Sometimes Great Lakes science is done in very unusual conditions, like a mayfly hatch on #LakeErie! EPA and University of Minnesota-Duluth co-operate the Great Lakes Sediment Surveillance Program, which monitors the spatial distribution and temporal trends of persistent, bioaccumulative, and/or toxic chemicals in sediments of the Great Lakes. To make the research vessel #LakeGuardian a less attractive destination for the mayflies and keep them from landing in the sediment samples being collected, scientists from University of Minnesota-Duluth and EPA worked under red light. Although a bit of a nuisance, mayfly hatches are also indicators of Lake Erie’s health because mayfly populations provide a valuable food source for fish and birds. Fun fact: Mayfly swarms can appear as rainstorms on Doppler radar!
