Environmental Protection Agency researchers aboard the Lake Guardian visited Put-in-Bay this week. Their visit included a stop at Stone Laboratory on Gibraltar Island.
“The R/V Lake Guardian conducts sampling surveys on all five Great Lakes during both the spring (late March, after ice break-up) and summer seasons. The spring survey monitors lake health during a time of low biological activity, when the lakes are well-mixed. The summer survey monitors lake health during the season of high biological activity, when the lakes are stratified. During these surveys, water, plankton and benthos samples are taken at designated stations throughout each lake. These monitoring surveys have been ongoing in the lakes since 1983, resulting in an exceptional long-term monitoring dataset for evaluating the health of the Great Lakes ecosystem through time.”
