New research led by scientists from the Woods Hole Oceanographic Institution in collaboration with scientists from a number of institutes has revealed that fish are playing a previously unrecognised role in ocean chemistry by naturally excreting carbonate particles that sink to the deep sea. 

Plankton powerhouses are under the spotlight in a newly published BioScience article authored by an international group of scientists including Prof Alex Poulton of Heriot-Watt University and BIO-Carbon.
Plankton, derived from the ancient Greek word meaning ‘drifter’, are a diverse group of aquatic organisms found worldwide in marine and freshwater environments.
