Decreased plankton food quality in an acidified ocean

The increased carbon dioxide level in the atmosphere results in an acidification of our oceans. When the sea water becomes more acidic, the ecosystems are affected with changes in plankton community composition and transfer of nutrients in the food chain.

Core sampler

New bottom sampler prompts re-evaluation of the amount of carbon in ocean sea floor sediments

An improved sampling device of marine sediments reveals that previous measurements were uncertain and often directly misleading. The amount of carbon stored in the sea floors now needs to be reassessed, as it is an important entry for predicting the greenhouse effect.


Predatory fish can reduce eutrophication effects

Management measures that favour predatory fish, for example cod, can decrease eutrophication effects in coastal areas. This is the main conclusion of a new study reviewing over 50 experimental studies in the North Atlantic, being published in the Journal of Applied Ecology.
