These areas have been called 'glaze' surfaces due to their polished appearance. They are typically km 2 in area and are found on leeward slopes of ice-sheet undulations and megadunes. Adjacent, leeward high-accumulation regions (isolated dunes) are generally smaller and do not compensate for the local low in surface mass balance (SMB).Cited by: The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) report, which says that Antarctica is overall losing land ice. According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of billion tons of ice a year from to
A new NASA study says that Antarctica is overall accumulating ice. Still, areas of the continent, like the Antarctic Peninsula photographed above, have increased their mass loss Author: Maria-José Viñas. which allows us to locate and chart the evolution of ice sheet dynamical imbalance. 2. Ice Sheet Elevation Change We developed time series of surface elevation change across the AIS and within its principal drainage units from ERS‐1, ERS‐2, ENVISAT, and CryoSat‐2 radar altimeter observations recorded between May and MayCited by: 4.
See more on how scientists are using ice cores to study climate history. A major focus of Australia’s ice sheet research has been in the Lambert Glacier basin near the Prince Charles Mountains. The Lambert Glacier is the world’s largest glacier, at about 40km wide and km long. This system drains 10 per cent of the Antarctic ice sheet. Mizuho Plateau, the calving front of Shirase Glacier has been the subject of a number of investigations, mainly through analysis of aerial photographs (Nakawo and others,; Fujii, ).

Studies on the Ice Sheet Flow and Local Mass Budget in Mizuho Plateau, Antarctica. By Renji NARUSE Topics: Author: Renji NARUSE. Climate change can trigger long‐term loss in ice sheet mass, which in turn drives global sea level rise. To isolate this signal, short‐term fluctuations in snowfall have to be accounted for in measurements of ice sheet elevation change.
In this study, we do this by combining satellite altimetry and a Cited by: 4. A new NASA study says that an increase in Antarctic snow accumulation that be years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

There is evidence that a self-sustaining ice discharge from the West Antarctic Ice Sheet (WAIS) has started, potentially leading to its disintegration. The associated sea level rise of more than 3m would pose a serious challenge to highly populated areas including metropolises such as Calcutta, Shanghai, New York City, and Tokyo.
Here, we show that the WAIS may be stabilized through mass Cited by: 1. The study also confirmed that the flow of West Antarctica's Thwaites and Pine Island glaciers into the ocean continues to accelerate, though the rate of acceleration is slowing. In all, the study found an overall ice discharge for the Antarctic continent of 1, gigatons per year inwith an uncertainty of plus or minus 40 gigatons.

The results obtained were combined with glaciological survey data to describe the mechanism of accumulation of meteorites by ice flow in a marginal area of the East Antarctic ice sheet.

We evaluate the state of the mass balance of the Antarctic Ice Sheet over the last four decades using a comprehensive, precise satellite record and output products from a regional atmospheric climate model to document its impact on sea-level rise.
The mass loss is dominated by enhanced glacier flow in areas closest to warm, salty, subsurface circumpolar deep water, including East Antarctica Cited by: The period of study atmospheric climate models.

Researchers at University of Washington estimated the western ice sheet collapse would occur over the next to years. Other research claimed Antarctica’s eastern ice sheet was losing ice .
