Millions of different organic compounds are dissolved in the world's oceans. These substances bind large amounts of carbon – sometimes for thousands of years. Does this affect the carbon cycle on Earth – and our climate? A multimedia story. 

Only 359 genes and the amino acid arginine as its sole energy source: The metabolism of the bacterial family Oceanoplasmataceae, newly discovered in the Gulf of Mexico, is a mystery to the German-American research team that identified it. 

Computer scientist A. Murat Eren, who goes by Meren, is convinced that microbiology can contribute to solving many global challenges. In this interview, he talks about the astonishing progress the discipline has made in recent decades.

Climate change also affects the oceans. But how can the marine life affected by it be protected beyond the scope of national jurisdiction? A new consortium of researchers including scientists from Oldenburg is investigating this.

The oceans are home to much of the planet's biodiversity. They have a major influence on our climate and provide food for billions of people. To mark World Oceans Day, researchers from Oldenburg and Bremen report on why their research is important.

Thousand-year-old sediments from the Atlantic Ocean show how biodiversity in the oceans could develop with climate change. A team from Bremen and Oldenburg is conducting joint research - also to better assess how to protect marine life in the future.

In the animal kingdom, too, there are different personalities, each with their own lifestyle: even simple marine worms live their daily lives to their own individual rhythms, a new study suggests.

A group of bacteria lives in close association with other organisms throughout the world's oceans. Microbiologist Meinhard Simon and his team at the recently completed Collaborative Research Centre Roseobacter have spent 13 years investigating what makes these microbes so successful.

Glaciers, penguins and whales: Antarctica has a special appeal - also for PhD student Lina Holthusen, who is currently conducting research there. About the challenges of working in remote places, the team spirit needed and the best Christmas present.

How does unusual heat affect the flora and fauna of the Wadden Sea? Researchers from the Institute of Chemistry and Biology of the Marine Environment and the Institute of Biology and Environmental Sciences have recently investigated this in a large-scale experiment.

Every litre of seawater is full of genetic material from different organisms. Biologist Silke Laakmann and her team are pioneering techniques that use these DNA traces to determine the biodiversity of marine communities.

There would be no oxygen on Earth were it not for sunlight; the key component in photosynthesis. Now researchers have made the surprising discovery that oxygen is also produced without sunlight, possibly deep below the ocean surface.

The research group DynaCom is investigating how stable ecosystems are in the face of natural and anthropogenic environmental changes. The German Research Foundation is now funding the project for another three years.

Coastal ecosystems naturally store carbon. But how can this potential be improved? A new joint project has recently started investigating this question.

Marine biodiversity is threatened by climate change, pollution and overfishing. Biodiversity expert Helmut Hillebrand explains in this interview how research can help to improve marine conservation.

Many animals can perceive the Earth’s magnetic field, but corresponding sensory cells haven’t been located yet. Using sophisticated experiments and technology, several research groups are hot on the trail of this mysterious sense.

Migratory species are particularly vulnerable to the effects of climate change, habitat loss and environmental pollution. Several research groups are joining forces to gain new insights into the behaviour of migratory birds.

In this interview, biologists Henrik Mouritsen and Miriam Liedvogel explain the importance of animal navigation and orientation for nature conservation – as well as for quantum technologies and autonomous vehicles.

The university recently acquired a particularly powerful electron microscope, which is also available to external users. It is capable of imaging structures as small as 0.5 billionths of a meter.

The magnetic sense of migratory birds is probably based on a special protein – this theory is supported by a new genetic study. A research team from the University of Oldenburg and the Institute of Avian Research found that the protein has been optimised through rapid selection.

Biologist Pauline Fleischmann researches desert ants and astonishing navigational abilities – both in the laboratory and in their natural environment. The insects are surprisingly good at orientating themselves in monotonous terrain.

Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study published in the journal Biology Letters. The research shows that these animals, like birds, are sensitive to magnetic inclination.

Many songbirds use the earth's magnetic field as a guide during their migrations, but radiowaves interfere with this ability. A new study has found an upper bound for the frequencies that disrupt the magnetic compass.

The Collaborative Research Center "Magnetoreception and Navigation in Vertebrates” is going into its second phase: The German Research Foundation has granted the project funding for another four years.

Many animals use the Earth's magnetic field for orientation. But exactly how they do this remains for the most part a mystery. In the Collaborative Research Centre "Magnetoreception and Navigation in Vertebrates", researchers are solving the puzzle.

Fish migrations generally take place hidden from view. Researchers from the Magnetoreception Collaborative Research Centre at the University of Oldenburg are investigating how herring, sticklebacks and coral fish find their way in the sea.

New findings on magnetic sensing in birds are presented by an international team of researchers led by Oldenburg biologist Henrik Mouritsen. The results are published in the journal Nature.
