The YSI 6565 combination pH/ORP sensor features a 'long-life' sealed gel reference, eliminating the need to refill. The ORP sensor features a platinum electrode for optimum performance. For high fouling applications, the 6565FG 'flat glass' sensor is available for wiped antifouling protection on the 6600EDS V2.

YSI pH sensors have been carefully designed to perform under all ionic strength conditions, from seawater with a conductivity of 53,000 uS/cm, to "average" freshwater lakes and rivers with conductivities of 200 to 1500 uS/cm, to pure mountain streams with conductivities as low as 15 uS/cm, which has historically been the most difficult medium with respect to accuracy, quick response to pH changes, and minimal flow dependence.

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.

Monitoring the Lake-shaping Plant Growth in Lake St. Pierre

Researchers in Quebec are taking underwater photos to get a fish-eye view of lake-shaping aquatic plants. They’re proving the use of a technique that could expand the study of plant populations that impact everything from a lake’s plankton and fish populations to its water levels.  Photo analysis could replace more expensive and labor-intensive methods. “If you want to have good data, you have to dive and collect plants and dry them and weigh them,” said Andrea Bertolo, a professor of environmental science at the University of Quebec at Trois-Rivières .  Soon, anyone with an underwater camera and a selfie stick could be contributing to this valuable science.
