GSO scientists characterize the genetic diversity and distribution of planktonic populations globally over time, space, and in different marine ecosystems. This provides an understanding of basic processes of speciation, selection, and adaption, and how plankton respond to their environments.

Examining physical influences on phytoplankton form and function shows how small-scale turbulence affects cell and colony morphology in diatoms.

Deep-sea biologists study the distribution, diversity, and biogeochemical consequences of microbes in marine sediment, including their potential as a source of new antibiotics.

GSO scientist research also documents the adhesion sequences of micro- and macro-fouling communities on submerged surfaces to understand and predict responses of different types of material to exposure in seawater.
