The Extech pH 4 Buffer Solution is for calibrating pH and conductivity meters to ensure measurement accuracy. The easy to use, already made fresh pH buffers include a helpful table that shows what the pH value should be and what the temperature of the buffer solution measured. The rinsing solution is used for cleaning off the pH electrodes after taking the next measurement from a different solution to prevent contamination. 

  • (2) One pint bottles of pH 4 buffer

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.

Caring for the Chesapeake: Supporting the Iconic Bay Starts with Good Monitoring Data

The Chesapeake Bay is enormous: the Bay and its tidal tributaries have 11,684 miles of shoreline—more than the entire U.S. west coast. It is the largest of more than 100 estuaries in the United States and the third largest in the world. The Bay itself is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. But the Chesapeake Bay isn’t just enormous--it’s enormously important. The  Chesapeake Bay Program  reports that its watershed covers about 64,000 square miles and is home to more than 18 million people, 10 million of which live along or near the Bay’s shores.
