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.

本数据集包含自2014年至2019年期间，搭载透射计的BGC-Argo漂流浮标在南大洋的测量数据。其中，第一份数据集（“profile_data.csv”）包含了生物光学剖面数据，包括颗粒后向散射系数（bbp，单位为m-1）、叶绿素a浓度（chla，单位为mg m-3）以及颗粒束衰减系数（cp，单位为m-1），其数据处理与质量控制过程已在《生物地球化学Argo漂流浮标揭示由浮游植物群落组成驱动的南大洋深层碳通量显著的纬度梯度》一文中详细描述，该文已提交至全球生物地球化学循环期刊。第二份数据文件（即“flux_1000m.csv”）提供了由透射计作为光学沉积陷阱测量的1000米处的衰减通量（单位为day-1）。随后，这些通量值根据提交的论文中描述的方法转换为POM通量（单位为mg poc m-2 day-1）。
