On July 31, 2023, renowned limnologist Dr. Robert Evan Carlson passed away after his battle with Parkinson’s disease and multiple myeloma. Below is a statement by Princeton Hydro’s Senior Technical Director of Ecological Services, Dr. Fred S. Lubnow, who speaks for all of us at Princeton Hydro, on the legacy that Dr. Carlson left on the field of limnology.
“The field of limnology, and ecology in general, recently lost one of its greats with the passing of Dr. Robert Evan Carlson. His contributions to the fields of limnology and lake management were numerous, but he is best known for the development of the Carlson Trophic State Index (TSI). This is an internationally accepted protocol of assessing the health of lakes, ponds, and reservoirs that is used by everyone – from lake associations and ecological consultants to local, state, and federal governments – as a means of determining both declines in water quality due to increased nutrient loading and/or climate change, and improvements through watershed management and in-lake control measures.
As mentioned in his obituary, Dr. Carlson created the Secchi Dip-in, which is an annual summer event where volunteers measure the clarity of lakes throughout North America to develop a database on the overall health and status of our inland waterbodies. This program has grown to be a staple during Lakes Appreciation Month in July, and his tradition will continue on in every sample collected by volunteers.
As both a professor at Kent State University and an environmental consultant through his company Clearwater Environmental Consulting, Inc., Bob was an incredible source of information on measures to restore, protect, and preserve our aquatic ecosystems. On a personal note, I have met and spoken with Bob from time to time at the North American Lake Management Society’s annual conferences, and he was always willing to discuss and share his knowledge on lakes. Bob was always very friendly and generated a passion for freshwater ecology and management that was contagious. Bob will be sorely missed, but his legacy will live on as the TSI is widely used and the Great Secchi Dip-In continues in the future! Rest in Peace.”
A celebration of his life will be held on Saturday, November 4, 2023 at 2:00 PM at the Kent United Church of Christ, 1400 E. Main St. Kent, OH 44240. Donations in Bob’s memory can be made to the Dr. Robert E. Carlson Scholarship in Ecology and Evolutionary Biology at Kent State University. This scholarship offers stipends for students to travel to professional conferences, reflecting his passion for helping students in their studies and professional careers. Gifts to this scholarship fund can be made payable to The Kent State University Foundation and sent to The Kent State University Foundation, Attn: Gift Processing; P.O. Box 5190, 350 S. Lincoln St., Kent, Ohio 44242.
