbonate shell producers) provides the major driver for the CCP. In most of the world's oceans, the species responsible are principally phytoplankton taxa, such as coccolithophores and foraminifera. However, in the northern Scotia Sea, the present study shows that it is thecosome pteropods, a zooplankton taxa, which mainly drive the CCP. Ocean acidification is starting to make waters in this part of the Southern Ocean corrosive to pteropods as a result of their comparatively vulnerable aragonite shells. Through lowering pteropod population abundance, this study shows that ocean acidification could also have repercussions to CO2 uptake and sequestration at globally important levels. 1.

Gliders show this to be a wide scale process and time series captures seasonal evolution. Overflows across bathymetric sills propagate cooler thermocline water to depth but increased winter sea ice cover leads to a shallower thermocline and therefore warmer waters being mixed with the deep/mid-depth waters that can cross the sill. These processes are extremely hard for models to capture. Airborne geophysics - A major paper "An embayment in the East Antarctic basement constrains the shape of the Rodinian continental margin" represents a new and exciting study for the first time providing constraints on the subglacial geology in the South Pole region. East Antarctic provinces lay at the heart of both Rodinian and Gondwanan supercontinents, yet poor exposure and limited geophysical data provide few constraints on the region's tectonic evolution. The shape of the Mawson Continent, the stable nucleus of East Antarctica, is one of Antarctica's most important, but contested features, with implications for global plate reconstructions and local tectonic models. The publication shows a major marginal embayment, 500-700 km wide, which cuts into the East Antarctic basement in the South Pole region. The embayment help define the East Antarctic nucleus for supercontinental reconstructions, while the inherited marginal geometry likely influenced evolution of the paleo-Pacific margin of Gondwana. The paper was published in Nature Communications Earth and Environment (2022) 3:52, https://doi.org/10.1038/s43247-022-00375-z, www.nature.com/commsenv. In terms of impact, the article is in the 96th percentile (ranked 10,039th) of the 329,535 tracked articles of a similar age in all journals. This funding stream has supported provision of an instrumented aircraft for atmospheric science that has underpinned several projects/programmes including NERC- and EU-funded, UK and international. Studies have included clouds, aerosol, air quality, methane emissions, to mention just a few. This funding stream has also supported provision of ice drilling and analysis equipment. This capability has supported several externally-funded projects/programmes for UK and international science. Note that full information is provided direct to NERC every 6 months in biannual reporting. |

| Title | Acceleration of electrons by whistler-mode hiss waves at Saturn |
| Description | Radiation belts are hazardous regions found around several of the planets in our Solar System. They consist of very hot, electrically charged particles that are trapped in the magnetic field of the planet. At Saturn the most important way to heat these particles has for many years been thought to involve the particles drifting closer towards the planet. This paper builds on previous work on the emerging idea at Saturn that a different way to heat the particles is also possible where the heating is done by waves, in a similar way to what we find at the Earth. This work is reported in the paper "Acceleration of electrons by whistler-mode hiss waves at Saturn" by E.E. Woodfield et al., 2021.

| Title | Antarctic krill reflectance measurements - Spectroradiometer data |
| Description | This dataset contains reflectance spectra measurements of Antarctic krill (Euphausia superba) that were sampled from the Scotia Sea in the Southern Ocean. Reflectance measurements were made on board on freshly caught krill, using a spectroradiometer. A number of these reflectance experiments were carried out across different regions of the Scotia Sea, on male, female and juvenile krill. Reflectance measurements are given for krill in both in situ and filtered seawater, as well as for water without krill. Data are presented in terms of remote sensing reflectance (Rrs). Funding for the work was primarily through a bursary awarded to Anna Belcher from Antarctic Science Ltd. Additionally, funding from the BAS ecosystems programme supported the project. The Natural Environment Research Council Field Spectroscopy Facility (NERC FSF) loaned the equipment required to carry out this research. |

| Title | Atmospheric observational and model datasets: Spatial distributions of nitric oxide (NO) in the winter time, high latitude Southern hemisphere atmosphere |
| Description | The data are from a study investigating nitric oxide (NO) variability in the polar mesosphere and lower thermosphere during geomagnetic storms, and the role of energetic electron precipitation in NO production. The datasets include 1) processed atmospheric datasets derived from selected NO observations by the AIM-SOFIE satellite instrument, 2) estimated electron and proton fluxes derived from POES/MEPED/SEM-2 measurements, 3) zonal and meridional wind speeds calculated using the Horizontal Wind Model (HWM14), and 4) geomagnetic indices, solar wind speed, and solar proton event (SPE) data. Funding was provided by the NERC grants NE/J022187/1 and NE/R016038/1, and the New Zealand Marsden Fund. |

