Ocean acidification: University of Washington's giant plastic bags help control research conditions
With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification.
Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands.
“These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.Read More
National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action.
“We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks.
To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.Read More
Yellow perch are a species central to the culture and economy surrounding Lake Erie. With the largest commercial fishery and a prolific sportfishing industry, Lake Erie's yellow perch are a treasured study subject for environmental scientists. Daily bag limits and other public wildlife regulations rely heavily on the work of scientists like Ann Marie Gorman, one of the Fisheries Biologists responsible for coordinating ODNR ’s Central Basin Bottom Trawl Survey.
The survey, ongoing since 1990, conducts seasonal assessments of the bottom fish community in Erie. It aims to index annual recruitment and catch-at-age of yellow perch.Read More
