Abstract: Long Island Sound (LIS) estuary is dynamic in space and time, with biogeochemical transformations occurring from anthropogenic, river, and marine sources, with tidal, seasonal, and interannual variability. Colored dissolved organic matter (CDOM) is both a tracer of these processes, and an integral component that impacts carbon cycling, nutrient cycling, hypoxia, light penetration, and water color. This research represents the first analysis evaluating atmospheric correction techniques for Landsat-8 in LIS based on an extensive dataset of above-water radiometry in and around LIS waters. Secondly, using a robust dataset of CDOM absorption from in situ water samples collected in LIS, algorithms for retrieving this parameter fromLandsat-8 remote sensing reflectance are evaluated. This research provides preliminary results and a framework for continued analysis on the use of high spatial resolution ocean color satellite sensors in LIS for retrieving CDOM, and ultimately dissolved organic carbon (DOC). This will allow for monitoring CDOM and DOC across the river-estuary interfaces of LIS dating back to 2013(launch of Landsat-8), which will contribute to a better understanding of the controls on LIS carbon cycling and water quality.