| Title | BEDMAP1 - Ice thickness, bed and surface elevation for Antarctica - gridding products |
| Description | We present here BEDMAP1 (2000-2001), a suite of gridded products describing surface elevation, ice-thickness and the sea floor and subglacial bed elevation of the Antarctic south of 60deg S. The suite includes grids representing: - ice-sheet thickness over the ice sheet and shelves, - bed elevation beneath the grounded ice sheet, - bathymetry to 60 degrees South including the areas beneath the ice shelves. These grids are consistent with a high-resolution surface elevation model of Antarctica. While the digital models have a nominal spatial resolution of 5 km, such high resolution is not strictly justified by the original data density over all parts of the ice sheet. The suite does however provide an unparalleled vision of the geosphere beneath the ice sheet and a more reliable basis for ice sheet modelling. The bed elevation DEM, which includes the entire geosphere south of 60 degrees South, provides an improved delineation of the boundary between East and West Antarctica and sheds new light on the morphology of the contiguous East Antarctic landmass, much of which is buried below an average of 2500 m of ice. |

| Title | BEDMAP2 - Ice thickness, bed and surface elevation for Antarctica - gridding products |
| Description | We present here Bedmap2 (2013), a suite of gridded products describing surface elevation, ice-thickness and the sea floor and subglacial bed elevation of the Antarctic south of 60deg S. We derived these products using data from a variety of sources, including many substantial surveys completed since the original Bedmap compilation (Bedmap1) in 2001. In particular, the Bedmap2 ice thickness grid is made from 25 million measurements, over two orders of magnitude more than were used in Bedmap1. In most parts of Antarctica the subglacial landscape is visible in much greater detail than was previously available and the improved data coverage has in many areas revealed the full scale of mountain ranges, valleys, basins and troughs, only fragments of which were previously indicated in local surveys. The derived statistics for Bedmap2 show that the volume of ice contained in the Antarctic ice sheet (27 million km3) and its potential contribution to sea-level rise (58 m) are similar to those of Bedmap1, but the mean thickness of the ice sheet is 4.6 % greater, the mean depth of the bed beneath the grounded ice sheet is 72 m lower and the area of ice sheet grounded on bed below sea level is increased by 10 %. The Bedmap2 compilation highlights several areas beneath the ice sheet where the bed elevation is substantially lower than the deepest bed indicated by Bedmap1. These products, along with grids of data coverage and uncertainty, provide new opportunities for detailed modelling of the past and future evolution of the Antarctic ice sheets. The compilation of Bedmap2 products was undertaken within the British Antarctic Survey's programme, Polar Science for Planet Earth. |

| Description | As part of the International Thwaites Glacier Collaboration (ITGC) 4432 km of new radar depth sounding data was acquired over the Thwaites Glacier catchment by the British Antarctic Survey. Data was collected using the PASIN polametric radar system, fitted on the BAS aerogeophysical equipped survey aircraft VP-FBL. The survey operated from Lower Thwaites Glacier camp, and focused on collecting data in regions of ice >1.5 km thick between 70 and 180 km from the grounding line. Additional profiles from the coast to the Western Antarctic Ice Sheet (WAIS) divide and over the eastern shear margin were also flown. Ice thicknesses between 418 and 3744 m were measured, with a minimum bed elevation of -2282 imaged. This dataset contains the navigation, surface elevation, ice thickness, and bed elevation data from the Thwaites Glacier 2019/20 season in the form of a CSV file. The Thwaites 2019/20 aerogeophysical survey was carried out as part of the BAS National Capability contribution to the NERC/NSF International Thwaites Glacier Collaboration (ITGC) program. Data processing was supported by the BAS Geology and Geophysics team. |

The inlet is a 3m length of antistatic tubing, with a portion left untethered so that it can move with the prevailing wind. This is to prevent icing of the inlet by allowing the inlet to stay out of the direct line of any snow or ice being blown around. Any movement from the wind should allow any hoar frost that builds up to fall off. The instrument was installed by Joshua Eveson and the primary contact for the dataset is Freya Squires. |

| Title | Counts of Antarctic fur seals from the special study beach at Bird Island South Georgia, from 1984 to 2019 |
| Description | Counts of Antarctic fur seal individuals encountered daily at the Special Study Beach (SSB) at Bird Island, South Georgia. The SSB demographic study started in in 1982 and has continued with consistent data collection methods to date. Daily values include total counts of territorial males, new females, all females present in the afternoon, new pups born, and number of dead pups. From 1984 to 1988 only pups and dead pups were recorded. From 1988 to 2001 pup cause of death was also recorded. From 2001 to 2020 females and territorial males were included in the count. Generally territorial males are counted between 1st November and 31st December, although occasional later counts are made. Similarly, females are usually counted between 1st November and the end of pupping, generally around 10th January. Null values in the male and female columns indicate that the animals were not counted on that date.

