DMS - a climate regulating gas released by algae

Sulphuric acid is important for the formation of clouds, which in turn affect the amount of light and therefore energy reaching the Earth. However, most of the sulphuric acid would not be in the air if there were no phytoplankton in the sea. Scientists are trying to understand the role of the marine organisms in the production of sulphuric acid.

The forest of the sea

We learn a lot about vegetation on land but what about the sea? 71% of our planet is covered by oceans, home to phytoplankton, the forest of the sea. What role does it play in the oceanic ecosystem and in our climate and how do humans interfere? [more]


We compare the role of forests on land and phytoplankton in ocean ecosystems and describe how phytoplankton is involved in ocean-atmosphere exchange. [more]


Links about phytoplankton and its role in the oceans, the marine food web and interactions with the climate system. [more]
