Researchers from the Nansen Center, Spain, and the UK show in a recent study that they can reduce salinity errors in forecasts and reanalyses of the Arctic Ocean by using salinity data measured from a satellite, and a data assimilation technique.

Researchers from the Nansen Center and the Helmholtz-Zentrum Hereon in Germany developed a model that produces reliable biogeochemical forecasts for the Arctic Ocean and North Atlantic. It is already in use within the Copernicus Marine Service framework.

A recent study led by Annette Samuelsen investigated environmental change at deep-sea sponge grounds in the North Atlantic. She and her team were able to establish a baseline for water conditions in four different areas through simulations – over 67 years. Such a baseline is important for future studies. Sponges have far-reaching implications for life both in the ocean and on land, and their wellbeing is dependent on their environment.

A new publication in Nature shows that a shift in air circulation is responsible for the eastern African climate having changed to dry conditions about two million years ago. The authors studied a marine core to prove their hypothesis. Björn Backeberg is a co-author – he has an adjunct position with NERSC and is affiliated with Deltares in the Netherlands and the Nansen-Tutu Centre for Marine Environmental Research in South Africa.
