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

Greg BrittenWhere Do All the Phytoplankton Go?
Approximately 50 gigatons of organic carbon are produced annually via marine primary producers (mainly phytoplankton) - roughly equal to the production of plant matter on land. But where does all the organic matter go?
I track the fate of marine primary production via two pathways. The first is 'export' production where a fraction of primary production is exported vertically from the surface ocean and sequestered in the ocean interior. The second is the trophic pyramid where primary producers are processed through higher trophic levels, ultimately fueling global fisheries. These pathways have significant implications for human well-being and will be impacted by climate change. I discuss progress towards understanding these pathways and their trajectories into the future.