| Title | Effects of VLF transmitter waves on the inner belt and slot region (Version 1.0) |
| Description | Signals from VLF transmitters can leak from the Earth-ionosphere wave guide into the inner magnetosphere, where they propagate in the whistler mode and contribute to electron dynamics in the inner radiation belt and slot region. Observations show that the waves from each VLF transmitter are highly localised, peaking on the nightside in the vicinity of the transmitter. In this study we use ~5 years of Van Allen probe observations to construct global statistical models of the bounce-averaged pitch angle diffusion coefficients for each individual VLF transmitter, as a function of L*, Magnetic Local Time (MLT) and geographic longitude. We construct a 1D pitch-angle diffusion model with implicit longitude and MLT dependence to show that VLF transmitter waves weakly scatter electrons into the drift loss cone. We find that global averages of the wave power, determined by averaging the wave power over MLT and longitude, capture the long-term dynamics of the loss process, despite the highly localised nature of the waves in space. We use our new model to assess the role of VLF transmitters waves, hiss waves, and Coulomb collisions on electron loss in the inner radiation belt and slot region. At moderate relativistic energies, E~ keV, waves from VLF transmitters reduce electron lifetimes by an order of magnitude or more, down to the order of 200 days near the outer edge of the inner radiation belt. However, VLF transmitter waves are ineffective at removing multi-MeV electrons from either the inner radiation belt or slot region. |

| Title | Electromagnetic ion cyclotron electron diffusion coefficients calculated using Van Allen Probe EMFISIS data for a range of ion compositions |
| Description | The banded structure of Electromagnetic Ion Cyclotron (EMIC) wave spectra and their resonant interactions with radiation belt electrons depend on the cold ion composition. However, there is a great deal of uncertainty in the composition in the inner magnetosphere due to difficulties in direct flux measurements. Here we determine the sensitivity of electron diffusion by EMIC waves to the cold ion composition. The diffusion coefficients are calculated using collocated EMIC waves spectra and plasma densities observed by Van Allen Probe EMFISIS data, parameterised by Dst, using quasi-linear theory implemented in the PADIE code. Funding was provided by NERC Highlight Topic grant: NE/P01738X/1 (Rad-Sat), NERC grant: NE/V00249X/1 (Sat-Risk) and NERC grant: NE/R016038/1 |

| Description | We conduct a global survey of magnetosonic waves and compute the associated bounce and drift averaged diffusion coefficients, taking into account co-located measurements of fpe/fce, to assess the role of magnetosonic waves in radiation belt dynamics, where fpe is the plasma frequency and fce is the electron gyrofrequency.. The average magnetosonic wave intensities increase with increasing geomagnetic activity and decreasing relative frequency with the majority of the wave power in the range fcp < f < 0.3fLHR during active conditions, where fcp is the proton gyrofrequency and fLHR is the lower hybrid resonance frequency.

| Title | Electron Electromagnetic Ion Cyclotron diffusion coefficients calculated from Van Allen Probe observations |
| Description | Electromagnetic Ion Cyclotron (EMIC) wave are important for the losses of ultra-relativistic electrons from the Earth's radiation belts. In this work, statistical EMIC diffusion coefficients are calculated from Van Allen Probe A observations of EMIC waves from the entire mission. The diffusion coefficient calculations include the observed L* and activity dependent distributions in plasma density and wave spectra so that the wave-particle interactions modelled are representative of those in the radiation belts. These diffusion coefficients can be included into global radiation belt simulations such as the BAS radiation belt model. The study is published in Ross et al 2021, JGR: Space Physics. Funding was provided by National Environment Research Council Highlight Topic grant NE/P01738X/1 (Rad-Sat), National Environment Research Council grant NE/R016445/1 and NE/R016038/1. |

| Title | Extreme relativistic electron fluxes in GPS orbit: Analysis of NS41 Burst Detector Dosimeter IIR (BDD-IIR) data |
| Description | Relativistic electrons in the Earth's outer radiation belt are a significant space weather hazard. Satellites in GPS-type orbits pass through the heart of the outer radiation belt where they may be exposed to large fluxes of relativistic electrons. In this study we conduct an extreme value analysis of the daily average relativistic electron flux in GPS orbit as a function of energy and L using data from the US NS41 satellite from 10 December 2000 to 25 July 2020. The 1 in 10 year flux at L=4.5, in the heart of the outer radiation belt, decreases with increasing energy ranging from 8.2x10^6 cm^-2s^-1sr^-1MeV^-1 at E = 0.6 MeV to 33 cm^-2s^-1sr^-1MeV^-1 at E = 8.0 MeV. The 1 in 100 year is a factor of 1.1 to 1.7 larger than the corresponding 1 in 10 year event. The 1 in 10 year flux at L=6.5, on field lines which map to the vicinity of geostationary orbit, decrease with increasing energy ranging from 6.2x10^5 cm^-2s^-1sr^-1MeV^-1 at E = 0.6 MeV to 0.48 cm^-2s^-1sr^-1MeV^-1 at E = 8.0 MeV. Here, the 1 in 100 year event is a factor of 1.1 to 13 times larger than the corresponding 1 in 10 year event, with the value of the factor increasing with increasing energy. Our analysis suggests that the fluxes of relativistic electrons with energies in the range 0.6 <= E <= 2.0 MeV in the region 4.25 <= L <= 4.75 have an upper bound. In contrast, further out and at higher energies the fluxes of relativistic electrons are largely unbounded. The research leading to these results has received funding from the Natural Environment Research Council (NERC) grants NE/V00249X/1 (Sat-Risk) and NE/R016038/1. |

