Quantifying Carbon Export Pathways in the Global Ocean
Session ID#: 85783
Session Description:
The ocean's biological pump connects the surface ocean, where light-driven photosynthetic processes fix dissolved carbon dioxide, to
the ocean’s twilight zone, where exported carbon is consumed and transformed by a myriad of biological and physical processes as it transits to depth. Three basic pathways are thought to control organic carbon export in the open ocean - gravitational sinking, active migration by metazoans and physical advection and mixing - which are driven by a complicated combination of ecological, biogeochemical and physical oceanographic processes. Developing a predictive understanding of these export pathways and their attenuation with depth is critical for diagnosing present and future rates of ocean carbon sequestration. Recent advances in genomics, in situ particle
imaging, remote sensing, geochemistry, autonomous sampling tools, along with recent investments in comprehensive interdisciplinary field programs like EXPORTS, COMICS, GOCART, CUSTARD, and WHOI’s Ocean Twilight Zone makes achieving this goal possible. This session will highlight research that couples ecological, biogeochemical, and physical observations and modeling aimed at improving our understanding and quantification of the ocean’s biological carbon pump.
