Wake Verification and Validation Study
Abstract
We propose an experimental procedure to measure and characterize the remotely sensed wake signature and the in situ relevant parameters of wakes left from passing ships and disturbances in open bodies of water. The main goal will be to provide initial validation data for a thermal mixing and renewal model, developed by Less, Chickadel, and Reinhardt[2017, ONR final report]. Our methodology was focused on large scale remote sensing using thermal infrared (IR), visible band (EO) together with in situ sampling of the surface warm layer. All of the remote sensing instruments are combined in the Compact Airborne System for Imaging the Environment (CASIE) and flown onboard a Cessna 182 light aircraft. In situ measurements were made via SWIFT drifters which included ocean temperature, turbulence, and air side meteorology data. We successfully collected four days of data in Dabob Bay within Hood Canal WA. These data were processed and delivered to our partner at NIWC for further analysis. We have also used our data to test the COARE algorithm, a well-known and widely used diurnal warm layer and skin-temperature model which showed moderate agreement. This dataset will continue to be analyzed and used for model development and validation of diurnal warm-layer prediction and skin temperature modeling.
