Declines shellfish species rocky seashores climate-driven changes
2020/10/30
The waters of the Gulf of Maine are warming faster than oceans almost anywhere on Earth. As the level of carbon dioxide rises in the atmosphere, it's absorbed by the sea, causing pH levels to fall. Oc...
Seagrasses restored to Virginia bays are flourishing（图）
Seagrasses restored Virginia bays flourishing
2020/10/23
In the late 1920s, a pathogen began killing seagrasses in Virginia's seaside bays. A 1933 hurricane finished them off. For more than a half-century, the bay bottoms were muddy and barren. Gone were th...

coastal flooding disproportionately river delta populations
2020/10/16
Thirty-one million people living in river deltas are at high risk of flooding and other impacts from tropical cyclones and climate change, according to a study by Indiana University...
Greenland is on track to lose ice faster this century than in any other over the past 12,000 years（图）
Greenland lose ice faster century past 12,000 years
2020/10/10
Greenland's rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes.The U.S. National Science Foundation-supported researc...

Microplastic pollution harms lobster larvae
2020/10/10
Microplastic fiber pollution in the ocean affects larval lobsters at each stage of their development, according to new research. A U.S. National Science Foundation-funded study published in the&#...

Sentinels ocean acidification survived Earth last mass extinction
2020/10/10
Two groups of tiny, delicate marine organisms -- sea butterflies and sea angels -- were surprisingly resilient in the face of dramatic global climate change and Earth's most recent mass extinction eve...
Microbial diversity below the seafloor is as rich as on Earth's surface（图）
Microbial seafloor rich Earth's surface
2020/10/30
For the first time, researchers have mapped the biological diversity in marine sediment, one of Earth's largest global biomes. Although marine sediment covers 70% of Earth's surface, little was known ...

Scientists investigate marine heatwaves shifting ocean currents
2020/10/10
North America experienced a series of dangerous heatwaves during the summer of 2020, breaking records from coast to coast.In the ocean, extreme warming conditions are also becoming more frequent and i...
Ocean algae get 'coup de grace' from viruses--sometimes（图）
Ocean algae coup de grace viruses--sometimes
2020/9/25
Scientists have long believed that ocean viruses quickly kill algae. But new U.S. National Science Foundation-funded research shows that viruses often live in harmony with algae, and that they pr...
'Wrong-way' migrations stop shellfish from escaping ocean warming（图）
Wrong-way migrations stop shellfish escaping ocean warming
2020/9/18
Ocean warming is paradoxically driving bottom-dwelling invertebrates that are valuable to the shellfish industry –- including sea scallops, blue mussels, surf clams and quahogs –- into warmer waters a...

nutrient transport Gulf Mexico
2020/9/18
The Gulf of Mexico receives considerable levels of nutrients from the rivers that empty into it, especially the Mississippi River, causing the Gulf's northern waters to become overly enriched and more...

Ocean acidification coral osteoporosis iconic reefs
2020/9/4
Scientists have long suspected that ocean acidification is affecting corals' ability to build their skeletons, but it has been challenging to isolate the effect of acidification from the effect of sim...
During coral mass spawning events, which are in sync with the moon's cycle, stony coral colonies simultaneously release an underwater cloud of sperm and eggs for fertilization. But how do the sperm an...
