Jack Barth is a professor of oceanography in Oregon State University’s College of Earth, Ocean, and Atmospheric Sciences. He received a Ph.D in Oceanography in 1987 from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution Joint Program in Oceanography. Jack’s research seeks to understand the spatially and temporally variable circulation, water mass structure and ecosystem response in coastal waters. He has led a number of research, technology development and ocean observing system projects off Oregon and the Pacific Northwest. Jack participated in the Global Ocean Ecosystems Dynamics (GLOBEC) Northeast Pacific and the Coastal Ocean Processes (CoOP) research programs, including serving as Chief Scientist on many interdisciplinary research cruises. His present research includes a focus on the characteristics and formation of low-oxygen zones off Oregon. Jack’s research team uses autonomous underwater gliders to study this region, logging over 49,000 km of measurements over the last several years. He presently serves on the Oregon Ocean Policy Advisory Council’s Scientific and Technical Advisory Committee. From 2004 to 2007, Jack was a member of NSF’s Observatory Steering Committee that launched the OOI and, together with Collier and Dever, was co-PI on the original OSU proposal to establish the Endurance Array. As Project Scientist for the OOI, he is responsible for facilitating the scientific use of the Endurance Array and working with the OOI engineering team to ensure the observatory infrastructure will meet the OOI science objectives.
