{{short description|Marine geochemist}} '''Marta E. Torres''' is a marine geologist known for her work on the geochemistry of cold seeps and methane hydrates. She is a professor at Oregon State University, and an elected fellow of the Geochemical Society and the Geological Society of America.
== Education and career == Torres has a B.S. from the Universidad de Costa Rica (1976), and an M.S. (1983) and a Ph.D. (1988) from Oregon State University. As of 2022 she is a professor at Oregon State University.<ref>{{Cite web |title=Marta Torres |url=https://ceoas.oregonstate.edu/people/marta-torres |access-date=2022-03-15 |website=College of Earth, Ocean, and Atmospheric Sciences |language=en}}</ref>
== Research == Torres is known for her work at cold seeps and gas hydrates, geochemical tracers used to track fluid flow in seep environments, and the chemistry of sediments and porewaters.
