Particulate Organic Carbon (POC) plays a vital role in the ocean carbon cycle. Though
relatively small compared with other carbon pools, the POC pool is responsible for large
fluxes and is linked to many important ocean biogeochemical processes. The satellite
ocean-color signal is influenced by particle composition, size, and concentration and
provides a way to observe variability in the POC pool at a range of temporal and spatial
scales. To provide accurate estimates of POC concentration from satellite ocean color
data requires algorithms that are well validated, with uncertainties characterized. Here,
a number of algorithms to derive POC using different optical variables are applied to
merged satellite ocean color data provided by the Ocean Color Climate Change Initiative
(OC-CCI) and validated against the largest database of in situ POC measurements
currently available. The results of this validation exercise indicate satisfactory levels
of performance from several algori.....
