Predicting Chromophoric Dissolved Organic Matter Distributions in Coastal Waters

Abstract

It is the long-term goal of this work to evaluate our understanding of CDOM sources and distributions in coastal waters by comparing high-resolution observations with four-dimensional, physical, chemical and biological models of the CDOM fields. 1.) Study freshwater CDOM endmember variability due to watershed and rainfall properties and seasonal cycling in detail in the Neponset sub-watersheds and by monitoring Hudson River (including several tributaries) and Neponset River endmembers. 2.) Use Geographical Information Systems (GIS) approaches to develop a predictive model of CDOM sources from terrestrial watersheds and groundtruth the predictive model in three watersheds of various sizes (Neponset River Watershed, Hudson River Watershed, Mississippi River Watershed). 3.) Compare our high resolution 4-dimensional measurements with the output of existing modeling efforts including Alan Blumberg's New York Harbor model. 4.) Incorporate biological and chemical processes into CDOM models including photochemical and biological modifications to CDOM distributions. 5.) Extend our predictive model to various estuaries to groundtruth the model and identify and quantify the key processes controlling CDOM distributions in coastal waters.
