Before coming to Brooklyn College, John F. Marra was a research scientist at Lamont-Doherty Earth Observatory of Columbia University from 1977 to 2007. In 2001, Marra was appointed associate director for the Division of Biology and Paleoenvironment at Lamont. While at Lamont, he was engaged in a variety of programs and projects in oceanography.
Education:
Ph.D., Dalhousie University - 1977 (Biological Oceanography)
B.S., Oregon State University - 1968 (Zoology)
Areas of Expertise:
Photosynthesis in the ocean. Marine phytoplankton, the microscopic marine plants that live in the uppermost, lighted, layer in the ocean, are subject to wind, waves, solar radiation and various kinds of motion and mixing. Marra is interested in how these various physical processes regulate photosynthesis and the growth of these marine plants, which, like trees, contribute significantly to the atmosphere's oxygen and also take up atmospheric carbon dioxide.
