There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Bluejeans link for the seminar is available here.

The ocean covers most of Earth’s surface and plays a crucial role in global biogeochemical cycles. Phytoplankton growing in the open ocean surface account for approximately half of all annual carbon fixation. Therefore, we need a robust accounting of the drivers of phytoplankton growth and mortality, particularly their responses to changing environmental regimes, in order to model the Earth’s carbon cycle. The new flood of insights molecular technologies have provided into marine microbial adaptations to the hostile and nutrient-bereft open ocean surface calls for a fresh look at the role of dynamical ecosystem models in microbial oceanography. Here we will cover a few vignettes exploring (1) the response of the entire microbial ecosystem to the day/night cycle, linking physiological changes to bulk ecosystem properties, (2) the coevolutionary dynamics between a phytoplankton host and its virus under nutrient limiting conditions, adding theory to the proposed ‘Ferrojan Horse Hypothesis’, and (3) preliminary progress on fledgling work seeking to understand the role of viral infection in organic particle formation and export.
The seminar will be hosted at this bluejeans link.
