The miniDOT Clear logger is a completely submersible instrument that logs dissolved oxygen and temperature measurements with an internal LCD screen for accessing the latest readings. It includes an optical DO sensor, a temperature sensor, batteries and a micro SD memory card. Data are recorded internally with a sample interval from once per minute to once per hour and can be offloaded to a computer via USB cable.

The miniDOT sensor is an optode that measures lifetime-based luminescence quenching of a thin membrane. The sensing foil contains a coating that has a variable fluorescence that depends upon oxygen concentration in the surrounding water. The sensor is able to compute oxygen concentration in mg/L and record these measurements internally. Each logger is factory-calibrated at 12 oxygen concentrations each at 8 temperatures for a total of 96 calibration points.

Restoration, Testing, Research and Education

A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek. As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow. Much of the original property and surrounding land has fallen prey to urban sprawl.

Storms Cause Extended, Elevated Contaminant Concentrations in Urban Streams

Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die. Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn. This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area. “‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters. This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.

A Nationwide View shows “Evolution” of Water Quality Concerns

Water quality issues are shifting in the United States’ rivers in big ways. Those changes are driven, in part, by the way the land in a watershed is used and they’re big enough that researchers may need to change the way they think about water quality in the American rivers. “What was striking to us was how perceptions of water quality issues from several decades ago may need to be updated,” said Edward Stets, a U S Geological Survey research ecologist, in an email response to questions from Environmental Monitor. New research by Stets published in Environmental Science & Technology in March highlights these shifting water quality issues.
