Correlation between MERIS and in-situ data for study of Pseudo- nitzschia spp toxic blooms in Galician coastal areas

摘要

Periodic blooms of Pseudo-nitzschia spp. in Galician coastal areas have caused virtual collapse of ecosystems with accompanying serious economic impacts. The aim of this work is the study of the physical environment of a coastal system correlating different bands of MERIS data with in situ Pseudo-nitzchia spp data provided by the Marine Environment Quality Control Centre (CCMM) during a study period associated to blooms of this specie related to coastal upwelling events (May-June 2003). This work tries to establish the foundations for the future development of algorithms for the study of the primary production and the identification of Pseudo-nitzshia spp toxic blooms in coastal waters case II making use of the great potential of the FR MERIS products, with high spatial and spectral resolution. The study is a part of the ESA project AO623, which is intended to study changing shorelines-beaches seasonally and annually, together with suspended matter discharged into coastal waters and pigments related to algae blooms.