| Title | Ice-sounding airborne synthetic aperture radar depth profiles from Recovery Ice Stream 2016/17 and Rutford Ice Strem 2019/20 to test the RGB-Doppler-Decomposition method. |
| Description | This data set corresponds to data acquired by the British Antarctic Survey (BAS) airborne Synthetic Aperture Radar (SAR) PASIN2 (Polarimetric Airborne Scientific INstrument, mark 2), designed for deep ice sounding and basal 3d-mapping. The data set includes the processed SAR images as depth profiles in the Recovery Ice Stream and Rutford Ice Stream, respectively downstream and upstream of the grounding line, and respectively for the 2016/17 FISS (Filchner Ice Shelf System) and the 2019/20 BEAMISH (Bed Access, Monitoring and Ice Sheet History) projects, both during the Antarctic Summer. With multiple antennas for transmission and reception at 150-MHz central frequency, and an across-track physical array, PASIN2 resolves the ambiguities for distinguishing between scatterers from port and starboard directions; however, in the two SAR images of the current dataset the port/starboard ambiguities are not resolved. On this dataset the user will be able to apply the RGB Doppler Decomposition method in the Doppler domain, interpret the results, and modify the different parameters and colours to contrast the results, all with the outcome of conducting new decompositions according to other datasets and needs. The RGB Spectral Decomposition is a generalised framework to interpret the SAR images: first, the Doppler or range spectral domains are first split into three sub-bandwidths; next, to each of the three a colour of a triplet of colours is assigned; and finally the three are superposed into one single image by the addition of the three colours. If the decomposition is applied on the Doppler spectrum, the new image contains the directional information related to the Doppler frequencies: positive frequencies when the radar approaches the target, near zero frequencies when the relative distance from radar to target is near stationary, and negative when the radar leaves it behind. If the backscattering is characterised by a very broad beamwidth the target will be gray/white, and if by a very narrow beamwidth then the target will be represented by one of the colours of the triplet. This work has received funding from the NERC grant NE/L013444/1, project: Ice shelves in a warming world: Filchner Ice Shelf System (FISS), Antarctica. The 2016/17 data were collected as part of the NERC grant NE/L013770/1, project: Ice shelves in a warming world: Filchner Ice Shelf System (FISS), Antarctica. The 2019/20 data were collected as part of the BAS National Capability contribution to the NERC/NSF International Thwaites Glacier Collaboration (ITGC) program. |

| Title | In situ growth and physiological data from two Antarctic anemone species, Isotealia antarctica and Urticinopsis antarctica at Rothera Research Station (2020-2023) |
| Description | To further our understanding of Antarctic predator growth and seasonal physiology, field growth rates were measured for two soft-bodied Antarctic anemone benthic predators, Isotealia antarctica and Urticinopsis antarctica, using in situ sampling of anemones on uniquely marked tiles from Rothera Research Station from 2020-2023. Ex situ measurements of oxygen consumption and seven-day faecal output were obtained from recently collected specimens in aquaria and compared between summer and winter. Winter physiological data for Antarctic species are rare, and we tested the hypothesis that generalist feeders or predators continue to feed during the winter. There is a dearth of basic life history and physiological data from Southern Ocean species, particularly from benthic sessile predators. This is an important data gap because species inhabiting the Southern Ocean live in a more temperature stable but seasonally varying environment than temperate and tropical counterparts. This work was supported by core funding from the NERC, UKRI, UK to the British Antarctic Survey. |

| Title | In situ measurements of snow accumulation in the Amundsen Sea Embayment during 2016 |
| Description | This dataset contains measurements of snow accumulation over an 11-month period in 2016 at six sites in the Pine Island-Thwaites Glacier catchment of West Antarctica. The sites were visited on two occasions, the first in January 2016 and the second in December 2016. The accumulation rate at each site was calculated using an average density profile, based on a compilation of six low elevation sites on Pine Island Glacier (iSTAR sites 15-19, and 22; Morris et al., 2017) that are situated nearby. The average density for the top metre based on this compilation is 419 kg m-3. Further details are provided in the associated publication. |

