Groundwater Flow May Contribute to Submarine Permafrost Thaw

by Jack Lee 18 May 202218 May 2022

New, detailed surveys from the Beaufort Sea reveal a seafloor depression the size of a city block associated with permafrost thaw and likely influenced by the movement of groundwater below.

Arctic Sea Ice is Crucial for Forecasting Ural Blocking

by Yimin Liu 12 May 202210 May 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.

Wildfires Will Worsen, Warns U.N. Report

by Meghie Rodrigues 30 March 20226 May 2022

From the equator to the Arctic, wildfires are likely to increase, and climate change can make them worse, according to a new United Nations report. Action is still possible, say the authors.

Can Aurora Enhance Radar Monitoring of Arctic Aviation?

by Michael A. Hapgood 2 February 202215 March 2022

Enhanced E-region ionization produced by the aurora can be used to reflect signals from over-the-horizon radars and thus enable those radars to better monitor aviation in Arctic regions.
