Abstract:The objective of this Letter is to introduce a concept for identifying marine provinces by applying two band ratios that are indicative of chlorophyll distribution patterns. The ratios of water-leaving radiances 443?nm/551?nm and 678?nm/ 667?nm are close to the two absorption bands of chlorophyll; however, as photon penetration depth at the applied wavelengths varies, each ratio responds to different depths. This allows a qualitative interpretation of separated clusters in scatter diagrams. Pattern classification separates the major biogeochemical provinces as documented with the Peruvian upwelling system and the convergence zone in the Brazil–Falkland/Malvinas current system.
