OB41B:
Linking the Biology, Geochemistry, and Circulation of the Gulf of Mexico I

Session ID#: 93141

Session Description:
The Gulf of Mexico is a small, dynamic marginal sea that supports a broad range of oceanographic environments, including eutrophic coastal systems, oligotrophic open ocean waters, hydrocarbon-impacted waters and sediments, and shelf waters that are susceptible to frequent harmful algal blooms. Large atmospheric, riverine, and submarine groundwater fluxes strongly influence the biogeochemistry of near-shore and open ocean waters, yielding a high degree of spatial and temporal variability. Several recent studies have focused on characterizing the biogeochemistry of the Gulf of Mexico using a range of interdisciplinary approaches. Following on a successful 2018 OSM Town Hall led by GEOTRACES and OCB, this session will bring together interested investigators to highlight new results from the Gulf and identify potential areas of common interest and collaborative opportunities to help inform future planning in GEOTRACES, OCB, and other relevant programs. We invite contributions that characterize the variability in the biology, geochemistry, and/or physical oceanography of the Gulf of Mexico, and especially the linkages between them. Suggested contributions may include, but are not limited to descriptions of water column and benthic geochemical distributions, biogeochemical rate measurements, characterizations of molecular ecology, geochemical fluxes, and descriptions of circulation that impact Gulf biogeochemical dynamics.
