After checking the weather and deciding where to go, it is time to board the Neeskay and cruise out onto Lake Michigan.
Cruises can last anywhere from 6 to 15 hours depending on where we are going and how much sampling needs to be done.
Below are the sampling tools we use during a cruise. While not every tool is used on each cruise, they all play an important role in helping us collect samples for further analysis when we return to the lab.
