Another good year for Chesapeake Bay's underwater grasses

Thu, 27 Apr 2017 12:09:28 EDT ~ An annual survey shows the abundance of underwater grasses in Chesapeake Bay increased 8 percent between 2015 and 2016, continuing an upward trend initiated in 2012. Find out more...

Cold-water corals: Acidification harms, warming promotes growth

Thu, 27 Apr 2017 10:06:46 EDT ~ The cold-water coral Lophelia pertusa is able to counteract negative effects of ocean acidification under controlled laboratory conditions when water temperature rises by a few degrees at the same time. Whether this will also be possible in the natural habitat depends on the degree of change in environmental conditions, researchers argue. Find out more...

Ocean warming to cancel increased carbon dioxide-driven productivity

Thu, 27 Apr 2017 09:17:32 EDT ~ Researchers have constructed a marine food web to show how climate change could affect our future fish supplies and marine biodiversity. Find out more...

Genes that help trout find their way home

Wed, 26 Apr 2017 15:38:04 EDT ~ In the spring when water temperatures start to rise, rainbow trout that have spent several years at sea traveling hundreds of miles from home manage, without maps or GPS, to find their way back to the rivers and streams where they were born for spawning. Researchers have identified genes that enable the fish to perform this extraordinary homing feat with help from Earth's magnetic field. Find out more...

'Whispering' keeps humpback whales safe from killer whales

Wed, 26 Apr 2017 09:33:14 EDT ~ Newborn humpback whales 'whisper' to their mothers to avoid being overheard by killer whales, researchers have discovered. The recordings were the first obtained from tags directly attached to the whales. Find out more...

'Unicorn' shipworm could reveal clues about human medicine, bacterial infections

Tue, 25 Apr 2017 17:16:52 EDT ~ A dark slithering creature four feet long that dwells in the foul mud of a remote lagoon in the Philippines has been discovered by researchers. They say studying the animal, a giant shipworm with pinkish siphons at one end and an eyeless head at the other, could add to our understanding of how bacteria cause infections and, in turn, how we might adapt to tolerate--and even benefit from--them.

Overfishing in one of world's most productive fishing regions, new study suggests

Tue, 25 Apr 2017 14:31:01 EDT ~ Scientists used images from satellites and flyovers to count the number of small boats, or pangas, to find that fishing in Gulf of California, which separates Baja California and mainland Mexico, is over capacity. The analysis suggests that future investment in the region's fisheries may not be economically or ecologically viable. Find out more...

Thought Antarctica's biodiversity was doing well? Think again

Tue, 25 Apr 2017 14:30:58 EDT ~ Antarctica and the Southern Ocean are not in better environmental shape than the rest of the world. Find out more...

33 percent of seafood sold in six DC eateries mislabeled, study finds

Tue, 25 Apr 2017 09:23:34 EDT ~ Scientists used a powerful genetic technique to test seafood dinners sold in six District restaurants and found 33 percent had been mislabeled. The swaps, they found, were mostly with closely related species, say the investigators. Find out more...

Global warming making oceans more toxic

Mon, 24 Apr 2017 15:38:09 EDT ~ Climate change is predicted to cause a series of maladies for world oceans including heating up, acidification, and the loss of oxygen. A newly published study demonstrates that one ocean consequence of climate change that has already occurred is the spread and intensification of toxic algae. Find out more...
