| Description | Three major findings from Geology and Geophysics are highlighted here for the 2019-2020 reporting period. Firstly, we have published as part of a new international consortia the most updated continental scale bedrock topography map for Antarctica in Nature Geoscience (Morlighem et al., 2019). The compilation represents a major update wrt ot the previous Bedmap 2.0 product we contributed to and published in 2013, and most notably includes our major new datasets acquired over 2 out of three of the previously unexplored frontiers in the Antarctic continent, including the Recovery and South Pole frontiers. This new compilation will: 1) enable more robust models of future ice sheet responses to climate and ocean change to be derived. These are, in turn, critical in order to predict how much Antarctica will contribute to future global sea level rise; 2) it provides a key product to study how the Antarctic ice sheet itself evolved and modified the underlying landscape over the last 34 Ma; 3) provides a new tool to study how the deeper structure of the Earth, including in particular the crust and lithosphere and its tectonic and geodynamic evolution have shaped the Antarctic bedrock itself. The second highlight is the work published in the Journal Geophysical Research Letters (Pappa et al., 2019) that reports on the first 3D model of the Antarctic lithosphere obtained by combining recent satellite gravity gradient, seismological and petrological modelling. Better understanding the 3D architecture and composition of the Antarctic lithosphere is essential if we are to comprehend how the Solid Earth influences the dynamics of past, present and future ice sheets. For example, understanding the viscosity of the mantle is imperative in order to better constrain processes such as glacio-isostatic adjustment (that is how the Solid Earth responded to growing and retreating ice sheets). Better constraining geothermal heat flux is also critical in order to model its influence on subglacial hydrology and basal conditions. The new 3D model of the Antarctic lithosphere is therefore an essential first step forwards and a prelude to current and future studies that will focus more also on shallower crustal structure (our current work with ADMAP 2.0+ and also 4D Antarctica). The third highlight is the paper by Jordan et al., (2020) that presents a unique and updated overview of the geology of West Antarctica, including new insights derived from recent UK and US geological and geophysical research in the Weddell Sea, Antarctic Peninsula and Marie Byrd Land respectively. As noted in this study, although major progress has been made in deciphering key stages of West Antarctica' s geological evolution including both its long-lived subduction heritage and back-arc basin development since the break of Gondwana there are still many open questions especially around the geology buried under the thick West Antarctic ice sheet and on how geology and deeper crustal and lithosphere structure also influence the most vulnerable ice sheet left on Earth. |
| Exploitation Route | The research we have performed provides major contributions to many different fields of geoscience research. First, the surveys and data compilation we have completed over East Antarctica and the Weddell Sea provided key inputs for the new Bedmachine compilation that promises to be a highly used product for the glaciological, geomorphology, geological and geophysical international research communities over next few years. Second, the research we have completed as part of the GOCE+Antarctica effort that has yielded a first 3D model of the Antarctic lithosphere is a stepping stone for the Solid Earth and GIA communities to develop new models of Solid Earth-Crysophere interactions and is already being used to set up new 4D Antarctica research into the variability of geothermal heat flux and its influence on subglacial hydrology. Our overview into West Antarctica is also important in that it provides a new platform to promote new thinking on behalf of the Antarctic community about where we should go next wrt to studying the lithospheric cradle of the West Antarctic Ice Sheet. |

| Title | Improvements to satellite gravity imaging |
| Description | Working together with the University of Kiel a new tool for exploiting and interpreting global gravity Earth Observation data has been developed. Satellite gravity gradient data are like full tensor airborne gravity data useful for studies of the lithosphere and shallower geology respectively but the simultaneous visualisation and interpretation of these data is complex even for experts in the field. Using simpler curvature and shape index products we can represent the gravity gradient data in a simpler way and we have demonstrated the utility of our products at both global and continent-wide scale, including in particular for ongoing satellite-gravity gradient studies of the Antarctic lithosphere. |

