Antarctica is currently losing net mass to the ocean primarily from West Antarctica and the Antarctic Peninsula, which together hold ~5.5?m of sea level rise potential. Yet, the East Antarctic Ice Sheet stores almost ten times more ice…
The Antarctic Ice Sheet is integral to Earth's climate system, influencing global energy and water cycles, and ecosystems. Enough ice is stored in regions most vulnerable to rapid retreat to cause sea levels to rise by ?15?m if they completely melted, making their stability a key concern.
Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore…
The joint TOT-Cal / CryoVExANT2011 project contributes to the validation of the CryoSat-2 altimetry mission through investigations of a key portion of the East Antarctic ice sheet near Australia’s Casey Station. Spanning parts of Law Dome and the Totten Glacier…
The TotCal / CryoVExANT2011 project is an Australian and German collaboration that contributes to the validation of the CryoSat-2 radar altimetry mission through investigations of a key portion of East Antarctica near the Australian Casey Station.
The Amery Ice Shelf, East Antarctica, undergoes high basal melt rates near the southern … limit of its grounding line where 80% of the ice melts within 240km of becoming afloat. A considerable … portion of this later refreezes downstream as marine ice.
Determining the mass balance of the Greenland and Antarctic ice sheets (GIS and AIS) has long … been a major challenge for polar science. But until recent advances in measurement technology…
We report on long-term surface elevation changes of the central Amery Ice Shelf … (AIS) by comparing elevation records spanning 4 decades (1968–2007). We use elevation … records acquired with the following methods: optical leveling (1968–1969); ERS … radar altimetry (1992–2003); GPS (1995–2006)…
Satellite remote sensing observations of three break-up events in 2008 for the Wilkins Ice Shelf (28 February … to 6 March, 27 May to 31 May, and 28 June to mid-July) provide unprecedented detail of ice shelf calving … during rapid break-up.
Because of the vast reservoirs of water mass held in the great ice sheets of Antarctica and Greenland, determining the … role that they play in global sea level has long been a major challenge of polar science. But until recent advances in … measurement technology…
We investigate ice shelf rift propagation using a … combination of GPS and seismic measurements near the … tip of an active rift in the Amery Ice Shelf. These … measurements reveal that propagation occurs in episodic … bursts…
We present a map of the distribution of marine ice accreted to the base of the Amery Ice Shelf (AIS), East Antarctica. This map is derived by converting a Digital Elevation Model (DEM) of the AIS generated from satellite radar altimeter data to an ice thickness map, assuming hydrostatic equilibrium…
We combine ERS-1 satellite radar altimeter surface elevations (Fricker and others, this issue) with six different accumulation distributions to compute balance fluxes for the Lambert Glacier-Amery Ice Shelf Drainage system.
The Lambert Glacier–Amery Ice Shelf system is a major component of the East Antarctic ice sheet. This paper presents two Digital Elevation Models (DEMs) that have been generated for the Lambert Glacier - Amery Ice Shelf system from validated ERS-1 satellite radar altimeter waveform data.
