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.

Bacterium Breaks Down Ammonium in Sewage and Runoff Without Oxygen

Wetlands are one of nature's plans for treating water. Home to a host of different microbes, riparian wetland soils play matchmaker to nutrient-rich runoff and bacteria that feast on nutrients and other environmental toxins. Princeton University researchers have discovered one such bacterium—Acidimicrobiaceae bacterium A6—that can break down ammonium, part of both fertilizer and sewage runoff, without oxygen. This ability could mean wastewater treatment without expensive aeration machinery. Peter Jaffé , Princeton's William L. Knapp '47 Professor of Civil Engineering and a professor at Princeton's Andlinger Center for Energy and the Environment , corresponded with EM about the latest research . Dr. Jaffé and his team first published on A6 in 2015.