| Title | Gravity enhanced bathymetric model beneath the Brunt Ice Shelf and Stancomb-Wills Glacier Tongue |
| Description | This gridded dataset contains the revised bathymetry model beneath the Brunt Ice Shelf and Stancomb-Wills Glacier Tongue, Antarctica, The revised bathymetric model integrates existing direct bathymetry observations and free air gravity anomaly data to provide the best possible estimate of sub-ice shelf bathymetry. The input direct bathymetric/topographic observations, observation locations, and the input free air compilation are also available as additional separate grid files. All files are provided in NetCDF format in Antarctic Polar Stereographic (EPSG:3031) projection with a horizontal resolution of 2km. The output bathymetry model (Final_adjusted_topography.nc), input topographic observations (Topographic_value_grid.nc) and input topographic observation coverage (Topographic_observation_coverage.nc) have elevation values of metres, positive upwards. The input free air gravity anomaly grid (Brunt_FAA_compilation_grid.nc) has values of mGal. The bathymetric model was produced for the paper of Hodgson et al., (2019) investigating the past and future dynamics of the Brunt Ice Shelf. The publication reference is; Hodgson, D. A., Jordan, T.

| Title | Gravity-derived bathymetry for the Thwaites, Crosson and Dotson ice shelves (2009-2019) |
| Description | This dataset is an estimate of sub ice shelf bathymetry beneath the Thwaites, Crosson and Dotson ice shelves. The output bathymetry is derived from a new compilation of gravity data collected up to the end of the 2018/19 field season. The input gravity dataset includes airborne data from Operation Ice Bridge (OIB) and the NERC/NSF International Thwaites Glacier Collaboration (ITGC), and marine gravity from the R/V Nathaniel B. Palmer cruise NBP19-02. The recovered bathymetry was constrained by swath bathymetry and onshore airborne radio-echo depth sounding data in the surrounding area. Ice shelves mask the critical link between the ocean and cryosphere systems, and hence accurate sub ice shelf bathymetry is critical for generating reliable models of future ice sheet change. Included in the data release is the input free air gravity data, constraining bathymetry/sub-ice topography, and output gravity derived bathymetry. This work was funded by the British Antarctic Survey core program (Geology and Geophysics team), in support of the joint Natural Environment Research Council (NERC)/ National Science Foundation (NSF) International Thwaites Glacier Collaboration (ITGC). Additional specific support came from NERC Grants: NE/S006664/1 and NE/S006419/1, and NSF Grants: NSF1842064, NSFPLR-NERC-1738942, NSFPLR-NERC-1738992 and NSFPLR-NERC-1739003. |

| Title | High resolution aeromagnetic line data in the Ross Sea Rift collected for the ANDRILL pre-site survey (2008-09 season) |
| Description | A high resolution survey was flown opportunistically by BAS at the end of the AGAP aerogeophysical campaign during the 2008-09 Antarctic field season with NSF support from McMurdo. The main purpose was to collect data on the ice shelf for a radar pre-site survey for a major planned international ANDRILL drilling campaign at Coulman High. Due to lack of appropriate funding levels from several countries this ANDRILL drilling project has been postponed (https://www.icdp-online.org/projects/world/antarctica/coulman-high/) but the site remains nevertheless a potentially interesting target for future geoscience studies. The Coulman High project aimed to explore the range of paleo-environments, ecosystems and tectonic events that affected the Ross Sea region as it transitioned from the warm, high-CO2 Greenhouse world typical of the Eocene into the lower-CO2 and highly variable Icehouse conditions of the Oligocene and early Miocene. The aeromagnetic data released here can be used together with more extensive pre-existing international datasets to help study rift-related magmatism, faulting and sedimentary basins in the region. |

