Program goals

To elucidate marine microbial community diversity, function and interactions between food web components as it relates to biogeochemical cycling in the ocean.

Brief Description

Marine bacteria comprise about 80% of open ocean biomass, remineralize most organic matter into inorganic forms (which are then bioavailable to phytoplankton), and play crucial roles in most elemental cycles. Marine viruses infect and kill bacteria, phytoplankton, eukaryotic microorganisms and metazoa, and in doing so influence the overall biogeochemical cycling of the ocean.

Hence, viral activities in the ocean are directly linked to ocean-atmosphere fluxes. Research in the marine microbiology laboratory focuses on the biogeochemical impacts of marine viruses on communities of microorganisms, and understanding how variability in the composition, function, and interactions between components of pelagic microorganisms relates to ecosystem-scale processes.
