Abstract

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)

Title

Computation for Particulate Organic Carbon estimates from quality-controlled BGC-Argo data

Abstract

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.
