Abstract. We present Bedmap2, a new suite of gridded products describing surface elevation, ice-thickness and the seafloor subglacial bed elevation Antarctic south 60° S. derived these using data from variety sources, including many substantial surveys completed since original Bedmap compilation (Bedmap1) in 2001. In particular, Bedmap2 ice thickness grid is made 25 million measurements, over two orders magnitude more than were used Bedmap1. most parts Antarctica landscape visible much...
Abstract Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change role of humans in Earth climate system. The potential for new knowledge be gained from future substantial. Therefore, international community came together ‘scan horizon’ identify highest priority scientific questions researchers should aspire answer next two decades beyond. Wide consultation was a fundamental principle development collective, view most...
Abstract We present Bedmap3, the latest suite of gridded products describing surface elevation, ice-thickness and seafloor subglacial bed elevation Antarctic south 60 °S. Bedmap3 incorporates adds to all post-1950s datasets previously used for Bedmap2, including 84 new aero-geophysical surveys by 15 data providers, an additional 52 million points 1.9 line-kilometres measurement. These efforts have filled notable gaps in major mountain ranges deep interior East Antarctica, along West...
An International Polar Year aerogeophysical investigation of the high interior East Antarctica reveals widespread freeze-on that drives substantial mass redistribution at bottom ice sheet. Although surface accumulation snow remains primary mechanism for sheet growth, beneath Dome A, 24% base by area is frozen-on ice. In some places, up to half thickness has been added from below. These packages result conductive cooling water ponded near Gamburtsev Subglacial Mountain ridges and supercooling...
Abstract The second generation Antarctic magnetic anomaly compilation for the region south of 60°S includes some 3.5 million line‐km aeromagnetic and marine data that more than doubles initial map's near‐surface database. For new compilation, sets were corrected International Geomagnetic Reference Field, diurnal effects, high‐frequency errors leveled, gridded, stitched together. further constrain crustal architecture geological evolution Peninsula West Rift System in Antarctica, as well...
Gravity surveying is challenging in Antarctica because of its hostile environment and inaccessibility. Nevertheless, many ground-based, airborne shipborne gravity campaigns have been completed by the geophysical geodetic communities since 1980s. We present first modern Antarctic-wide data compilation derived from 13 million points covering an area 10 km2, which corresponds to 73% coverage continent. The remove-compute-restore technique was applied for gridding, facilitated levelling...
Abstract The National Aeronautics and Space Administration (NASA)’s Operation IceBridge (OIB) was a 13‐year (2009–2021) airborne mission to survey land sea ice across the Arctic, Antarctic, Alaska. Here, we review OIB’s goals, instruments, campaigns, key scientific results, implications for future investigations of cryosphere. primary goal use laser altimetry bridge gap in fine‐resolution elevation measurements from space between conclusion NASA’s Ice, Cloud, Elevation Satellite (ICESat;...
Abstract Surface meltwater that reaches the base of Greenland Ice Sheet exerts a fundamental impact on ice flow, but observations catchment‐wide movement and distribution subglacial water remain limited. Using radar‐sounding data from two seasons, we identify seasonal in western Greenland. Our analysis provides evidence widespread storage beneath wintertime. The winter is located primarily bedrock ridges with higher bed elevations excess 200 m. During melt season moves to troughs. This...
Abstract. One of the key components this research has been mapping Antarctic bed topography and ice thickness parameters that are crucial for modelling flow hence predicting future loss ensuing sea level rise. Supported by Scientific Committee on Research (SCAR), Bedmap3 Action Group aims not only to produce new gridded maps international scientific community, but also standardize make available all geophysical survey data points used in producing Bedmap products. Here, we document latest...
