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

TL;DR: In this paper , the authors used MODIS satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica, from 2009 to 2019.

TL;DR: In this paper , the authors used relative sea-level observations with glacial isostatic adjustment predictions from an ice-sheet model ensemble and new estimates of postglacial thermosteric sea level and mountain glacier evolution to estimate Holocene GMSL and ice volume.

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.
