Low-Oxygen ‘Dead Zones’ in North Pacific Linked to Past Ocean Warming

By Cheryl Dybas | NSF, Mark Floyd | OSU on Nov 20, 2015 Featured, Science/Education

A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic, conditions that led to vast marine dead zones. Results of the research, which was funded by the National Science Foundation (NSF), are published today in the journalNature. “This […]

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

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 […]
