* April 13, 2021 / Modeling past and future glacial floods in northern Greenland / Shin Sugiyama / The river flowing from the Qaanaaq Glacier in northwest Greenland flooded in 2015 and 2016, washing out the only road connecting the small village of Qaanaaq and its 600 residents to the local airport. What caused the floods was unclear at the time. Now, by combining physical field measurements .....
* March 25, 2021 / Revealing complex behavior of a turbulent plume at the calving front of a Greenlandic glacier / Evgeny A. Podolskiy, Shin Sugiyama / As marine-terminating glaciers melt, the fresh water from the glacier interacts with the seawater to form subglacial discharge plumes, or convective water flows. These turbulent plumes are known to accelerate the melting .....
* December 07, 2020 / Key building block for organic molecules discovered in meteorites / Yasuhiro Oba / The chemistry of life runs on organic compounds, molecules containing carbon and hydrogen, which also may include oxygen, nitrogen and other elements. While commonly associated with life, organic molecules also can be created by non-biological processes and .....
* November 12, 2020 / Possible 1,000-kilometer-long river running deep below Greenland's ice sheet / Christopher Chambers / Radar surveys have previously mapped Greenland's bedrock buried beneath two to three thousand meters of ice. Mathematical models were used to fill in the gaps in survey data and infer bedrock depths. The surveys revealed the long valley, but suggested .....
* September 17, 2020 / New estimates for the rise in sea levels due to ice sheet mass loss under future climate change / Ralf Greve / One of the many effects of global warming is the increase of sea levels due to the melting and retreat of the ice sheets in the Arctic and the Antarctic. As the sea level rises, large areas of densely populated coastal land will become uninhabitable. .....
* August 24, 2020 / Japanese expedition identifies East Antarctic melting hotspot / Daisuke Hirano / Hokkaido University scientists have identified an atypical hotspot of sub-glacier melting in East Antarctica. Their findings, published in the journal Nature Communications, could further understandings and predictions of sea level rise caused by mass loss of ice sheets from the southernmost continent. .....
