Relating Ocean Optics to Photochemical Transformations of Dissolved Organic Carbon in Coastal Waters

Abstract

LONG-TERM GOALS. The long-term goal of this research is to use remotely sensed ocean optical data for estimates of the regional and global scale significance of photochemistry to dissolved organic carbon (DOC) cycles and optical changes resulting from these processes. OBJECTIVES. The central objective of this research program is to examine quantitatively the links between optical measurements and photochemical carbon transformations in the sea. Our goal is to establish quantitative methods to relate variability in water-leaving radiance to photochemical reactions that lead to direct loss of colored dissolved organic matter (CDOM) and consequent changes in UV optical properties in the photic zone. By examining these quantitative relationships, we also hope to gain both an understanding of the dominant variables controlling UV optics in the mixed layer and the critical parameters influencing DOC photochemical reactions in seawater.
