In this Review, the authors discuss the benefits of thinking about the ocean in terms of microniches and advocate the study of global processes on a microscale. Farooq Azam and Francesca Malfatti stress the need to study oceanic microbiologyin situand to use this as a unifying basis for modelling the influence of microorganisms on the structure of marine ecosystems. This might lead to new insights into the regulation of primary production and carbon cycling.
