Scripps marine biologist Michael Latz and his graduate students are studying the effects of fluid motion on single-celled algae known as dinoflagellates, one of the single most common sources of bioluminescence at the surface of the ocean. Bioluminescence is light produced as a result of a chemical reaction within specialized structures in the dinoflagellate cell.

The coastal intertidal zone is the area between the low and high tide zones that is not quite oceanic and not quite terrestrial. It is a unique and vibrant ecosystem linking land and sea. Graduate students in the laboratory of biological oceanographer Lisa Levin study these the natural processes of these environments and the impacts humans have on them. These students believe their work will have practical application on management of San Diego wetlands.

This feature is the third in a continuing series celebrating the100-year history of Scripps. In it, Scripps’s growth during World War I and throughout the early1920s are detailed. The first Scripps pier was completed, William E. Ritter, the institution’s director, and his wife, Mary, were settled into their home on the campus, and Francis Sumner received support to study environmental influences on heredity in a genus of field mouse. This area of research, although seemingly a departure from marine science, reflected the importance of understanding an organism in relation to its environment—a principle espoused by Ritter.
