Researchers discover new nitrogen source in Arctic

Scientists have revealed that the partnership between an alga and bacteria is making the essential element nitrogen newly available in the Arctic Ocean. The microbial process of "nitrogen fixation" converts the element into ...

Small animals with big impact

Copepods, the world's most common animal, release unique substances into the oceans. Concentrations of these substances are high enough to affect the marine food web, according to new research from the University of Gothenburg. ...

Ocean life in 3-D: Mapping phytoplankton with a smart AUV

Phytoplankton form the base of the marine food chain but are notoriously difficult for scientists to account for—a little like trying to identify and count motes of dust in the air. A truly independent underwater vehicle ...

Study shows algae thrive under Greenland sea ice

Microscopic marine plants flourish beneath the ice that covers the Greenland Sea, according to a new study in the Journal of Geophysical Research: Oceans. These phytoplankton create the energy that fuels ocean ecosystems, ...

Research unlocks secrets of iron storage in algae

New research shows that phytoplankton iron storage strategies may determine which species thrive in changing oceans and impact marine food webs, according to a recent paper in the Proceedings of the National Academy of Sciences. ...

Dormant genes brought to life in new generations

The genetic differences in phytoplankton living in close geographic proximity can be great, which has long intrigued researchers. Now, new research shows that the ability of phytoplankton to generate resting stages can be ...
