Ocean melting has thinned Antarctica’s ice shelves at an increasing rate over the past two decades, leading to loss of grounded ice. The Ross Ice Shelf is currently close to steady state but geological records indicate that it can disintegrate rapi

Once an ice sheet grows beyond a critical thickness, the basal thermal regime favors melting and development of subglacial water networks. Subglacial water is necessary for bedrock erosion, but the exact mechanisms that lead to preservation of subgla

When basal meltwater refreezes, the resulting warm ice can influence the flow dynamics of the ice sheet above. An analysis of airborne gravity and radar data identifies extensive basal-ice units across the northern Greenland ice sheet that coincide w

[1] Subglacial water in continental Antarctica forms by melting of basal ice due to geothermal or frictional heating. Subglacial networks transport the water from melting areas and can facilitate sliding by the ice sheet over its bed. Subglacial wate

Airborne gravimetry has played a vital role in contributing to our knowledge of the subglacial environment in polar regions. Previous programs have produced extensive gravity data sets in Antarctica, but the resolution and accuracy of the data have b

SUMMARY –Myosin was extracted from bovine and rabbit skeletal muscles from freshly slaughtered carcasses and after storage at 2°C for times up to 8 days. The amount of myosins extracted and ATPase activities were constant up to 2 days storage of b

Accurate quantification of surface snow accumulation over Antarctica is a key constraint for estimates of the Antarctic mass balance, as well as climatic interpretations of ice-core records. Over Antarctica, near-surface winds accelerate down relativ
