The Extech Temperature & Humidity Datalogger Kit is a compact system that that logs data for days, weeks, or months.The meter collects humidity readings from 0 to 100% RH and temperature from -40 to 185 ̊F (-40 to 85 ̊C).  It can log up to 16,000 readings (8,000 each temperature & humidity) all in a waterproof housing. Multiple dataloggers can be programmed and data downloaded from one single docking station.The dock easily connects to a PC via the included RS-232 cable (or optional USB cable) and data can be further analyzed with the included Windows compatible software.

 

Programable sampling rates can be set from 1 second to 2 hours and high/low limits with alarm indication. The logger can be programmed and data stored and analyzed using the software. Three start methods are conviniently available: scheduled, immediate, or magnetic. The real time clock stores date and time with the data.

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.
