Northern oceans used to pump carbon dioxide into the atmosphere

Mon, 27 Mar 2017 08:32:46 EDT ~ Norwegian Sea acted as carbon dioxide source in the past. It pumped the greenhouse gas into the atmosphere instead of absorbing it, as it does today, report scientists. Find out more...

Polar fronts oceanographic barrier is not as impermeable for bryozoans of the Southern Ocean as thought

Fri, 24 Mar 2017 10:55:20 EDT ~ The polar front, an oceanographic barrier between the Austral Ocean and its surrounding water masses, is not the impermeable biogeograpgical barrier it was thought to be, according to a new article. Find out more...

Corals die as global warming collides with local weather in the South China Sea

Thu, 23 Mar 2017 10:58:24 EDT ~ In the South China Sea, a 2C rise in the sea surface temperature in June 2015 was amplified to produce a 6C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study.

Sea ice extent sinks to record lows at both poles

Wed, 22 Mar 2017 14:31:49 EDT ~ The Arctic sea ice maximum extent and Antarctic minimum extent are both record lows this year. Combined, sea ice numbers are at their lowest point since satellites began to continuously measure sea ice in 1979. Find out more...

Upper part of Earths magnetic field reveals details of a dramatic past

Wed, 22 Mar 2017 12:28:34 EDT ~ Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about the Earths crust. The result is the release of highest resolution map of this field seen from space to date. This lithospheric magnetic field is very weak and therefore difficult to detect and map from space. But with the Swarm satellites it has been possible. Find out more...

Dead zones may threaten coral reefs worldwide

Tue, 21 Mar 2017 12:25:21 EDT ~ Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone -- a low-oxygen area that snuffs out marine life -- rather than by ocean warming or acidification.

Last remnant of North American ice sheet on track to vanish

Mon, 20 Mar 2017 14:38:56 EDT ~ The last piece of the ice sheet that once blanketed much of North America is doomed to disappear in the next several centuries, says a new study. Find out more...

From entanglement to invasions of alien species: the harm caused by marine litter

Fri, 17 Mar 2017 08:26:57 EDT ~ Marine litter is a threat to the marine ecosystem, human health and economic activities. A new report sheds light on the many effects of litter in our oceans, and highlights the severity and scale of the issue. The report confirms that plastic items have the highest direct and indirect damaging impact. Find out more...

Extensive ice cap once covered sub-Antarctic island of South Georgia

Fri, 17 Mar 2017 08:24:46 EDT ~ The sub-antarctic island of South Georgia -- famous for its wildlife -- was covered by a massive ice cap during the last ice age, new research indicates. Find out more...
