Pine Island Glacier’s ice shelf is ripping apart, speeding up key Antarctic glacier
For decades, the ice shelf helping to hold back one of the fastest-moving glaciers in Antarctica has gradually thinned. Analysis of satellite images reveals a more dramatic process in recent years: From 2017 to 2020, large icebergs at the ice…
Machine learning model doubles accuracy of global landslide ‘nowcasts’
Every year, landslides – the movement of rock, soil, and debris down a slope – cause thousands of deaths, billions of dollars in damages, and disruptions to roads and power lines. Because terrain, characteristics of the rocks and soil, weather,…
Study shows how permafrost releases methane in the warming Arctic
Researchers from Skoltech have designed and conducted experiments measuring gas permeability under various conditions for ice-containing sediments mimicking permafrost. Their results can be useful both in modeling and testing techniques for gas production from Arctic reservoirs and in tracing methane…