| Title | Ionospheric boundaries derived from IMAGE satellite mission data (May 2000 - October 2002) - VERSION 2.0 |
| Description | Ionospheric boundary locations derived from IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) satellite FUV (Far Ultra Violet) imager data covering the period from May 2000 until October 2002. These include poleward and equatorward auroral boundary data derived directly from the three imagers, WIC (Wideband Imaging Camera), SI12 (Spectrographic Imager 121.8 nm), and SI13 (Spectrographic Imager 135.6 nm). These also include the OCB (open-closed magnetic field line boundary) and EPB (equatorward precipitation boundary) derived indirectly from the auroral boundaries. The data set also includes model fitted circles for all the boundary data sets for all measurement times. Chisham et al. (2022) also describe that the v2 data set also includes estimates of the OCB at each time, derived from a combination of the poleward auroral boundary measurements in combination with modelled statistical offsets between the auroral boundary and the OCB as measured by the DMSP spacecraft. The v2 data set also includes estimates of the EPB at each time, derived from a combination of the equatorward auroral boundary measurements in combination with modelled statistical offsets between the auroral boundary and the EPB as measured by the DMSP spacecraft. The v2 data set also includes model circle fit boundaries for all times for all eight raw data sets. These model circle fits were estimated using the methods outlined in Chisham (2017) and Chisham et al. (2022), which involves fitting circles to the spatial variation of the boundaries at any one time. The raw auroral boundaries were derived as outlined in Longden et al. (2010) (the original v1 data set) with the application of the additional selection criteria outlined in Chisham et al. (2022). For the creation of the original v1 data set, for each image, the position of each pixel in AACGM (Altitude Adjusted Corrected Geomagnetic) coordinates was established. Each image was then divided into 24 segments covering 1 hour of magnetic local time (MLT). For each MLT segment, an intensity profile was constructed by finding the average intensity across bins of 1 degree magnetic latitude in the range of 50 to 90 degrees (AACGM). Two functions were fit to each intensity profile: a function with one Gaussian component and a quadratic background, and a function with two Gaussian components and a quadratic background. The function with a single Gaussian component should provide a reasonable model when the auroral emission forms in a continuous oval. When the oval shows bifurcation, the function with two Gaussian components may provide a better model of the auroral emission. Of the two functions fit to each intensity profile, the one with the lower reduced chi-square goodness-of-fit statistic was deemed to be the better model for that profile. The auroral boundaries were then determined to be the position of the peak of the poleward Gaussian curve, plus its FWHM (full-width half-maximum) value of the Gaussian, to the peak of the equatorward Gaussian, minus its FWHM. In the case of the single Gaussian fit, the same curve is used for both boundaries. A number of criteria were applied to discard poorly located auroral boundaries arising from either poor fitting or incomplete data. Following Chisham et al. (2022), additional criteria were used to refine the data for the v2 auroral boundary data sets. These included dealing with anomalous data at the edges of the image fields of view, and dealing with anomalous mapping issues.

| Title | List of Early Cenozoic fossil taxa from Antarctica, Western Europe and US Gulf Coast |
| Description | This dataset comprises lists of fossil species from a polar region (Seymour Island, Antarctic Peninsula) and two tropical regions (Western Europe and US Gulf Coast) during the Early Cenozoic era. The dataset begins in the Late Maastrichtian epoch of the Cretaceous period, extends across the mass extinction event at the Cretaceous/Paleogene (K/Pg) boundary, and terminates in the late Middle Eocene (i.e., a timespan of some 30 Myr from approximately 70 to 40 Ma ago). The lists are based on four of the commonest types of fossil found at the time: two of these are bivalve molluscs and two are gastropod molluscs. Within each group (or taxonomic clade), the fossils are listed by family, starting with the taxonomically most primitive and ending with the most recent (or derived). Both genus and species names are given. The data were collected in various stages between 2009 and 2021. These lists were used to compare patterns of mass extinction across the K/Pg boundary and then subsequent evolutionary radiation of these four groups through the first 25 Myr of the Cenozoic era. Full details of this study are given in: Crame, J.A. & McGowan, A. J. In press. Origin of the tropical-polar biodiversity contrast. Global Ecology and Biogeography.

| Title | MetUM high-resolution simulations of extreme warm temperature events over South Orkney Islands from 1 to 17 January 1991 |
| Description | High-resolution simulations of extreme warm temperature events over South Georgia Islands using the UK Met Office Unified Model (MetUM) were conducted at the British Antarctic Survey. The simulations are conducted for the period 1 to 17 January 1991, which included an event in which the temperature at Signy station peaked at 17.4 degrees Celsius on 13 January 1991, as well as a series of consecutive warm events preceding this. The dataset consists of 1) 10 m zonal wind, 10 m meridional wind, 1.5 m temperature, 1.5 m dew point temperature, 1.5 m relative humidity, and mean sea level pressure at a temporal resolution of every 1 hr for the period 1 to 17 January, 2) zonal wind, meridional wind, vertical wind, and potential temperature on model levels at 00UTC 13 January, and 3) rainfall rate at 00 UTC 13 January (averaged over a 3-hr period). The MetUM is run over a domain that includes South Orkney Islands and the surrounding ocean, which comprises 120 x 120 grid points at a grid spacing of 1 km. The model output is used to investigate the detailed influence of South Orkney Islands orography on temperature, precipitation, and winds, and in particular the importance of foehn events in producing extreme warm temperatures at Signy station.