| Title | High resolution processed line aerogravity data over James Ross Island, Northern Antarctic Peninsula (1997/1998) |
| Description | Airborne gravity data were collected using a Zero Length Spring Corporation (ZLS)-modified LaCoste and Romberg model S air-sea gravimeter. The meter was mounted in a gyro-stabilised, shock mounted platform at the centre of mass of the aircraft to minimise the effect of vibrations and rotational motions. GPS data were recorded with an Ashtech Z12 dual frequency receiver in the aircraft and at a fixed base station. Differential, carrier phase, kinematic GPS methods were then used to calculate all the navigational information used for the dynamic corrections of the aerogravity data. Standard processing steps were taken to convert the raw gravity data to free air anomalies, including latitude, free air and Eotvos corrections. The vertical accelerations of the aircraft, which dominate the gravity signal recorded by the meter, were calculated by double differencing GPS height measurements. In addition, a correction was made for gravimeter reading errors caused by the platform tilting when it was subjected to horizontal accelerations (Swain, 1996). After making the above corrections, the data were low pass filtered for wavelengths less than 9 km to remove short wavelength noise from the geological signal. The data were continued to a common altitude of 2050 m and levelled. Cross-over analysis at 118 intersections yielded a standard deviation of 2.9 mGal, which is within the 1-5 mGal error range typically reported for airborne gravity surveys after levelling. Comparison between airborne measurements and previous land-based gravity data (Garrett, 1990), yielded an RMS difference of ~4.5 mGal, which is within the 2 sigma range for airborne gravity data accuracy. |

| Title | High resolution processed line aeromagnetic data over James Ross Island, Northern Antarctic Peninsula (1997/1998) |
| Description | Gravity, magnetic and radar data were acquired during a joint UK-Argentina (BAS/IAA) project, during the austral summer 1998-1999. 10,771 line km of data were acquired using a BAS Twin Otter, covering an area of 21,000 km2 that comprises the James Ross Island archipelago and the NW corner of the Weddell Sea. Gravity and magnetic data were simultaneously acquired at a constant barometric height of 2000 m, providing a terrain clearance of approximately 100 m over the highest peaks. The main flight lines were flown along an E-W direction with 2000 m spacing over James Ross Island and at 4000 m interval offshore. Tie lines, oriented meridionally, were spaced 10,000 m and extended beyond the magnetic survey to provide a regional context to the survey area as required also for airborne gravity data analysis. Magnetic data were acquired at a frequency of 10 Hz using vapour cesium magnetometers mounted on the aircraft wing tips, and resampled to 1 Hz after compensation for manoeuvre noise. A triaxial fluxgate magnetometer was mounted close to the tail of the aircraft, providing magnetic attitude information used in the data compensation. However, gravity acquisition defines that turbulent conditions are avoided and so manoeuvre noise is generally minimal. Ashtech Z12 duel frequency GPS receivers were used for survey navigation and for post-processing of the GPS data. Magnetic data were de-spiked to remove avionics noise and then smoothed (- 300 m low pass filter), before re-sampling from 10 to 1 Hz. The data were first corrected for diurnal variations using low-pass filtered base station data (30 min low-pass filter). For the internal field we used the Definitive Geomagnetic Reference Field Model 1995. The final data processing step was network levelling and microlevelling (Ferraccioli et al., 1998). We present here the processed line aeromagnetic data collected using scintrex cesium magnetometers mounted on the BAS aerogeophysical equipped Twin Otter. Data are provided as XYZ ASCII line data. |

| Impact | Airborne radar data collected during the PolarGap project funded by the European Space Agency. The radar system PASIN of the British Antarctic Survey was used for data collection. Data were collected in December 2015 in a 10 km grid above the Recovery Lakes A, B and C. The csv-data files include Latitude, Longitude, x and y coordinates (Antarctic Polar Stereographic projection, true scale at -71°, EPSG3031), air plane elevation, ice sheet surface elevation (derived from LIDAR data) and corresponding radar sample, bed elevation and corresponding radar sample, ice thickness and uncorrected relative bed return power. Elevations are given in relation to the WGS84 ellipsoid. Corresponding segy-data files contain the radar data. The radar has a center frequency of 150 MHz. As signal a 4 µs chirp was used with a bandwidth of 10 MHz. The used sampling frequency was 22 MHz. For the processing of the data a coherent moving-average filter commonly referred to as an unfocused SAR, was used. Profile P07 and P10: Data collected above the Recovery Lakes A and B. Profile P11: Data collected above the Recovery Lake C. Further data collected south of 83°C within the PolarGap project can be found on the ESA data portal (https://earth.esa.int/web/guest/campaigns). |

