Another good year for Chesapeake Bay's underwater grasses
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.

Cold-water corals: Acidification harms, warming promotes growth
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.

Ocean warming to cancel increased carbon dioxide-driven productivity
Researchers have constructed a marine food web to show how climate change could affect our future fish supplies and marine biodiversity.

Genes that help trout find their way home
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.

Paleontologists identify new 507-million-year-old sea creature with can opener-like pincers
Paleontologists have uncovered a new fossil species that sheds light on the origin of mandibulates, the most abundant and diverse group of organisms on Earth, to which belong familiar animals such as flies, ants, crayfish and centipedes. Named Tokummia katalepsis by the researchers, the creature documents for the first time the anatomy of early mandibulates, a sub-group of arthropods with specialized appendages known as mandibles, used to grasp, crush and cut their food.

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

Mystery of the missing mercury at the Great Salt Lake
Around 2010, the deep waters of Utah's Great Salt Lake contained high levels of toxic methylmercury. Mercury measurements in waterfowl surrounding the lake led to a rare human consumption advisory for ducks. But by 2015, 90 percent of the deep mercury was gone.

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

Global warming making oceans more toxic
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.

An intimate look at the mechanics of dolphin sex
Using CT scans, researchers visualize the internal dynamics of sexual intercourse in marine mammals. The research sheds light on evolutionary forces and has practical applications for conservation efforts.

Coral reefs struggle to keep up with rising seas, leave coastal communities at risk
In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai'i, researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.

Seven years later: BP oil spill settlement funding new way to manage fish populations
Understanding the severity of the BP oil spill has led researchers to a barcoding fish eggs. This will help them to determine where fish are spawning, hopefully leading toward the creation of protected areas and a baseline should another oil spill occur.

Canary in the kelp forest: Sea creature dissolves in today's warming, acidic waters
The one-two punch of warming waters and ocean acidification is predisposing some marine animals to dissolving quickly under conditions already occurring off the Northern California coast, according to a new study.

Sea scorpions: The original sea monster
Related to both modern scorpions and horseshow crabs, sea scorpions had thin, flexible bodies. Some species also had pinching claws and could grow up to three metres in length. New research that the sea scorpions had another weapon at their disposal: a serrated, slashing tail spine.

Banning transshipment at-sea necessary to curb illegal fishing, researchers conclude
Banning transshipment at-sea -- the transfer of fish and supplies from one vessel to another in open waters -- is necessary to diminish illegal fishing, a team of researchers has concluded after an analysis of existing maritime regulations.
