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.

US Steel Dumping Chromium: Citizens Fighting for Lake Michigan, and Drinkable Water

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.