| Impact | Airborne radar data collected during the PolarGap project funded by the European Space Agency. The radar system PASIN of the British Antarctic Survey was used for data collection. Data were collected in December 2015 in a 10 km grid above the Recovery Lakes A, B and C. The data files include Latitude, Longitude, x and y coordinates (Antarctic Polar Stereographic projection, true scale at -71°, EPSG3031), air plane elevation, ice sheet surface elevation (derived from LIDAR data), bed elevation, ice thickness and uncorrected relative bed return power. Elevations are given in relation to the WGS84 ellipsoid. Bed returned power in all three files are referenced to a single, common refernece level. Profile P07 and P10: Data collected above the Recovery Lakes A and B. Profile P11: Data collected above the Recovery Lake C. The PolarGAP project collected many other flight data south of 83S. Data from those flights are released from ESA's data portal and UK's Polar Data Centre. |

| Title | Processed line aerogravity data over the Dufek Massif, Pensacola Mountains (1997/99 season) |
| Description | A British Antarctic Survey Twin Otter and survey team acquired 8,300 line-km of aerogeophysics data during the Austral summer of 1998/99. Gravity and radio-echo data were acquired simultaneously with the magnetic data at a compromise constant barometric height of 2,200 m, which provides a terrain clearance of 100 m over the highest peaks. Two separate surveys were conducted; one at 5 km line spacing (tie lines at 20 km) over and stretching beyond the southern extent of the Forrestal range (main survey), and one at 2 km line spacing (tie lines at 8 km) covering the Dufek Massif (detailed survey). Ashtech Z12 dual frequency GPS receivers were used for survey navigation. Pseudorange data were supplied to a Picodas PNAV navigation interface computer, which was used to guide the pilot along the pre-planned survey lines. The actual flight path was recovered, using carrier-phase, continuous, kinematic GPS processing techniques. All pseudorange navigation data were recorded at 1 Hz on a Picodas PDAS 1000, PC-based data acquisition system. We present here the processed line aerogravity data collected using Lacoste and Romberg air-sea gravity meter S83. Data are provided as XYZ ASCII line data. |

| Title | Processed line aerogravity data over the Evans Ice Stream, Southern Palmer Land region (1994/95 season) |
| Description | The survey collected a total of 11,500 km of data along 22 lines, spaced 12 km apart and oriented perpendicular to the strike of both the Bouguer anomaly field, as derived from land data (McGibbon and Smith, 1991), and the major sub-ice topographical features (Doake et al., 1983). The speed of the aircraft was set to produce a sample spacing of about 60 m and the data were collected at heights between 1600 and 2000 m above sea level. The gravity signal was recorded using a LaCoste and Romberg air/sea gravimeter, S-83, which has been kindly loaned to BAS by the Hydrographic Office of the Royal Navy. The meter was modified by the ZLS company for use in an aircraft. The equipment was deployed in a BAS De-Havilland Twin Otter aircraft. Differential, dual frequency, carrier phase, GPS measurements of the aircraft's motion were made using Trimble and Ashtech geodetic receivers and antennas. Ice thickness data were obtained using a BAS-built, radio echo sounding system (Corr and Popple, 1994). Ice-bottom returns over most of the survey area were obtained at a sample spacing of approximately 28 m. GPS measurements were tied into base stations in International Terrain Reference Frame network (Dietrich et al., 1998) and gravity measurements to base stations in the IGSN71 net (Jones and Ferris, 1999). We present here the processed line aerogravity data collected using Lacoste and Romberg air-sea gravity meter S83. Data are provided as XYZ ASCII line data. |

