NCEO Particulate Organic Carbon estimates from quality-controlled BGC-Argo data (2010-06-01 to 2021-09-22), V1.0
This is an in-situ dataset of estimates of particulate organic carbon (POC) based on all the current (2021-09-22) profiles of optical backscattering (BBP) collected by (BGC)Biogeochemical-Argo floats. The dataset spans from 2010-06-01 to 2021-09-22 and covers the upper 2000 dbars of the water column (continuous profiles have been binned in 41 vertical bins). The dataset was produced by first devising a new set of automatic tests to quality control the large BBP dataset available (>31M records over >130k profiles). The QCed BBP was then converted into POC using an empirical algorithm (average of the POC: BBP slopes of Cetinic et al., 2012)

Data were produced by the project team and supplied for archiving at the Centre for Environmental Data Analysis (CEDA).
BBP data have been quality controlled to the best of PML's current capabilities. Conversion to POC is based on an empirical algorithm derived in the North Atlantic and therefore is expected to be affected by uncertainties of (100%)
Computation for Particulate Organic Carbon estimates from quality-controlled BGC-Argo data
The POC estimates were produces using an empirical algorithm (average of the POC:BBP slopes of described Cetinic et al., 2012. Details of algorithm and input BGC Argo data can be found in the documentation section.
