Tiny organisms give big warning about planet health

San Francisco State University scientists are studying whether a hardworking microscopic organism that helps rid the planet of too much carbon dioxide will continue to work so well in the year 2100, when the Earth’s ...

Computing the ocean's true colors

When she was 17, Stephanie Dutkiewicz set sail from her native South Africa to the Caribbean islands. Throughout a three-month journey, she noticed that the color of the ocean shifted from place to place, but it wasn't until ...

Vast phytoplankton blooms may be lurking beneath Antarctic ice

Until now, it's been a common belief that the packed sea ice of the Southern Ocean blocked all light from reaching the sea beneath, preventing phytoplankton—tiny algae that are the base of aquatic food webs—from growing ...

The Carbon Cycle Before Humans

Geoengineering -- deliberate manipulation of the Earth's climate to slow or reverse global warming -- has gained a foothold in the climate change discussion. But before effective action can be taken, the Earth's natural biogeochemical ...

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 ...

Melting glaciers feed Antarctic food chain

Nutrient-rich water from melting Antarctic glaciers nourishes the ocean food chain, creating feeding "hot spots" in large gaps in the sea ice, according to a new study.

Marine plants can flee to avoid predators, researchers say

Scientists at the University of Rhode Island's Graduate School of Oceanography have made the first observation of a predator avoidance behavior by a species of phytoplankton, a microscopic marine plant. Susanne Menden-Deuer, ...

Task force recommends reducing global harvest of 'forage fish'

A task force that conducted one of the most comprehensive analyses of global "forage fish" populations issued its report this week, which strongly recommends implementing more conservative catch limits for these crucial prey ...

Ocean life triggers ice formation in clouds

Researchers have shown for the first time that phytoplankton (plant life) in remote ocean regions can contribute to rare airborne particles that trigger ice formation in clouds. Results published this week (Wednesday 9 September) ...
