Life below the water

Although oceans and seas cover more than 70 per cent of the Earth’s surface, there are still large gaps in the knowledge about the sea. Goal 14 is about how we should manage and rebuild marine resources.

Marine activities have long been a strength and high profile area for the University of Gothenburg. The research conducted involves studies of species and biological diversity, how climate change affects the sea and how the sea can be used for sustainable production of food and renewable energy.

More aquaculture

There is major growth potential in marine aquaculture. In cooperation between the academic and business communities, a number of aspects are being studied of expanded aquaculture, primarily the cultivation of fish, shellfish such as scallops and oysters, and algae.

The goal is to design sustainable systems for cultivation based on the concept of circular ecology, which means that no nutrients are wasted. Scallops and algae make use of surplus fish food, which in turn become food, fish food or biogas. The solutions being developed will also be able to be applied elsewhere, such as in developing countries in Africa.

Studies of emissions

Many research projects are about various forms of emissions. Microplastics – small particles from human plastic consumption have received attention in recent years as one of the great potential environmental hazards. Studies are under way, for example, of how microplastics interact with other chemicals, how and where the particles are generated and how they spread in the sea and ecosystems.
Researchers are also investigating how shipping affects the sea’s chemistry and the marine microbial ecosystem. The questions are about how sulphur oxides, nitrogen oxides, chemicals, trace metals and other particles from ships affect the marine environment.

Ocean acidification is a consequence of human emissions of carbon dioxide since a large part of the carbon dioxide emitted to the atmosphere is captured by the sea and changes the sea’s chemistry. Researchers are studying how acidifying substances and rising temperatures affect the sea’s chemical processes, which in turn have consequences for life in the sea and a sustainable use of the sea as a resource.

This is goal 14: Life below water

The world’s oceans – their temperature, chemistry, currents and life – drive global systems that make the Earth habitable for humankind.

Our rainwater, drinking water, weather, climate, coastlines, much of our food, and even the oxygen in the air we breathe, are all ultimately provided and regulated by the sea. Throughout history, oceans and seas have been vital conduits for trade and transportation.
