New findings highlight the need to account for large amounts of ground ice contained in frozen soil when assessing Arctic carbon cycling.
Salty snow throws off satellite-based estimates of Arctic sea ice thickness by up to 25%. A new method seeks to fix that.
On-the-ground measurements are notoriously difficult in the harsh environment of the Arctic, but satellites could help close the gap in measuring sea surface salinity.
Two cores from the East Siberian Arctic Shelf reveal how microbial communities develop over thousands of years as submarine permafrost slowly thaws.
Significant spatial and temporal patterns emerge from the first pan-Arctic comparison of oxygen demand in marine sediments.
With thawing permafrost projected to release significant amounts of carbon in response to climate change, one of the editors of JGR: Biogeosciences reflects on the slew of recent papers in this field.
A hovercraft-based ice drift station gives researchers access to previously inaccessible regions of the changing Arctic sea ice cover off the coast of Greenland.
KAIRN (Kangerlussuaq International Research Network) 2nd Annual Meeting; Acadia National Park, Maine, 4–7 May 2016
An ancient drainage basin covering one fifth of Greenland predates the ice sheet and strongly influences the modern Jakobshavn Glacier, according to a new analysis of ice-penetrating radar data.
An analysis of a seismic and gravity anomaly discovered in the middle mantle sheds new light on ancient oceans, the mantle's evolution, and ancient magmatism in the Arctic.
