Overview
The PME miniDOT is a submersible instrument that includes an optical dissolved oxygen sensor, a temperature sensor, batteries and a micro SD memory card. Data is recorded internally with a sample interval from once per minute to once per hour and can be offloaded to a computer via USB cable.
Internal Storage
The miniDOT sensor is an optode that measures lifetime-based luminescence quenching of a thin membrane. The sensing foil contains a coating with a variable fluorescence that depends on oxygen concentration in the surrounding water. The sensor can compute dissolved oxygen concentration in mg/L and record these measurements internally. Each logger is factory-calibrated at 12 dissolved oxygen concentrations, each at 8 temperatures, for a total of 96 calibration points.

Researching Lake Erie’s Water Quality and Fisheries at the Fairport Harbor Research Unit
Lake Erie is well known for its sport fish populations and recreation on the water. However, the lake is also notorious for occasionally suffering from poor water quality conditions, such as harmful algal blooms and nutrient runoff . Nonetheless, millions of people flock to its waters every year to enjoy all that the lake provides. According to the Great Lakes Guide , Lake Erie is the most biodiverse of all the Great Lakes. Therefore, resources are poured into understanding Erie’s ecosystem, water quality, and wildlife. For example, the Ohio Division of Wildlife (ODOW) has several research units spread across the state, and one of them, the Fairport Harbor Research Unit, monitors the lake’s central basin.
Thirty Years of Data: Monitoring Water Quality in the Meduxnekeag River Watershed
The Meduxnekeag River flows right through the heart of Houlton, Maine and serves as a lifeline for the Houlton Band of Maliseet Indians , who have lived off the river for centuries. However, runoff from urban development and agriculture has led to declines in water quality and, as a result, the health of aquatic flora and fauna. These declines are of particular concern to the tribe, who has observed losses in native brook trout populations and shoreside vegetation growth and availability over the years. In response to this, documentation of water quality changes has been ongoing for three decades in order to record how conditions change in the larger Meduxnekeag River watershed.
Flow Photo Explorer: Studying Flows in the Penobscot River Basin
The flow dynamics of rivers and streams play an essential role in the chemical and physical functions of aquatic ecosystems. In Maine, varying flows in the Penobscot River Basin have impacted the health of the ecosystem, water resource use, and habitat suitability for native species—topics of particular concern to the Penobscot Indian Nation , who have been protecting and managing the waterway for millennia. Parts of the Penobscot basin have been monitored by the USGS stream gage network, which covers larger streams and rivers but excludes many of the small streams found on tribal lands.
Monitoring Aquatic Ecosystems: How Science Drives Waterway Management in Northwest Georgia
The University of Georgia is home to multiple labs that focus on monitoring aquatic ecosystems and organisms across the state. The River Basin Center connects these monitoring efforts with external partners, including government agencies and NGOs, to inform management and restoration of the state’s waterways. Phillip Bumpers is a Postdoctoral Associate in the Rosemond lab and the Wenger lab at the Odum School of Ecology and an affiliate of the River Basin Center. An aquatic ecologist, Bumpers’ research focuses on quantifying how environmental variability shapes aquatic ecosystems and understanding the drivers of these trends.
