Abstract
Quantitative distributions of major functional PFTs of the world ocean improve the understanding of the role of marine phytoplankton in the global marine ecosystem and biogeochemical cycles. Information on the attenuation and light penetration depth tells us the extend of phytoplankton primary production and until which depth satellite obtain information on ocean colour. \nIn this study, global ocean color satellite products of different dominant phytoplankton functional types' (PFTs') biomass and the vibrational Raman scattering (VRS, i.e. the inelastic light scattering at water molecules, for different wavelength ranges retrieved from hyperspectral satellite data of the satellite sensor SCIAMACHY (SCanning Imaging absorption spectrometer for Atmospheric ChartographY on board ENVISAT, operating 2002-2012) using Differential Optical Absorption Spectroscopy applied to phytoplankton (PhytoDOAS) are presented (see also Vountas et al. 2007, Bracher et al. 2009, Sadeghi et al. 2012a).
