Thermo Orion AQ4000 colorimeter has the Auto-ID feature that automatically identifies the species to be measured, selects the program and initiates the measurement without the user ever having pushed a button! The AQ4000 with its Auto-ID and pre-programmed methods ensure error-free readings at a very affordable price.

This rugged and attractive unit is waterproof to IP67 standards. The AQ4000 is so advanced, a user can customize a calibration and create a completely custom method. Up to 12 data points can be used to define a custom method and a maximum of ten methods can be stored in the colorimeters memory. The simple operation guides a user through the setup and measurement.

Selection of display units is a button press away. Selectable measurement units include concentration, absorbance or percent transmittance. Datalog 100 points in the field with a time and date tag, then download to a printer or computer in the lab. The AQ4000 carries a two-year warranty.

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.
