Details
The miniDOT logger is a completely submersible instrument that logs dissolved oxygen and temperature measurements. 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.

Eel Excitement: At Hudson River NERR, Environmental Monitoring Takes A Slippery Turn
“I remember how I first became fascinated with eels,” says Chris Bowser, Education Coordinator for the Hudson River National Estuarine Research Reserve (HRNERR) and Hudson River Estuary Program (HREP) of the New York State Department of Environmental Conservation, in partnership with Cornell University’s NYS Water Resource Institute . “I was doing a talk on a ship called the Clearwater. There was a trawl net catch on the deck and I picked up one of the things in the catch. It was a piece of trash, a plastic toy truck with barnacles growing on it. I was speaking to the audience and they seemed really riveted! I was thinking, ‘I must be giving a really good talk.

Washington Leading on Water Quality with New Winery Permit
In 2014, the Department of Ecology (DOE) in the State of Washington began to work on water quality standards related to wineries in the Yakima Valley and the rest of the state. The specific concern is the handling of wastewater from winemaking; this kind of wastewater is toxic. Water into wine, and waste Winery wastewater is high in sugar and filled with suspended solids such as grape plant matter and juice. Microbes can digest those solids, but only if there's enough oxygen in the water. In wastewater from winemaking, there isn't enough oxygen for those microbes—biochemical oxygen demand (BOD) far exceeds supply. Consider this. To use the wastewater for irrigation , BOD must be below 50 .

Meet The Stream Team: MVUUF Citizen Scientists Keep A Watchful Eye on Dayton’s Wolf Creek
Named for wolves that were once spotted in the area during the pioneer era, Wolf Creek of Dayton, Ohio is a waterway nearly 20 miles long, a southeast flowing tributary of the Great Miami River. Wolf Creek is one of the “five rivers” referred to in the name of Five Rivers MetroParks- - Dayton, Ohio’s premier park system. Five Rivers MetroParks was founded in 1963 with the goal of preserving green space for future generations. The “five rivers” in its name refer to the Miami River, Stillwater River, Mad River, Twin Creek and Wolf Creek which run through the region. The area has many citizen scientist volunteers that help assess water quality in selected areas.
