Perfect storm under the midnight sun triggered marine heatwave and explosion of salmon lice
University of Bergen Bjerknes Centre for Climate Research
Published: 25 February 2026
A Bjerknes Centre study shows how converging warm Atlantic currents, low wind mixing and strong solar heating created a 2024 marine heatwave in northern Norway with SSTs exceeding 18C -- over 4C above average -- driving a record salmon lice outbreak.

Dredging and dumping impact coastal fluxes of sediment and organic carbon in the North Sea

Published: 22 January 2026
A 30-year analysis reveals that 200 million tons of sediment are relocated annually by dredging in the North Sea -- equal to the natural transport by all surrounding rivers -- releasing up to 500 million tons of carbon globally each year.
