Welcome new Bluesky folks! I'm Titus, an aquatic ecologist and fisheries specialist with Wisconsin Sea Grant. I work on all things #GreatLakes and freshwater from teaching 6th graders on a beach, surveying fish in a coastal wetland, or getting seasick on a commercial fishing boat! 🧪

Fisheries specialist Titus Seilheimer is unfazed by dead fish, but in late spring, he encountered one that gave him pause: a 4.5-foot sturgeon. It was an unlikely find. His mind churned; the questions kept coming. So, he decided to investigate. Read more: https://seagrant.wisc.edu/dead-sturgeon/

trends and variability are strongly associated with the Atlantic Multidecadal Oscillation, indicating a persistent ocean-atmosphere-lake interaction that modulates North American winter conditions.
