Ocean acidification may reduce sea scallop fisheries

Fri, 21 Sep 2018 15:14:35 EDT ~ Each year, fishermen harvest more than $500 million worth of Atlantic sea scallops from the waters off the east coast of the United States. A new model, however, predicts that those fisheries may potentially be in danger. Find out more...

Glacial engineering could limit sea-level rise, if we get our emissions under control

Thu, 20 Sep 2018 10:21:38 EDT ~ Targeted engineering projects to hold off glacier melting could slow down ice-sheet collapse and limit sea-level rise, according to a new study. While an intervention similar in size to existing large civil engineering projects could only have a 30 percent chance of success, a larger project would have better odds of holding off ice-sheet collapse. But the researchers caution that reducing emissions still remains key to stopping climate change and its dramatic effects. Find out more...

Scientists identify three causes of Earth's spin axis drift

Wed, 19 Sep 2018 19:59:06 EDT ~ Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin axis drift -- contemporary mass loss primarily in Greenland, glacial rebound, and mantle convection.

Unprecedented ice loss in Russian ice cap

Wed, 19 Sep 2018 14:49:10 EDT ~ In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study. That dwarfs the ice's previous average speed of about 2 inches per day and has challenged scientists' assumptions about the stability of the cold ice caps dotting Earth's high latitudes.

Moderate warming could melt East Antarctic Ice Sheet

Wed, 19 Sep 2018 13:30:41 EDT ~ Parts of the world's largest ice sheet would melt if Antarctic warming of just 2C is sustained for millennia, according to international research. Scientists used evidence from warm periods in Earth's history to see how the East Antarctic Ice Sheet might react to a warming climate. Find out more...

Florida Keys' corals are growing but have become more porous

Tue, 18 Sep 2018 11:08:47 EDT ~ Researchers have long questioned what impact climate change has on the rate at which corals are growing and building reef habitats in the Florida Keys. A new study explored this topic, finding both good and bad news. The rate of coral skeletal growth in the Florida Keys has remained relatively stable over time, but the skeletal density of the region's corals is declining, possibly due to ocean acidification.

Natural climate oscillations in north Atlantic linked to Greenland ice sheet melt

Tue, 18 Sep 2018 11:08:38 EDT ~ Scientists have known for years that warming global climate is melting the Greenland Ice Sheet, the second largest ice sheet in the world. A new study, however, shows that the rate of melting might be temporarily increased or decreased by two existing climate patterns: the North Atlantic Oscillation (NAO), and the Atlantic Multidecadal Oscillation (AMO).

Micronizing ocean plastics threaten sea turtle populations, ocean life cycle

Mon, 17 Sep 2018 13:59:30 EDT ~ Ingestion of degrading ocean plastics likely poses a substantial risk to the survival of post-hatchling sea turtles because the particles can lead to blockages and nutritional deficiencies, according to new research. Find out more...

Large-scale shift causing lower-oxygen water to invade Canada's Gulf of St. Lawrence

Mon, 17 Sep 2018 11:16:00 EDT ~ Rapid deoxygenation in the Gulf of the St. Lawrence is caused by shifts in two of the ocean's most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway. Find out more...

New soft coral species discovered in Panama

Fri, 14 Sep 2018 15:43:42 EDT ~ Another new coral found in Panama's Coiba National Park, a UNESCO National Heritage Site, the location of the Smithsonian's newest research site. Find out more...