| Title | New Chorus Diffusion Coefficients for Radiation Belt Modelling |
| Description | Whistler mode chorus is an important magnetospheric wave emission playing a major role in radiation belt dynamics, where it contributes to both the acceleration and loss of relativistic electrons. In this study we compute bounce and drift averaged chorus diffusion coefficients for 3.0 < L* < 6.0, using the TS04 external magnetic field model, taking into account co-located near-equatorial measurements of the wave intensity and fpe/fce, by combining the Van Allen probes measurements with data from a multi-satellite VLF wave database. The variation of chorus wave normal angle with spatial location and fpe/fce is also taken into account. We find that chorus propagating at small wave normal angles has the dominant contribution to the diffusion rates in most MLT sectors. However, in the region 4 <= MLT < 11 high wave normal angles dominate at intermediate pitch angles. In the region 3 < L* < 4, the bounce and drift averaged pitch angle and energy diffusion rates during active conditions are primarily larger than those in our earlier models by up to a factor of 10 depending on energy and pitch angle. Further out, the results are similar. We find that the bounce and drift averaged energy and pitch angle diffusion rates can be significantly larger than the new model in regions of low fpe/fce,eq, where the differences can be up to a factor of 10 depending on energy and pitch angle.

| Title | Processed airborne radio-echo sounding data for the Thwaites Glacier 2019 survey, West Antarctica (2019/2020) |
| Description | As part of the International Thwaites Glacier Collaboration (ITGC) ~4432 km of new radar depth sounding data was acquired over the Thwaites Glacier catchment by the British Antarctic Survey. Data was collected using the PASIN-2 polametric radar system, fitted on the BAS aerogeophysical equipped survey aircraft "VP-FBL". The survey operated from Lower Thwaites Glacier camp, and focused on collecting data in regions of ice >1.5 km thick between 70 and 180 km from the grounding line. Additional profiles from the coast to the Western Antarctic Ice Sheet (WAIS) divide and over the eastern shear margin were also flown. Ice thicknesses between 418 and 3744 m were measured, with a minimum bed elevation of -2282 m imaged. Our Twin Otter aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, an iMAR strapdown gravity system, and a new ice-sounding radar system (PASIN-2). We present here the full radar dataset consisting of the deep-sounding chirp and shallow-sounding pulse-acquired data in their processed form, as well as the navigational information of each trace, the surface and bed elevation picks, ice thickness, and calculated absolute surface and bed elevations. This dataset comes primarily in the form of NetCDF and georeferenced SEGY files. To interactively engage with this newly-published dataset, we also created segmented quicklook PDF files of the radar data. |

| Title | Quasi-weekly, year-round oceanographic and ice measurements at the coastal Western Antarctic Peninsula from 1997 to 2018 |
| Description | Year-round measurements of the water column in Ryder Bay, Western Antarctic Peninsula have been collected by the Rothera Marine Assistant and associated researchers, starting in 1997 as part of the Rothera Oceanographic and Biological Time Series (RATS) to assess temporal variability in physical and biogeochemical oceanographic properties. The data were collected using instrumentation deployed from rigid inflatable boats, or through instrumentation deployed through holes cut in the sea ice when the bay is frozen over in winter. Data collected include profiles to about 500m depth with a conductivity-temperature-depth (CTD) system that produces measurements of temperature, salinity, fluorescence and photosynthetically-active radiation (PAR). Individual water samples are collected with a Niskin bottle from a standard 15m depth, with some samples also collected from the surface layer. These individual samples are analysed for size-fractionated chlorophyll, macronutrients (nitrate, nitrite, ammonium, orthophosphate and silicic acid), stable isotopes of oxygen in seawater, and some ancillary parameters. The bottle data have been quality controlled using international reference standards. Profiling and water sample collection occur with quasi-weekly frequency in summer and weekly in winter, but are weather and sea ice dependent. In addition, daily assessments of sea ice concentration and sea ice type are made from nearby Rothera Research Station by visual inspection, to aid interpretation of the ocean data collected. These data constitute one of the longest time series of ocean measurements in Antarctica, with near-unique systematic data collection in winter, within either polar circle. Data collection has been supported since 1997 by the Natural Environment Research Council (NERC) through core funding supplied to the British Antarctic Survey. Since 2017, it has been supported by NERC award "National Capability - Polar Expertise Supporting UK Research" (NE/R016038/1). |

| Title | Rapid electron acceleration in low density regions of Saturn's radiation belt by whistler mode chorus waves |
| Description | Radiation belts are hazardous regions found around several of the planets in our Solar System. They consist of very hot, electrically charged particles that are trapped in the magnetic field of the planet. At Saturn the most important way to heat these particles has for many years been thought to involve the particles drifting closer towards the planet. This paper adds to the emerging idea at Saturn that a different way to heat the particles is also possible where the heating is done by waves, in a similar way to what we find at the Earth. This work is reported in the paper "Rapid electron acceleration in low density regions of Saturn's radiation belt by whistler mode chorus waves" by E.E. Woodfield et al., 2019. The data provided here enable reconstruction of all the figures in the paper. |

| Description | We present here the airborne Lidar data was collected over the Thwaites Glacier catchment and adjacent ice shelves during the 2018/19 and 2019/20 field seasons. The data was collected using a Riegl Q240i-80 scanning system mounted in the BAS aerogeophysically equipped twin otter aircraft. It provides a high resolution (0.2 to 0.4 points per m2), and high accuracy (~10 cm vertical) georeferenced and time stamped swath of surface elevation information. Each track is ~600 m wide. Such data provides critical information about how the surface of the Thwaites Glacier system is changing. The Thwaites 2019/20 aerogeophysical survey was carried out as part of the BAS National Capability contribution to the NERC/NSF International Thwaites Glacier Collaboration (ITGC) program, with additional funding for LIDAR data processing from the UK Foreign and Commonwealth Office. |

