Key biological mechanism is disrupted by ocean acidification

A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide added to the atmosphere ...

Personal care product chemicals found in Antarctica

A team of researchers with the Spanish Council for Scientific Research has found small amounts of cyclic volatile methylsiloxanes in soil and plant samples and also in krill and phytoplankton specimens, all taken from various ...

Huge phytoplankton bloom in ice-covered waters discovered

A team of researchers, including scientists from Woods Hole Oceanographic Institution (WHOI), discovered a massive bloom of phytoplankton beneath ice-covered Arctic waters. Until now, sea ice was thought to block sunlight ...

New research could help predict red tide

(PhysOrg.com) -- Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling's Twilight Zone: a sharp variation ...

New threat from ocean acidification emerges in the Southern Ocean

The oceans act as a carbon sink and have already absorbed more than 40% of anthropogenic carbon emissions. The majority of this CO2 has been taken up by the Southern Ocean making these waters hotspots of ocean acidification ...

How deep-ocean vents fuel massive phytoplankton blooms

Researchers at Stanford University say they have found an aquatic highway that lets nutrients from Earth's belly sweep up to surface waters off the coast of Antarctica and stimulate explosive growth of microscopic ocean algae.

Mapping the global distribution of phytoplankton

Researchers at ETH have charted the distribution of phytoplankton in the world's oceans for the first time and investigated the environmental factors that explain this distribution. They concluded that plankton diversity ...

Phytoplankton

Phytoplankton are the autotrophic component of the plankton community. The name comes from the Greek words phyton, or "plant", and πλαγκτος ("planktos"), meaning "wanderer" or "drifter". Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high enough numbers, they may appear as a green discoloration of the water due to the presence of chlorophyll within their cells (although the actual color may vary with the species of phytoplankton present due to varying levels of chlorophyll or the presence of accessory pigments such as phycobiliproteins, xanthophylls, etc.).
