Tamara Baumberger is a marine geochemist at the Oregon State University and at the National Oceanic and Atmospheric Administration (NOAA) in Newport, OR. She received her Ph.D. from ETH Zurich in Switzerland and completed postdoctoral work at the University of Bergen in Norway and at NOAA PMEL in Newport, OR. Her research focuses on the gas chemistry of hydrothermal vents and methane seeps with a special interest into the carbon cycle and noble gas chemistry. Tamara has participated in more than 20 research cruises including two ROV cruises visiting methane seep sites at the Cascadia Margin. Tamara serves as a principal investigator during the “Observing Seafloor Methane Seeps at the Edge of Hydrate Stability” expedition. She will be collecting gas bubbles released from the seafloor along the Cascadia Margin and study their chemical composition and implications for methane seep sites.
