Underwater Sounds Help Reveal Extent of Glacial Calving

by Elise Overgaard 9 December 20229 December 2022

If a glacier calves into the Arctic Ocean, does it make a sound? Some scientists say yes and have devised a clever way to use those sounds to calculate the size of the fallen ice chunks.

Arctic Sea Ice is Crucial for Forecasting Ural Blocking

by Yimin Liu 12 May 202221 December 2022

By solving the nonlinear optimization problem, sea ice concentration in Greenland, Barents and Okhotsk Seas is found crucial for prediction of strong and long-lasting Ural blocking formation.
