BioGeoChemical-Argo float data including bio-optical profiles and POC flux at 1000m in the Southern Ocean from 2014 to 2019.

These datasets contain measurements from BGC-Argo floats equipped with a transmissometer and which cover the Southern Ocean from 2014 to 2019. The first dataset ("profile_data.csv") includes bio-optical profiles of the particulate backscattering coefficient (BBP in m-1), the concentration of Chlorophyll-a (CHLA in mg m-3), and the particulate beam attenuation coefficient (CP in m-1) with data processing and quality control described in the manuscript entitled “BioGeoChemical-Argo floats reveal stark latitudinal gradient in the Southern Ocean deep carbon flux driven by phytoplankton community composition” submitted to Global Biogeochemical Cycles. In the second file (i.e. "flux_1000m.csv"), we provided attenuance fluxes (in day-1) at 1000m measured by the transmissometer acting as an Optical Sediment Trap. These flux values were then converted to POC fluxes (mg POC m-2 day-1) with the method described in the submitted manuscript.  Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
