BAS Geology and Geophysics

Lead Research Organisation: NERC British Antarctic Survey

Abstract

This programme works to understand the geological structure and tectonic evolution of the Antarctic continent to generate new knowledge about its key role in the evolution of the Earth System itself. Our aim is to use state of the art technologies to explore both the landscape and the deeper structure of Earth hidden beneath the thick ice sheets that cover more than 99% of Antarctica. By achieving this we will produce new geological and geophysical maps and improve models and simulations of key geological processes such as mountain building, basin formation, magmatism and crustal growth. We work collaboratively with national and international partners to deploy a combination of airborne and marine geophysics, spectral remote sensing, field mapping and geochemistry and geochronology to improve our understanding of the geological evolution of Antarctica and its super-continental linkages. Combining this with results from global geological studies we can interpret the role of Antarctica in the breakup of the Gondwana supercontinent as well as the assembly of earlier supercontinents, such as Rodinia and Columbia. Understanding Antarctic geology is also critical for comprehending the internal factors affecting ice flow dynamics and long-term ice sheet stability, in addition to climate and ocean processes. Our research provides unprecedented insights into the structure and evolution of interior East Antarctica and on the fundamental tectonic boundary between East and West Antarctica.

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 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

Results and Impact Following our publication in the Nature journal Scientific Reports by Ebbing et al., (2018) reporting on the use of enhanced satellite gravity imaging for studies of Earth's tectonics, including tantalising new views of the lost continents buried beneath the Antarctic ice sheets, we released a press release in November 2018 that had a huge level of international interest with over 300 media items worldwide.

This had significant impact showcasing to the general public, students and experts the latest advancements in satellite-based Earth Observation for global tectonics and lithosphere studies. It also helped significantly strengthen our case for new Antarctic lithosphere studies, specifically helping us in the case for our latest ESA international consortia application 4D Antarctica.

Results and Impact The 2018 William Smith Meeting of the Geological Society of London was co-organised with the help of Teal Riley from the Geology and Geophysics Team of BAS. It was an important and pioneering event that considered mineral resources in ultra-deep terrestrial environments, the deep-ocean, the polar regions and extra-terrestrial settings. It provided a platform to discuss the key global drivers for mineral extraction in frontier environments, including security of supply concerns; to assess understanding of the resource potential of these largely unexplored parts of the planet and beyond; to identify the geoscience knowledge gaps and science opportunities; hear about research and technology developments in exploration and extraction; and discuss the challenges for environmental protection and issues surrounding resource ownership, governance and the development of regulatory regimes.