| Description | A British Antarctic Survey Twin Otter and survey team acquired 8,300 line-km of magnetic data during the Austral summer of 1998/99. Gravity and radio-echo data were acquired simultaneously with the magnetic data at a compromise constant barometric height of 2,200 m, which provides a terrain clearance of 100 m over the highest peaks. Two separate surveys were conducted; one at 5 km line spacing (tie lines at 20 km) over and stretching beyond the southern extent of the Forrestal range (main survey), and one at 2 km line spacing (tie lines at 8 km) covering the Dufek Massif (detailed survey). Wing-tip-mounted cesium vapour magnetometers acquired data at 10 Hz, which was resampled to 1 Hz after deletion of data corrupted by the radio echo transmissions. It is not possible to compensate the magnetic data for maneuver noise after this process as the data are under-;sampled with respect to maneuver noise. However, because gravity data was being acquired at the same time, turbulent conditions were avoided and so maneuver noise was at a minimum. Ashtech Z12 dual frequency GPS receivers were used for survey navigation. Pseudorange data were supplied to a Picodas PNAV navigation interface computer, which was used to guide the pilot along the pre-planned survey lines. The actual flight path was recovered, using carrier-phase, continuous, kinematic GPS processing techniques. All magnetic and pseudorange navigation data were recorded at 1 Hz on a Picodas PDAS 1000, PC-based data acquisition system. Data were de-spiked and then smoothed (~100 m low pass filter), before re-sampling from 10 to 1 Hz. The data were IGRF corrected, leveled and reduced to the pole in the field. A 2.5 km cell grid was produced. The negative bias to the anomaly amplitudes is a result of the poorly defined IGRF in this area. We present here the processed line aeromagnetic data acquired using scintrex cesium magnetometers mounted on the BAS aerogeophysical equiped Twin Otter. Data are provided as XYZ ASCII line data. |

| Description | We use polarimetric radar sounding to investigate variation in ice crystal orientation fabric within the near-surface (top 40-300 m) of Rutford Ice Stream, West Antarctica. To assess the influence of the fabric on ice flow, we use an analytical model to derive anisotropic enhancements of the flow law from the fabric measurements. In the shallowest ice (40-100 m) the azimuthal fabric orientation is consistent with flow-induced development and correlates with the surface strain field. Notably, toward the ice-stream margins, both the horizontal compression angle and fabric orientation tend toward 45 degrees relative to ice flow. This result is consistent with theoretical predictions of flow-induced fabric under simple shear, but to our knowledge has never been observed. The fabric orientation in deeper ice (100-300 m) is significantly misaligned with shallower ice in some locations, and therefore inconsistent with the local surface strain field. This result represents a new challenge for ice flow models which typically infer basal properties from the surface conditions assuming simplified vertical variation of ice flow. Our technique retrieves azimuthal variations in fabric but is insensitive to vertical variation, and we therefore constrain the fabric and rheology within two end-members: a vertical girdle or a horizontal pole. Our hypotheses are that fabric near the center of the ice-stream tends to a vertical girdle that enhances horizontal compression, and near the ice-stream margins tends to a horizontal pole that enhances lateral shear. ApRES radar data were collected as part of the BEAMISH Project (NERC AFI award numbers NE/G014159/1 and NE/G013187/1).

| Title | Simulations of Antarctic Ice Sheet sensitivity to climate and ocean forcing for a suite of Antarctic palaeotopographies |
| Description | We present steady-state ice thickness, bed elevation, and ice surface elevation output from simulations of the Antarctic Ice Sheet (AIS) on a suite of reconstructed Antarctic palaeotopographies using the DeConto and Pollard (DP16) ice sheet model. Ice surface mass balance inputs were provided using the GENESIS v3.0 global atmosphere general circulation model coupled to a 50 m slab ocean model, which provides boundary meteorology for the RegCM3 regional climate model. Three climate/ocean scenarios were simulated: (1) cold climate orbital parameters, preindustrial CO2 levels (280 ppm) and modern ocean temperatures, (2) a subsequent shift to warm climate orbital parameters, an increase in CO2 levels to 500 ppm, and a 5 deg C ocean temperature rise, and (3) as for (2), but with CO2 levels increased to 840 ppm. The steady-state simulations were performed on a suite of reconstructed Antarctic palaeotopographies pertaining to the following four time slices: (1) the Eocene-Oligocene boundary (EOB; ca. 34 Ma), (2) the Oligocene-Miocene boundary (OMB, ca. 23 Ma), (3) the mid-Miocene (MM; ca. 14 Ma), and (4) the mid-Pliocene (MP; ca. 3.5 Ma). Simulations were performed for minimum, median, and maximum end-member topographies, and equivalent simulations were run on the modern (ice-free) Antarctic bed topography for comparison. Further details are given in the accompanying publication. For more information, please contact G. Paxman. Funding was provided by NERC Ph.D. studentship NE/L002590/1. |

