Climate change will turn coastal Antarctica green, say scientists

Scientists have created the first ever large-scale map of microscopic algae as they bloomed across the surface of snow along the Antarctic Peninsula coast. Results indicate that this 'green snow' is likely to spread as global ...

Sea ice algae blooms in the dark

Researchers from Aarhus University have measured a new world record: Small ice algae on the underside of the Arctic sea ice live and grow at a light level corresponding to only 0.02 percent of the light at the surface of ...

Some algae like it cold

It may look pretty, but the swaths of delicately-colored, pretty "precipitation" may lead to an increase in glacial melting, according to interdisciplinary research at the University of Cincinnati.

Toxic 'marine snow' can sink quickly, persist at ocean depths

In a new study, researchers from North Carolina State University found that a specific neurotoxin can persist and accumulate in "marine snow" formed by the algae Pseudo-nitzschia, and that this marine snow can reach significant ...

Cosmopolitan snow algae accelerate melting of Arctic glaciers

The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study to be published in Nature Communications on June 22. White areas covered with snow and ice reflect sunlight; ...
