ESTABLISHING A CULTURABLE HOST/BACTERIA SYSTEM TO EXPLORE INTERACTIONS OF SOUTHERN OCEAN DIATOMS AND BACTERIA WITHIN THE PHYCOSPHERE
Marine phytoplankton and bacteria impact global biogeochemical processes, including global net primary productivity (NPP), carbon sequestration, silica sequestration, nitrogen availability, and oxygen production. In the Southern Ocean, phytoplankton growth is limited by light and the availability of...
