AB: As part of an ongoing effort to optically characterize the Chesapeake Bay in an effort to develop regional remote sensing ocean color algorithms, the Marine Optical Characterization Experiment (MOCE) team sampled the middle portion of the Chesapeake Bay in an effort to document and characterize a high-sediment, fresh water plume cascading down the Bay following record breaking rainfall totals in the Chesapeake Bay Watershed during the summer of 2006. These plumes can have potentially devastating effects on the Chesapeake Bay's fragile ecosystem by increasing nutrient loads, depositing sediments, and decreasing salinity and light levels. Sampling took place from July 5th through July 7th spanning the front of the advancing feature. Measurements of total suspended matter, chlorophyll a, chromophoric dissolved organic material absorption, and hyperspectral optics were collected. The optical measurements included above water surface irradiance (Es), in-water downwelling irradiance (Ed) and in-water upwelling radiance (Lu). From the optical measurements we can derive water clarity (K490), normalized water-leaving radiance, and remote sensing reflectance. These parameters will better enable the detection and tracking of these types of events in the future utilizing remote sensing techniques.
