Measuring only 88mm (3.46") in length and 18mm (0.71") in diameter, the Micro-Diver is the smallest Diver capable of accurately recording groundwater levels and temperature. The Micro-Diver is specifically designed for monitoring wells or drive-points too small to accommodate larger dataloggers. In addition to its compact size, the Micro-Diver’s memory capacity can store up to 48,000 measurements per parameter - almost one measurement every ten minutes for an entire year.

Van Essen Diver Loggers Join Fondriest Product Lineup
New to Fondriest Environmental’s product portfolio are the Van Essen Instruments Diver loggers, which are ideal for monitoring groundwater and surface water in a variety of applications. See below for a short description of each new addition. 
 
 Van Essen CTD-Diver Water Level & Conductivity Logger 
 
If you need to monitor groundwater levels and saltwater intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver is a good choice. It features a rugged, corrosion-proof ceramic housing and is equipped with a four-electrode conductivity sensor to measure electrical conductivity from 0 to 120 mS/cm. There are two options for measuring conductivity: true or specific conductivity at 25 degrees Celsius.

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.
Read MoreGar-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.
