Michael Stoddard Henry was a Staff Scientist who passed away on May 9, 2018, after years of dedication to advancing many of Mote’s highest priority studies in the field of ecotoxicology. Mike's dedication to his work was complemented by his unconditional friendliness, humor, positive presence and love of his family and friends.
Since Mike joined Mote as a Staff Chemist in 1987, his efforts have been essential to the institution's field and lab studies on the fate and effects of toxic substances impacting marine species and ecosystems critical to Florida and the planet. Mike thrived at Mote and took on new roles of increasing impact, ultimately serving as a Staff Scientist in the Ecotoxicology Program. All the while, he powered Mote's progress toward numerous key discoveries, particularly in the Lab's efforts to understand and respond strategically to the challenge of Florida red tide
Mote's Ecotoxicology Program assesses what toxic substances are found in the marine environment, their sources, fate and effects. Mike was involved with extensive field studies backed up by controlled laboratory studies that addressed chemical changes and metabolic products produced by marine organisms exposed to toxins. A major focus of the program has been the analysis of natural biotoxins and pesticides in water, air and marine animals, providing information required to understand how marine life and humans are exposed to biotoxins and in what amounts.
