Overview
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.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute

Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.
