Ocean Acidification a Culprit in Commercial Shellfish Hatcheries’ Failures

By Cheryl Dybas | NSF, Mark Floyd | OSU on Dec 18, 2014   At Sea, Featured, Science/Education  

Ocean Acidification a Culprit in Commercial Shellfish Hatcheries’ Failures

The mortality of larval Pacific oysters in Northwest hatcheries has been linked to ocean acidification. Yet the rate of increase in carbon dioxide in the atmosphere and the decrease of pH in near-shore waters have been questioned as being severe enough to cause the die-offs. Now, a new study of Pacific oyster and Mediterranean mussel […]

Warmer Pacific Ocean Could Release Millions of Tons of Seafloor Methane

Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water. Researchers found that water off the […]

Splashy blue and green hues pop from under the glassy finish of the Tinamou species’ (bird relatives of ostriches, rheas and emus) eggs. Pigments covered by a thin, smooth cuticle reveal the mystery behind these curious shells, University of Akron researchers discovered. The finding could lead to the development of glossy new coatings for ceramics […]

MESSENGER Data Suggest Recurring Meteor Shower on Mercury

MESSENGER Data Suggest Recurring Meteor Shower on Mercury

The closest planet to the sun appears to get hit by a periodic meteor shower, possibly associated with a comet that produces multiple events annually on Earth. The clues pointing to Mercury’s shower were discovered in the very thin halo of gases that make up the planet’s exosphere, which is under study by NASA’s MESSENGER […]
