Research area Marine Science

Oceans and seas cover more than 70 percent of the Earth’s surface. Despite this, we know more about space than about what happens beneath the water’s surface. At Stockholm University, research is underway to deepen our understanding of the oceans and how they are connected to human activities.

The ocean contains a vast range of environments - from Arctic ice expanses, the Baltic Sea’s archipelagos, and tidal flats along Europe’s coasts - to coral reefs and deep-sea trenches that are far deeper than Mount Everest is high. There are also immense open-ocean areas where most of the ocean’s productivity takes place, yet which are sometimes referred to as marine deserts. Within these diverse environments exists a rich and varied plant and animal life, adapted in different ways to these changing conditions. At Stockholm University, we conduct research that explores and deepens our understanding of this complexity.

Baltic Sea Catchment

Human activities contribute to a higher pollution load in the sea. Researchers at the Baltic Sea Science Centre study the transportation of different types of pollution, such as nutrients or hazardous substances, from land to sea.

Coasts of the Baltic Sea

Our research combines knowledge from geology, oceanography, biogeochemistry, ecology, and economics to provide a broad, interdisciplinary understanding of coastal ecosystems in the Baltic Sea and how they are affected by human activities, pollution, and climate change.

Natural resources and sustainability

Our researchers and projects focus on how people utilise different environments and natural resources, and how this affects the surrounding landscape and ecosystems.

Nutrients and Eutrophication

Open Baltic Sea

Research on the open sea focuses on how the large-scale ecosystem dynamics of the Baltic Sea are changed by human impacts. Issues include eutrophication, the impact of fisheries, and how environmental toxins are transported and dispersed in the sea.

Permafrost-biogeochemistry-climate Interactions

The Arctic is warming 3-4 times faster than the global average and already now shows rapid thaw of land and subsea permafrost, vegetation shifts, increased coastal erosion, sea ice decline and changes in ocean currents.
