Helicopter-based observations uncover warm ocean flows toward Totten Ice Shelf in Southeast Antarctica
An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.
Penguins, Robots, The Ocean and more
Climate change researchers from the University of Delaware are among those in Antarctica conducting fieldwork on penguins, ocean currents and glaciers
New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
A new study measured 38 years of change for glaciers in Kenai Fjords National Park, which lies south of Anchorage, and found that 13 of 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.
More Difficult Than Expected For Glaciers To Recover From Climate Warming
Ice shelves are floating extensions of glaciers. If Greenland’s second largest ice shelf breaks up, it may not recover unless Earth’s future climate cools considerably. This is the result of a new study, published in Nature Communications.
Study finds that landslides can have a major impact on glacier melt and movement
Using satellite imagery to study the effects of a 2019 landslide on the Amalia Glacier in Patagonia, a University of Minnesota-led research team found the landslide helped stabilize the glacier and caused it to grow by about 1,000 meters over the last three years.
Scientists report complete collapse of East Antarctica’s Conger Ice Shelf
Satellite data has confirmed that an ice shelf about the size of Manhattan has completely collapsed in East Antarctica within days of record high temperatures. The Conger ice shelf, which had an approximate surface area of 1,200 square km, collapsed around March 15, scientists confirmed today.
A recent reversal in the response of western Greenland’s ice caps to climate change
Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise.
Cause, scope determined for deadly winter debris flow in Uttarakhand, India
The Uttarakhand region of India experienced a humanitarian tragedy on Feb. 7, 2021, when a wall of debris and water barreled down the Ronti Gad, Rishiganga and Dhauliganga river valleys. This debris flow destroyed two hydropower facilities and left more than 200 people dead or missing. A self-organized coalition of 53 scientists, including researchers from the University of Washington, came together in the days following the disaster to investigate the cause, scope and impacts.
Hidden secrets written in stone:
It’s one of the best-known geological heritage sites around the world, filled with fossils and glacial secrets. Now, thanks to virtual reality technology, the ice-age past of Hallett Cove Conservation Park is revealed in a new, gamified VR experience – Beyond the Ice – and is launched this week as part of National Science Week.
