The Extech Oyster Series pH/mV/Temperature Meter features a large LCD built into adjustable "flip-up" cover that displays pH or mV and temperature simultaneously. The microprocessor based meter has a splash proof housing and front panel tactile touch pad to slope and calibrate. The meter measures pH from 0 to 14pH, mV from -999mV to 999mV, and temperature from 32.0°F to 212.0°F (0.0°C to 100.0°C). The memory function stores and recalls up to 25 labeled readings.
Self diagnostics display codes help users troubleshoot electrodes, buffer, and temperature errors. The measurements are automatically or mannually temperature compensated, and the meter is calibrated at a 5 point buffer recognition (1.68, 4.00, 7.00, 10.00, 12.45) with adjustable values. An audible beeper will sound when a function is completed.

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.
