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.

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.

A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program. The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch. 
 
“We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.” 
 
Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.