M. edulis were collected from the Godthabsfjorden near Nuuk, Greenland (64.45555 -51.14416) at the following locations and dates: Inner fjord (64.45941, -50.31030) on 11/06/2018; outer fjord (64.19666, -51.69) on 13/06/2018, and sub-tidal (64.19666, -51.69) on 13/06/2018 (outer fjord at 20-40cm below the lowest low water mark). The in situ collected inner and outer fjord intertidal animals with outer fjord subtidal animals used as controls were collected at 27 °C, 19 °C and 3 °C, respectively. Some of the outer fjord subtidal M. edulis were experimentally warmed to 22 °C and 32 °C for one hour to mimic high aerial exposure temperatures in the inner and outer fjord intertidal, respectively. RNA-Seq was performed on 5 animals for each treatment, with all subsequent bioinformatics analyses performed by Novogene, China. This work was supported by the Carlsberg Foundation, the Independent Research Fund Denmark (Danmarks Frie Forskningsfond) (DFF-International Postdoc; case no. 7027-00060B), a Marie Sklodowska-Curie Individual Fellowship (IF) under contract number 797387 and Aage V. Jensens Fond (Aage V. Jensens Foundation) and NERC-UKRI core funding to the British Antarctic Survey. |

| Impact | Sustained observations are vital for understanding change. Changes in the ocean/climate system can occur over decades, and these changes are best detected using continuous, long-term monitoring programmes. The Rothera Time Series (RaTS) is one of the most important long-term monitoring programmes in Southern Ocean science, partly because it features winter-time measurements that are difficult to obtain. |

| Impact | This process is known as the carbon pump and is a key process in the regulation of atmospheric CO2. Much of what we know about the carbon pump has been obtained through moored sediment traps deployed over annual cycles. Such moorings have given us some of the only measurements of biological activity at certain times of year in the Southern Ocean when seasonal sea-ice covers large areas. Over the last decades, these instruments have helped resolve spatial and temporal variability in the carbon pump in the Southern Ocean and its sensitivity to regional climate change. The bulk of this sequestration is likely to occur in highly productive zones such as at the South Georgia bloom. Our understanding of the fate of carbon in such sites is nevertheless limited by lack of in situ observations. SCOOBIES is making strategically important measurements on the fate of carbon both within the site of the bloom (site P3) and in a control site with lower productivity (site P2). It is also one of very small number of observatories making continuous measurements of carbonate chemistry parameters (pH and CO2 sensors) with which to document ocean acidification, which is increasing rapidly in polar regions. the WCB mooring provides a shelf-region comparison to the open-ocean measurements of sites P2 and P3. |

| Title | Statistical investigation of the frequency dependence of the chorus source mechanism of plasmaspheric hiss |
| Description | We use data from eight satellites to statistically examine the role of chorus as a potential source of plasmaspheric hiss. We find that the strong equatorial (|?m| < 6°) chorus wave power in the frequency range 50 < f < 200 Hz does not extend to high latitudes in any MLT sector and is unlikely to be the source of the low frequency plasmaspheric hiss in this frequency range. In contrast, strong equatorial chorus wave power in the medium frequency range 200 < f < 2000 Hz is observed to extend to high latitudes and low altitudes in the pre-noon sector, consistent with ray tracing modelling from a chorus source and supporting the chorus to hiss generation mechanism. At higher frequencies, chorus may contribute to the weak plasmaspheric hiss seen on the dayside in the frequency range 2000 < f < 3000 Hz band, but is not responsible for the weak plasmaspheric hiss on the night-side in the frequency range 3000 < f < 4000 Hz. The research leading to these results has received funding from the Natural Environment Research Council (NERC) Highlight Topic grant NE/P01738X/1 (Rad-Sat) and the NERC grants NE/V00249X/1 (Sat-Risk) and NE/R016038/1.

