Nutrient enrichment

This research area investigates the inflows of nutrients from land, mechanisms for phosphorus binding in water, and sediment-water nutrient exchanges. The main goal is to improve models for management of eutrophication in the open sea and in coastal areas.

Sediment sampling in The Baltic Sea.

Seafloor animals play a bigger role in nutrient cycling than expected

Biogeochemical processes in Baltic Sea sediments provide essential ecosystem services, such as reducing eutrophication by removing nutrients or converting them to useful food sources for marine organisms. New research from Stockholm University shows that small animals in the sediment affect the cycling of nitrogen – an essential nutrient, much more than expected.

Cyanobacterial summer blooms progressively earlier in the Baltic Sea

The cyanobacterial summer bloom in the Baltic is now almost three weeks earlier than 35 years ago, according to a study published in Biogeosciences. The blooms had been predicted to become earlier in the future, as a result of climate change, but now it appears that the future is already here.

Landscape-scale effect of wetlands in reducing nutrient loads to the Baltic Sea

The Baltic Sea is heavily impacted by eutrophication due to excessive nitrogen and phosphorus loading from various anthropogenic sources. Protection, restoration and creation of wetlands are often proposed as a solution, but scientists at Stockholm University now warn that the effect of wetlands on nutrient retention is undetectable at landscape-scales.
