Abstract

Ocean color remote sensing repositories store critical environmental information about our planet. As the impacts of climate change intensify in coastal and inland water bodies, effective utilization of remote sensing platforms is essential for environmental monitoring and real-time decision-making. Thus, this dissertation research develops, validates, and applies a remote sensing product for water clarity, an overall parameter of water quality. I investigate the impacts of individual sensor configurations on water clarity satellite products and evaluate statistical modeling approaches for bridging historical and present-day ocean color remote sensing platforms. This evaluation then informs the development and global validation of a new cross-sensor water clarity product. Finally, I apply this new product to the Stellwagen Bank National Marine Sanctuary to document multi-decadal water clarity change. Altogether, the effective utilization of ocean color data by this new water clarity product improves our spatial and temporal understanding of coastal and inland water quality change.
