ANTHROPIC: Assessment of climate change's impacts on radioecological safety of subpolar and Nordic marine environment

The ANTHROPIC project uses the Norwegian Earth System Model (NorESM) to project the future dispersion patterns of radionuclides in the North Atlantic-Arctic Ocean and to assess the associated radioecological risks, taking into account of different climate change scenarios and potential sources of radioactive contaminants.

In the proposal, we are aiming to use the state-of-the-art Norwegian Earth System Model (NorESM) to project the future dispersion patterns of radionuclides in the North Atlantic-Arctic Ocean and to assess the associated radioecological risks with the consideration of different climate change scenarios and potential sources of radioactive contaminants defined by the end users, i.e. Nordic nuclear safety authorities.

One step closer to improved tools for studying the past and measuring the future Arctic Ocean

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.

Forecasting nutrients in the Arctic Ocean and North Atlantic

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.

Seven decades of environmental change at deep-sea sponge grounds

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.

Marine sediments can tell us about climate change in eastern Africa 2 million years ago

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.

A hidden gem article: How risky are oil spills along the Norwegian coast for fish?

Annette Samuelsen, research leader of our Ocean Modelling Group, published an article in 2019 that recently made it on the “Hidden gems” list of the ICES Journal of Marine Science! These articles are hand-picked by the Editor-in-Chief for being of high quality and special interest, but not having many citations yet.
