Calving rates at tidewater glaciers vary strongly with ocean temperature
Rates of ice mass loss at the calving margins of tidewater glaciers (frontal ablation rates) are a key uncertainty in sea level rise projections. Measurements are difficult because mass lost is replaced by ice flow at variable rates, and frontal ablation incorporates sub-aerial calving, and submarine melt and calving. Here we derive frontal ablation rates for three dynamically contrasting glaci...
متن کاملQuebec medical students strike at their own pace.
1278 JAMC • 10 MAI 2005; 172 (10) The executive director of the Canada Research Chairs program says it’s understandable that neither that organization nor the Université de Montréal were informed about a fraud investigation concerning a professor they hired to head a nutrition and metabolism lab. Eric T. Poehlman was already under investigation in the United States for falsifying data when the ...
متن کاملSubglacial discharge at tidewater glaciers revealed by seismic tremor
Subglacial discharge influences glacier basal motion and erodes and redeposits sediment. At tidewater glacier termini, discharge drives submarine terminus melting, affects fjord circulation, and is a central component of proglacial marine ecosystems. However, our present inability to track subglacial discharge and its variability significantly hinders our understanding of these processes. Here ...
متن کاملIn a world of their own: working on the move
The traditional model of white collar workers inhabiting offices to carry out their tasks is no longer valid in the 21st century. Many employees now carry information with them and work while travelling, in hotels and at home. This is a relatively recent development, however, and since the information they carry with them is often sensitive, we have to consider how this new model impacts on the...
متن کاملIce-front variation and tidewater behavior on Helheim and Kangerdlugssuaq Glaciers, Greenland
[1] We used satellite images to examine the calving behavior of Helheim and Kangerdlugssuaq Glaciers, Greenland, from 2001 to 2006, a period in which they retreated and sped up. These data show that many large iceberg-calving episodes coincided with teleseismically detected glacial earthquakes, suggesting that calving-related processes are the source of the seismicity. For each of several event...
