The spatial detail of the OLI ocean color retrievals is well illustrated in Fig. 4, where the red, green, and blue products at 655, 561, and 443 nm, respectively, have been combined into a quasi true-color image. This image, collected on February 28, 2014, shows striking detail of the presence of suspended sediments and other optically active biogeochemical constituents around coastal landforms and where rivers enter the Bay. Sediment plumes, for example, are clearly evident offshore of the Potomac and Rappahannock Rivers despite February 2014 being an average year with regard to streamflow36 and free of any notable winter storms. The barrier islands between Hills Bay and Winter Harbor (between the Rappahannock and York Rivers) show significant suspended sediment loads, likely either from advective oceanward transport from the Rappahannock River or from wind-driven resuspension. Likewise, some of the shallowest areas of Chesapeake Bay, e.g., east of Smith and Tangier Islands, show substantial (re)suspended sediment loads. The high spatial resolution and relatively high SNR of OLI makes it possible to resolve the spatial structure of these estuarine features.
