Summary: The function of the ocean is governed by microscopic organisms, including bacteria and phytoplankton. Oceanographers typically consider the ecology of these microbes across large ocean-scales, but their activities and interactions are defined at the scale of individual cells. This research will redefine our knowledge of important marine microbial processes by coupling novel physiological and molecular tools to resolve the microscale ecological links between bacteria and phytoplankton, and will identify how the chemical interactions between these groups change under shifting environmental conditions. This has significance for transforming our understanding of the factors that control the health and function of our important ocean ecosystems.
