OB34C:
From the Twilight Zone to the Troposphere: Ocean Optics Applications to Biogeochemical Cycling in and Through the Surface Ocean III Posters

Session ID#: 93478

Session Description:
Advances in remote sensing and in situ ocean optics technology have led to new interdisciplinary studies examining the connections between planktonic community structure and biogeochemical cycles, such as NAAMES, EXPORTS, and COMICS. Applications of hyperspectral reflectance, absorption,scattering, multichannel backscattering, and laser diffraction and particle imaging and sizing can yield in-depth information on phytoplankton and other particles in the water column, allowing for development of algorithms targeting next generation of Earth observing satellites (such as NASA’s Plankton, Aerosol, Cloud and ocean Ecosystem mission - PACE). In this session we invite contributions from studies using ocean optics tools from shipboard, autonomous, airborne, or remote sensing platforms coupled with biogeochemical parameters to study connections between the surface ocean and the atmosphere or the surface ocean and the mesopelagic, including assessments of net community production, food web dynamics, export production and flux, ocean-to-atmosphere fluxes of aerosols and trace gases of biological origin.
