A specially designed instrument enabled researchers in the Arctic to measure turbulence within 1 meter of the interface where ice meets ocean.
Model simulations of the impact of a large-scale nuclear war reveal long lasting effects with much of the ocean not returning to pre-war levels despite the cessation of the initial cooling.
“Beautifully long arguments” between an American scientist and a Russian researcher helped clarify several fundamental assumptions about permafrost thaw.
A model of the Atlantic Meridional Overturning Circulation (AMOC), pioneered by Henry Stommel over 60 years ago, can exhibit realistic cyclic behavior if the role of Arctic salinity is included.
Advocating for the importance of Traditional Knowledges in Finland and beyond.
Cloud-to-ground lightning is found to be the most important controller of wildfire occurrence in the Artic tundra of Alaska from 2001 to 2019.
Extensive ground temperature measurements complicate our understanding of how vegetation cover, snow duration, and microtopography influence the pace of permafrost thaw in a changing climate.
Melt ponds in sea ice have thriving algal communities with startlingly high levels of photosynthetic activity.
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.
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.