| Title | The Biological Investigations of Marine Antarctic Systems and Stocks (BIOMASS) Data Set |
| Description | The Biological Investigations of Marine Antarctic Systems and Stocks (BIOMASS) Data Set has been created as part of the BIOMASS Programme directed towards deeper understanding of the ecology of the Southern Ocean, with emphasis on krill (Euphausia superba). Data were collected during 34 cruises through a collaboration by 12 countries during three field experiments. These were: the First International BIOMASS Experiment (FIBEX) from November 1980 to April 1981, the Second International BIOMASS Experiment (SIBEX), Part 1 from October 1983 to May 1984 and Part 2 from November 1984 to April 1985. Data were collected on krill distribution from acoustic surveys and krill population structure from net-hauls. Supporting data from ichthyoplankton net-hauls, oceanographic stations (temperature, salinity, nutrients and chlorophyll-a) and observations of sea-birds at sea were also collected. The BIOMASS Data Set is composed of 43 data files, extracted from the BIOMASS Oracle relational database created by the BIOMASS Data Centre that collated and standardised the data. The validation and correction of the data were carried out during data analysis workshops by the BIOMASS Programme scientists who collected the data. The majority of the BIOMASS data have been utilized during BIOMASS workshops. However, some have not been used and must be regarded as unvalidated. The documentation accompanying the BIOMASS data set lists the known problems and validation status of the data. Funding: The BIOMASS Data Set has been generated by the BIOMASS Data Centre funded by the British Antarctic Survey. Main sponsors of the BIOMASS Programme were the Scientific Committee on Antarctic Research (SCAR) and the Scientific Committee on Oceanic Research (SCOR) in collaboration with the International Association for Biological Oceanography and the Advisory Committee on Marine Resources Research of the Food and Agriculture Organization of the UN. |

| Title | The coastline of Kalaallit Nunaat/ Greenland available as a shapefile and geopackage, covering the main land and islands, with glacier fronts updated as of 2017. |
| Description | A coastline of Kalaallit Nunaat/ Greenland covering all land and islands, produced in 2017 for the BAS map 'Greenland and the European Arctic'. The dataset was produced by extracting the land mask from the Greenland BedMachine dataset and manually editing anomalous data. Some missing islands were added and glacier fronts were updated using 2017 satellite imagery. The dataset can be used for cartography, analysis and as a mask, amongst other uses. At very large scales, the data will appear angular due to the nature of being extracted from a raster with 150 m cell size, but the dataset should be suitable for use at most scales and can be edited by the user to exclude very small islands if required. The projection of the dataset is WGS 84 NSIDC Sea Ice Polar Stereographic North, EPSG 3413. The dataset does not promise to cover every island and coastlines were digitised using the data creator's interpretation of the landforms from the images. |

| Title | Thermal physiology of the Patagonian limpet Nacella deaurata |
| Description | This is a physiological dataset for the Southern Patagonian limpet, Nacella deaurata. The limpets were collected from 2-6m depth in the Straits of Magellan near to Punta Arenas (53.164 S, 70.917 W) between Nov and the end of Jan 2018-19. A 2 month feeding experiment maintained N. deaurata at 1,4,8,11 and 14 °C for 2 months. Ingestion rate, absorption efficiency, absorption rate, oxygen consumption (uptake), scope for growth and mortality were measured. The thermal reaction norm for duration tenacity of field fresh subtidal and intertidal limpets, as well as subtidal limpets that were incubated at 8 °C for 2 months was investigated. The thermal reaction norm of radula scraping rates of field fresh limpets was measured. This work was funded by the Center FONDAP-IDEAL 15150003, ANID Chile and NERC core funding to the British Antarctic Survey. |

| Title | Time series of water pressure, water temperature and ground temperature from lakes Orajarvi (Finland), and Tomasee and Silsersee (Switzerland) from winters 2018-2021 |
| Description | These datasets show how lake water-pressure fluctuated through time over several months in seasonally-frozen catchments in winter. These catchments were in three settings: the lowland Finnish Arctic, an alpine valley and a high cirque in Switzerland. The water-pressure data are accompanied by water temperature and (except for Orajarvi), ground temperature for the same periods. Together, they were used to detect and quantify the water content of snow falling on the lake surfaces. The locations, method of data collection and analysis and the results are described in detail in Pritchard, H. D., Farinotti, D., & Colwell, S. (2021). This work was funded by Natural Environment Research Council (UK) core funding to the British Antarctic Survey, and a fellowship from the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, CH-8903 Birmensdorf, Switzerland. |

| PI Contribution | In the last 12-months KC2 Sub-glacial access and sampling has supported the US-UK ITGC teams, MELT and THOR. Access was provided through Thwaites Eastern Ice Shelf and nearby grounded ice. On the ice shelf, the 600 m hot water drilled accesses hole enabled deployment of several oceanographic profiling instruments, five under ice ROV missions, long term in-ice instrument strings, and oceanographic mooring. Using the KC2 corers, sediment cores were collected at both sites as well as through other access holes provided by a US drilling team. Filmed and broadcast by the BBC, this work has resulted in significant public interest around the world. |

| Results and Impact | The BAS ice core lab serves as a focus for engagement on climate change, which is used weekly by BAS, NERC and occassionally, by UKRI to educate, engage and enthuse a variety of visitors on the issues of climate change, and inparticular how palaeoclimate can help us understand our planet and it's likely future. The ice core experience relies on a physical experience, entering our cold room and handling ancient ice, and direct contact with ice-core scientists to influence and occassionally change minds. Our ice core labs have had several hundred visitors over the last few years, and testimonials attest to its effectiveness in altering perceptions. Lists of visitors are kept and are available on request. |
