Description:The sixth NOAA-dedicated JPSS VIIRS Ocean Color Calibration/Validation Cruise was successfully conducted in the Gulf of Mexico in early 2021 when COVID-19 still threatened our society's health and safety. The NOAA Ship Gordon Gunter provided ship time and logistic support, and nine scientists, including one student, participated in the field campaign. It sailed off from Pascagoula, Mississippi, on April 20 and concluded in the same port on April 29. A total of 33 stations were occupied during the cruise, with continuous observations of ocean physical, optical, biological, and biogeochemical parameters along the ship tracks. At stations, the participating teams measured apparent optical properties and inherent optical properties, including remote sensing reflectance, diffuse attenuation coefficient, polarization (Stokes vector), light absorption and backscattering coefficients, phytoplankton cell counts, and fluorescence. Water samples were also collected and treated onboard to analyze phytoplankton and CDOM light absorption coefficients and suspended particulate matter. Preliminary in situ and satellite matchup data were constructed to validate VIIRS ocean color sensors onboard SNPP and NOAA-20.