| Title | Strapdown aerogravity survey across the Brunt Ice Shelf, 2017 |
| Description | This data set contains strapdown aerogravity data collected during an airborne radar survey of the Brunt Ice Shelf as part of the NERC/BAS Life Time of Halley project. Unlike traditional stabilised platform gravity surveys strapdown gravity techniques, using an Inertial Measurement Unit (IMU) rigidly attached to the aircraft as the sensor, allow collection of gravity data during draped or turbulent flight. This was a key factor allowing for data collection during a dedicated radar survey. The survey was flown draped with an average height above the ice surface of 420m, and includes 4716 km of new data. The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL. Data are available in both Geosoft database (.gdb) and ASCII file formats (.xyz). |

| PI Contribution | The BAS Geology and Geophysics team have contributed very significantly so far to four major European Space Agency funded projects. These include: 1) the PolarGAP project; 2) the GOCE+Antarctica project; 3) the 3D Earth consortia project that includes the ADMAP 2.0+ project; 4) and most recently the new 4D Antarctica project initiated in November 2019. As part of these projects we have performed the first major modern aerogeophysical survey of the South Pole frontier to help fill in the data void in satellite gravity data coverage and helped develop the first innovative 3D models of the Antarctic lithosphere and investigated their influence on processes such as Glacio-Isostatic Adjustment (GIA). As part of 3D Earth project we are contributing towards connecting Antarctica better with other continents thereby improving our knowledge of the key missing piece of the jigsaw puzzle in the global supercontinent cycle and are linking subglacial geology to global tectonic processes. In 4D Antarctica we plan for the first time to try and reconcile remarkably different estimates of Geothermal Heat Flux for various parts of East and West Antarctica and assess in several key study regions their influence on subglacial hydrology. |
| Collaborator Contribution | The European Space Agency have funded four major international projects that involved collaborations between the University of Kiel, the Danish Technical Institute, the University of Utrecht, the Norwegian Polar Institute and BAS in the first two projects. More recently ESA has funded a wide ranging consortia of Earth scientist involved in 3D Earth and 4D Antarctica. |
| Impact | The main outputs so far have been in the form of conference presentations at several international venues including for example the European Geosciences Union and American Geophysical Union and scientific publications as well new publically available datasets and models. |

| Results and Impact | The 13th International Symposium on Antarctic Earth Science (ISAES 2019) was held at the Songdo Convensia in Incheon, Republic of Korea in 22-26 July 2019. It is the main Antarctic geosciences event held every four years. Typical attendance levels is more than 500 international geoscientist from all over the world with significant participation also by earlier career geoscientist. The invited Plenary Talk delivered at ISAES 2019 by Geology & Geophysics PI Dr Fausto Ferraccioli gave major visibility to our current geophysical research efforts in East Antarctica highlighting in particular the need to link Antarctica better to the global supercontinent cycle. This is an area of major current international geosciences research in particular as part of the IGCP 648: Supercontinent Cycles & Global Geodynamics project that brings together a diverse range of geoscience expertise to harness recent breakthroughs in order to explore the occurrence and evolution history of supercontinents through time along with the underlying geodynamic processes. One of the major outcomes of this activity at ISAES was the decision of a group of leading Solid Earth Antarctic geoscience experts to constitute a new international consortia within the Scientific Committee on Antarctic Research (SCAR) to study the Antarctic lithosphere and its global connections and impacts. This new proposal will be discussed and further considered at the SCAR Meeting to be held in Hobart |
