Details

The YSI 6561 pH sensor features a 'long-life' sealed gel reference, eliminating the need to refill. For high-fouling applications, the 6561FG '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.
Notable Specifications:
  • Range: 0 to 14 units
  • Resolution: 0.01 unit
  • Accuracy: +/-0.2 unit
  • Warranty: 1 year

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.

Researchers Find Link Between Climate Change and Gastrointestinal Illnesses

An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.
