Marine heterotrophic bacteria are ubiquitous and abundant, occurring from the sea surface microlayer to the deepest ocean depths, at densities measured in millions of cells per milliliter of seawater. They are an essential component of the marine biota, contributing significantly to biogeochemical cycles of the major elements and representing a considerable proportion of microbial genetic diversity.
