Gliders repeat the surveys of the 1970s, what is new since then?

The North Icelandic Irminger Current may be seen as the Gulf Stream’s little finger. Follow this finger to its tip in Stefanie Semper's account of her new study.

While in most earlier climate models, the water flowing into the Nordic Seas was too cold, current models represent both the water temperature and the resulting heat transport better.

The deep-ocean floor is the least explored ecosystem on the planet. DNA collected during 15 international deep-sea expeditions reveal the regions and organisms most important for removing carbon from the surface. Tristan Cordier writes about his new study.

Interdisciplinary results of MOSAiC drift published

Researchers unveil a new relationship for climate models linking carbon and heat uptake with the water-column stability in the Southern Ocean.

Global warming changes the conditions for ecosystems in the Barents Sea. A recent study found large variations between years and decades, though only modest changes on longer time scales.

Pollen can travel far through the air, allowing scientists who find them to trace the winds of the past. In South Georgia ancient pollen may reveal shifts in the westerlies.

With equipment normally found in hospitals, geologists can analyze material quicker. Jan Magne Cederstrøm writes about the use of CT scans in a study of debris transported by glaciers.

With a new La Niña in the Pacific, colder conditions could be expected in the North Atlantic. However, in northern Europe and Russia, climate warming balances the cooling.
