New model reveals how ocean acidification challenges tiny sea snails off U.S. West Coast

New model reveals how ocean acidification challenges tiny sea snails off U.S. West Coast

NOAA Research

A tiny sea snail, sometimes called a sea butterfly because of how it flutters about traveling the ocean currents, is part of the diet for such valuable fish as salmon and cod off the U.S West Coast.

A new study models the journey of this delicate plankton from offshore to nearshore waters, describing how changing ocean chemistry along this journey affects their condition.

Study predicts decline in Dungeness crab from ocean acidification

Study predicts decline in Dungeness crab from ocean acidification

The Seattle Times

Dungeness crab are forecast to take a hit from ocean acidification driven by fossil- fuel combustion, according to a study released this past week. Though the populations of the Dungeness crab fluctuate year by year, their overall abundance by 2063 could be about 30 percent lower, according to federal fishery biologist Issac Kaplan, a co-author of the study, “We think that there will be a moderate decline in a species that is really economically important,” said Kaplan of the Dungeness, which were valued at some $220 million during the 2013 West Coast commercial season.

NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast

NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast

NOAA

For the first time, NOAA and partner scientists have connected the concentration of human-caused carbon dioxide in waters off the U.S. Pacific coast to the dissolving of shells of microscopic marine sea snails called pteropods.

“This is the first time we’ve been able to tease out the percentage of human-caused carbon dioxide from natural carbon dioxide along a large portion of the West Coast and link it directly to pteropod shell dissolution,” said Richard Feely, a NOAA senior scientist who led the research appearing in Estuarine, Coastal and Shelf Science. “Our research shows that humans are increasing the acidification of U.S. West Coast coastal waters, making it more difficult for marine species to build strong shells.”

NOAA and Sea Grant fund $800,000 in research to understand effects of ocean changes on iconic Northeast marine life

NOAA and Sea Grant fund $800,000 in research to understand effects of ocean changes on iconic Northeast marine life

NOAA’s Ocean Acidification Program (OAP) and the Northeast Sea Grant Programs joined together to prioritize and fund new research on how ocean acidification is affecting marine life including lobsters, clams, oysters, mussels and sand lance that are so important to the Northeast region. Funding includes $800,000 in federal funds from the two programs with an additional $400,000 non-federal match.
