Antarctic ice rises and rumples: Their properties and significance for ice-sheet dynamics and evolution

TL;DR: In this article, high-resolution multibeam bathymetry data was used to map glacial landforms and reconstruct palaeo ice-sheet drainage in the Ross Sea.

TL;DR: In this article, the authors present a record of glacier and ice shelf front change over the last two decades in combination with environmental variables such as air temperature, sea ice days, snowmelt, sea surface temperature, and wind direction.

TL;DR: The spatial representativeness of SMB derived from point data over the Antarctic Ice Sheet is highly variable and depends on the spatial scale of the data and the topography of the surface.

TL;DR: Rapidly accelerating climate change in the Antarctic-Southern Ocean necessitates a Framework for UnderStanding Ice-Ocean iNteractions (FUSION) to address high uncertainty in ice-ocean interactions, proposing a combined observational-modelling approach to prioritize research and implementation.

TL;DR: Bedmap2 as discussed by the authors is a suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60° S. In particular, the Bedmap2 ice thickness grid is made from 25 million measurements, over two orders of magnitude more than were used in Bedmap1.

TL;DR: Detailed glaciological estimates of ice-shelf melting around the entire continent of Antarctica show that basal melting accounts for as much mass loss as does calving, making ice- shelf melting the largest ablation process in Antarctica.

TL;DR: In this paper, the results of boundary layer theory for ice flux in the transition zone against numerical solutions that are able to resolve the transition zones were verified. But the results were not applied to the large-scale dynamics of a marine ice sheet.

TL;DR: Satellite laser altimetry and modelling of the surface firn layer are used to reveal the circum-Antarctic pattern of ice-shelf thinning through increased basal melt, which implies that climate forcing through changing winds influences Antarctic ice-sheet mass balance, and hence global sea level, on annual to decadal timescales.
