Overview
The PME miniDOT Clear Dissolved Oxygen 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.

Data Collection
The oxygen sensor is an optode that measures dissolved oxygen concentration in water through a fluorescence method. 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.

Questions & Answers
How long does the battery last on the miniDOT logger with a miniWiper installed?
The miniWiper has its own battery and can operate for up to 3-months at 1-hour wipe interval. There are some effects on the battery in colder/deeper environments, which is further discussed in the manual: PME miniWIPER for miniDOT Logger Manual.

Long-Term Monitoring in the Chautauqua Lake Watershed

With a widely developed shoreline, Chautauqua Lake experiences influxes of non-point source pollution that have historically impacted the health of the lake. The Chautauqua Lake Association (CLA) has been monitoring the lake for over two decades, reporting on changes that have occurred over the years. A pair of local lake advocates, Jane and Doug Conroe, have lived on the lake for over 40 years and have played an important role in establishing monitoring programs and facilitating consistent data collection throughout the watershed. Doug has been involved with the Chautauqua Lake Association (CLA) since the pair moved to the area in 1980, and is currently serving as the Executive Director.

No Red Herrings: Data Driving the Largest Salt Marsh Restoration in the NE USA

The Herring River system encompasses around 1,000 acres in the Towns of Wellfleet and Truro, Massachusetts. In 1909, the Chequessett Neck Road dike was built at the river’s mouth, drastically limiting tidal flow. Today, it’s one of the most restricted estuaries in the northeastern United States. As a result, the area has suffered environmental decline, including poor water quality, hypoxia, lower pH, and salt marsh degradation. In 2023, the Town of Wellfleet received $14.7 million from NOAA’s Office of Habitat Conservation to fund the Herring River Restoration Project (HRRP). Francesco Peri, President and CEO at Charybdis Group LLC, uses a network of NexSens data loggers to monitor water level and water quality on the Herring River.

Carbon and Nutrient Monitoring in the Great Lakes Using Satellite Observations

Carbon and nutrients are the foundation of lake food webs and play an important role in the chemical and physical processes that shape aquatic ecosystems and various lake dynamics. Studying these cornerstones can help improve understanding of other lake conditions like harmful algal blooms, hypoxia, and phytoplankton community composition. The way in which these characteristics are monitored varies, though many rely on a proxy approach wherein parameters are extrapolated from the measurement of a different parameter. An assistant professor at Cleveland State University, Brice Grunert, is working to improve current strategies and take a satellite approach to monitoring the Great Lakes.
