frits as the junction between the reference half-cell and the sample. The porous material rapidly clogs with precipitated silver chloride, causing unstable junction potentials. The Flat-End pH Electrode uses a double junction reference half-cell with a free-flowing outer reference junction. The free-flowing junction provides nearly constant junction potential, greater accuracy and reliability than conventional porous junction electrodes, and is ideal for both routine and demanding applications.
The Flat-End pH Electrode contains a silver/silver chloride element in an inner chamber that contacts the electrolyte solution at an inner junction. Electrolyte flows from the free-flowing outer
junction at the electrode tip. This design makes it ideal for use with samples containing sulfide or other substances.
This Hach electrode uses a flat glass membrane that can be used at temperatures of 0 to 45 C, hydrates easily, and has durability at high temperatures. A moderate sodium error occurs at pH levels greater than 12.

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.

New Technologies Reducing Uncertainty in Estimation of River Flow
Some of the most interesting data in the world of river and stream monitoring come at times when it's practically impossible to capture—during extreme weather events, for example. Timing alone makes capturing unusual events a challenge, and these kinds of issues have prompted researchers to use classic monitoring data along with new technologies to develop and improve hydraulic modeling for estimating river flows. Steven Lyon , a Conservation Scientist with The Nature Conservancy, Professor at Stockholm University and Associate Professor at The Ohio State University, spoke with EM about the research .
