Earth-Ocean Interactions contributes to a holistic understanding of marine ecosystems by exploration and research on hydrothermal vents, their impacts on the global ocean, and their unique chemosynthetic biological communities. This includes ecosystem characterization, resource assessment, environmental observation, and technology development. EOI is a collaboration of Oregon State University's Cooperative Institute for Marine Resources Studies (CIMRS), University of Washington's Joint Institute for the Study of the Atmosphrere and Ocean (JISAO) and NOAA PMEL.
