R/V Lake Guardian Summer Water Quality and Biology Survey Gets Underway
From Sept. 3-17, scientists aboard the EPA Research Vessel Lake Guardian will conduct the 2021 EPA Great Lakes Summer Water Quality Monitoring Program and Biology Monitoring Program surveys on Lake Michigan, Lake Huron and Lake Superior. Scientists use nets, bottles, grabs, sensors and cameras to collect water, sediment and planktonic and bottom-dwelling organisms. This survey continues EPA’s 30+ year dataset of trends in Great Lakes ecosystem condition. Participating scientists on this year’s survey hail from:
• EPA Great Lakes National Program Office
• Cornell University
• Buffalo State University
• University of Minnesota Duluth
• University of Vermont
• Purdue University
• Oak Ridge Institute for Science and Education
The EPA Lake Erie and Lake Ontario survey stations will be sampled by our partners Environment and Climate Change Canada and Department of Fisheries and Ocean Canada using the Canadian Coast Guard Ship Limnos.
EPA’s Great Lakes National Program Office has conducted water quality surveys every spring and summer since 1983, except for 2020 when surveys were canceled due to COVID-19. These surveys help EPA fulfill environmental monitoring and assessment commitments specified in the Great Lakes Water Quality Agreement between Canada and the United States and in the U.S. Clean Water Act. The Lake Guardian is funded by the Great Lakes Restoration Initiative, launched in 2010 to accelerate efforts to protect and restore the world’s largest system of fresh surface water. For more information about EPA’s 2021 spring survey see EPA’s Floating Laboratory Lake Guardian Sails Again. This survey is the 4th Lake Guardian survey of the 2021 sampling season, with two additional Lake Guardian surveys planned for September and October 2021.
