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.

Questions & Answers
How does the miniDOT measure dissolved oxygen?

The PME miniDOT determines DO in water using an optode that measures flourescence.

What software comes with the dissolved oxygen logger?

The PME miniDOT includes free Java-based Windows software for configuration the logger and offloading data. The software will also compute oxygen saturation from the miniDOT logger measurements. A USB to micro USB cable is sold separately and required to communicate with the logger.

How long will the battery last?

With a 1-minute sample interval, the logger will remain powered for approximately 1-year.

Buoys in the time of Covid: Delays to important information

In early 2020, Michigan found itself facing one of the worst outbreaks of Covid-19 in the country. Though it’s close to second nature now, businesses, schools and governments were suddenly forced to conduct business without close contact. Universities and research institutions had to pause some scientific research. Whatever was able to continue slowed to a crawl. Around the Great Lakes, a network of buoys monitors dozens of water quality parameters and lake conditions, reporting them in real time. This year, the monitoring season was cut a bit short as Covid-19 restrictions hit in the weeks before buoys were set to be deployed.

Gar-Bage Fish No More. It’s Time to Respect Gar

Gar are a mean-looking fish, which along with their reputation as predators has earned them disregard and persecution for a long time. But that’s starting to change and it’s about time, says Solomon David, who’s watching with hope as gar are increasingly valued for their role in their ecosystems and as sport fish. “These attitudes are shifting, but there’s plenty of work to do,” said David, who is an assistant professor of biological sciences at Nicholls State University in Louisiana. While understanding of gar’s scientific and recreational value is increasing, gar still face the harmful effects of old beliefs and new challenges.

Hypoxic Conditions in Lake Erie Impact Yellow Perch Population

Yellow perch are a species central to the culture and economy surrounding Lake Erie. With the largest commercial fishery and a prolific sportfishing industry, Lake Erie's yellow perch are a treasured study subject for environmental scientists. Daily bag limits and other public wildlife regulations rely heavily on the work of scientists like Ann Marie Gorman, one of the Fisheries Biologists responsible for coordinating ODNR ’s Central Basin Bottom Trawl Survey.  The survey, ongoing since 1990, conducts seasonal assessments of the bottom fish community in Erie. It aims to index annual recruitment and catch-at-age of yellow perch.
