This page lists of a few source of information describing the known status of ocean observations of parameters describing the Particulate Matter EOV. Overview of current biogeochemical profiling floats with backscatter and fluorometer sensors is provided by OceanOPS. For an overview of sattelite-derived estimates of chlorophyll-a, particulate inorganic carbon or particulate organic carbon, among other relevant parameters, please see the ESA OC-CCI portal (https://www.oceancolour.org) or NASA OceanColour Web (https://oceancolor.gsfc.nasa.gov).
Below are a few recent snapshots with current Biogeochemical Argo and OceanGliders global coverage, and snapshots or annual composite images of Chl-a, PIC and POC derived from ocean colour radiometry measurements.
