Viruses and Nutrient Cycles in the Sea

Abstract
Few of us may ever live on the sea or under it, but all of us are mak-ing increasing use of it either as a source of food and other materi-als, or as a dump. As our demands upon the ocean increase, so does our need to understand the ocean as an ecosystem. Basic to the un-derstanding of any ecosystem is knowledge of its food web, through which energy and materials flow. (Pomeroy 1974, p. 499)
