Oceanographer
University of Washington, School of Oceanography


Eric Olson has been an Oceanographer at the University of Washington for almost 27 years. He holds a technical position working with Dr. Marv Lilley on a number of chemical and biological oceanographic projects. Their focus of the last 22 years has been the study of dissolved gases in hydrothermal vents. They have been involved in both exploratory work to discover vent systems and collected samples from high temperature hydrothermal vent systems from all over the world. They have used specialized "gastight" titanium samplers on Alvin (HOV), Jason, ROPOS and Tiburon (ROVs), and now Quest, to collect samples from the North and South Pacific, the Mid-Atlantic Ridge and the Indian Ocean. With this cruise, Eric hopes to obtain samples from the Lau Basin vent site (collected by John Lupton), which he anticipates to be very different in chemistry. Additionally, he will do ship-board analysis of hydrogen and methane in samples collected in “plume surveys” done with the CTD package as the team examines seafloor activity over a broader/regional scale.
