Biography

Dr. John Vavrinec is a senior research scientist with the Coastal Assessment and Restoration technical group at the Marine Sciences Laboratory (MSL) in Sequim. Most of Dr. Vavrinec’s research has been basic science applied to fisheries or habitat management in coastal and estuarine areas around the country. He has been trained as a marine ecologist and oceanographer, and he has extensive experience conducting field studies. This research experience includes studies on crab foraging and predation, sea urchin demographics and community interactions, larval ecology and transport, settlement and recruitment of flatfish and invertebrates, macroalgal associations, fish movements and behavior, coral reef monitoring, and the use of marine protected areas. More recently his research has focused on coastal and nearshore restoration projects and the impacts of anthropogenic activities on wild populations. Much of this research has required cooperation with many interest groups including harvesters, state and federal managers, and other researchers, which has given Dr. Vavrinec a unique approach to the environmental issues of our waterways. Dr. Vavrinec is also a MSL Research Diver. Dr. Vavrinec has been certified since 1991 and has logged over 1000 scientific research dives. These dives have been conducted in a variety of locations, including the Gulf of Maine, Mid-Atlantic coast including Chesapeake Bay, Mexico, Turks and Caicos Islands, and the Pacific Northwest. He has conducted research in shallow coastal waters as well as deeper offshore areas, and has even participated in some blue water experiments. Operationally, Dr. Vavrinec has been a research diver with educational institutions, government organizations, and private companies. He has extensive experience in a variety of research methods and approaches that allow for resource assessment, construction of experiments, photographic/videographic documentation, and underwater inspections/maintenance.
