| Activity | Sheina Marshall's career as a marine biologist led her to become a well known authority on two interrelated subjects: the physiology and life history of copepods (especially the genus Calanus), and the characteristics of marine productivity. Her long-term collaboration with the chemist A. P. Orr led to a series of publications concerning food chain relationships, the influence of changes in the physical environment on copepod populations, and the characteristics of photosynthesis in phytoplankton.
