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.

NOAA Alaska buoy network to monitor North Pacific ocean acidification
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.

Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no
The sea lamprey’s days in the Great Lakes could be numbered. That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes. So, can you remove enough sea lamprey to make them disappear? “Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?” While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.
