Overview
The Hach pH unique color disc kits feature a continuous-gradient color wheel for fast, accurate comparisons. The continuous color provides higher levels of accuracy. Kits also use a blank as a reference in color comparison, compensating for color in the sample.
Mechanics
Simply react the sample, then insert the blank and the sample into the holder. Rotate the color wheel to obtain a color match between the blank and the reacted sample. Accuracy for color disc kits is typically +/- 10% or +/- the smallest increment, subject to individual color perception.

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.

Sustainable Fishing in Alaska: Protecting the Salmon Capital of the World through Research
In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.
