This book provides results of spatial and temporal distributions of water quality parameters and marine primary production and its relationship with the driving atmospheric, ocean circulation and hydrobiological mechanisms established through a synergistic use of multi-spectral region spaceborne data and results of numerical model simulations of marine in-water and atmospheric processes related to the marine ecosystem. The changes in the studied marine/oceanic environments are analysed in light of recent climate change that imposes its influence through a set of forward and feedback interactions and forcing.
