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 Greenland's bed topography is a primary control on ice flow, grounding line migration, calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warm Atlantic water (AW) that rapidly melts undercuts marine‐terminating glaciers. Here we present new compilation Greenland assimilates seafloor thickness data through mass conservation approach. A 150 m horizontal resolution topography/bathymetric map constructed with seamless transitions at...
Abstract Antarctic subglacial lakes are studied for three main scientific reasons. First, they form an important component of the basal hydrological system which is known to affect dynamics ice sheet. Second, amongst most extreme viable habitats on Earth and third, if sediments exist their floors, may contain high-resolution records sheet history. Here we present a new inventory locations, dimensions data sources 379 lakes. Several major advances responsible rise in total number from 145 at...
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...
Warming of the Antarctic Peninsula in latter half 20th century was greater than any other terrestrial environment Southern Hemisphere, and obvious cryospheric biological consequences have been observed. Under a global 1.5°C scenario, warming is likely increase number days above 0°C, with up to 130 such each year northern Peninsula. Ocean turbulence will increase, making circumpolar deep water (CDW) both warmer shallower, delivering heat sea surface coastal margins. Thinning recession marine...
There is increasing evidence that fossil-fuel burning, and consequential global heating of 1.1°C to date, has led the increased occurrence severity extreme environmental events. It well documented how such events have impacted society outside Antarctica through enhanced levels rainfall flooding, heatwaves wildfires, drought water/food shortages episodes intense cooling. Here, we briefly examine for in Southern Ocean across a variety environments timescales. We show vulnerable natural...
How do we halt global warming? Reaching net zero carbon dioxide (CO 2 ) emissions is understood to be a key milestone on the path safer planet. But how confident are that when stop emissions, also The Zero Emissions Commitment (ZEC) quantifies much warming or cooling can expect following complete cessation of anthropogenic CO emissions. To date, best estimate by Intergovernmental Panel Climate Change (IPCC) Sixth Assessment Report change, though with substantial uncertainty. In this article,...
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...
Based on field investigations in northern Russia and interpretation of offshore seismic data, we have made a preliminary reconstruction the maximum ice‐sheet extent Barents Kara Sea region during Early/Middle Weichselian Late Weichselian. Our indicate that ice sheets attained their positions prior to 50 000 yr BP, whereas northeastern flank Scandinavian Ice Sheet advanced position shortly after 17000 calendar years ago. During (25 000–10000 BP), much Russian Arctic remained ice‐free....
The locations and details of 145 Antarctic subglacial lakes are presented. inventory is based on a former catalogue lake-type features, which has been subsequently reanalysed, the results from three additional datasets. first Italian radio-echo sounding (RES) Dome C region East Antarctica, 14 new identified. These data also show that, in number occasions, multiple reflectors thought previously to be individual fact reflections same relatively large lake. This reduces total by six, but adds...
