Teaching Interests/Research:

Dr. Winn has extensive experience in real-world oceanographic research as well as marine science education. He has participated in numerous multidisciplinary oceanographic research expeditions involving research ships and scientists from a variety of academic centers throughout the world. He has spent more than four years at sea working on research projects funded by the National Science Foundation, the Department of Energy, and the National Oceanic and Atmospheric Administration. This work has included investigations of the biological and chemical impacts of deep sea hydrothermal vents using deep-diving research submersibles in the North and South Pacific as well as the Gulf of Mexico. In addition, Dr. Winn was instrumental in establishing the Hawaii Ocean Time-Series Program with funding from the National Science Foundation, and coordinated the biogeochemical component of that program from the early to late 1990’s in the North Pacific Subtropical Gyre. Furthermore, Dr. Winn was supported by the Department of Energy to conduct research on the World’s Ocean Circulation Experiment where he coordinated research cruises in the Pacific, the Atlantic, and the Indian Oceans. His current research is investigating the impact of changing ocean chemistry on the pristine coral reef environments surrounding the Northwest and main islands of the Hawaiian Archipelago, and he remains interested in exploring the changing carbon cycle in the subtropical North Pacific Ocean.

Dr. Winn also has extensive teaching experience in marine science. He works with Master’s level graduate students in HPU’s Master of Science in Marine Science program, and has taught chemical, geological, and physical oceanography at the graduate level. He also routinely teaches marine science courses at the undergraduate level  as well as courses in environmental science.
