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.
The Nordic Seas experience influxes of warm water and losses of heat to the atmosphere with knock-on effects on sea ice, glacier retreat, and carbon dioxide uptake.
The relative abundance of different oxidation states for this important micronutrient varies on the basis of how much available sunlight there is.
The water that filters through river deltas has a large effect on the Arctic Ocean. A new study explores factors that shape Arctic river deltas and how delta form in turn changes water flow.
A warming event in Siberia caused winds to strip sea ice from the Arctic’s Wandel Sea.
A semi-conservative tracer combining nitrate and dissolved oxygen is more accurate than traditional tracers in distinguishing between Atlantic and Pacific water mass contributions to the Arctic.
A longer ice-free season on Arctic shelves causes an increase in sediment-water interaction.
The Mackenzie River carries the bulk of freshwater flow from North America's tundra to the North Atlantic. But what about the effects of smaller rivers from Canada's Arctic islands?
