EK80 Water Column Sonar Data Collected During GU1903

C. Operating Area (include optional map/figure showing op area) Western Atlantic along the U.S. Mid-Atlantic Coast, cross-shelf, through Gulf Stream, out to blue water. Operations will be conducted in and around York Bight, Long Island Sound and Cape Cod. Gulf Stream eddies will be sampled along the way. Plan includes sampling transient features present in the region at the time of the cruise. Cruise begins in Norfolk, VA and will end in Norfolk, VA, US. Tentative cruise track (Fig. 1) is shown below along with daily locations in Table 1. Cruise track will be adjusted to maximize characterization of processes and features present during time of cruise. In addition, one of the issues with our work is that we need cloud free skies to maximize our work. We will be working with the crew to make adjustments to the cruise track daily. D1. VIIRS Cal/Val Objectives Observe and measure inherent and apparent optical properties of water masses for three primary objectives: 1) JPSS VIIRS ocean color satellite validation; 2) Inter-calibration and intercomparison of validation techniques and measurements; and 3) optical characterization of ocean variability (i.e. coastal, near-shore, cross-shelf, eddies, fronts, filaments, blue water).
