Start Date



In previous research projects, Nova Southeastern University (NSU) has developed and implemented the Nova Environmental Sensor Suite (NESS) including acoustic Doppler current profiler (ADCP), conductivity temperature depth (CTD), and bottom pressure moorings. In parallel, NSU has developed a prototype high-resolution oceanographic and magnetohydrodynamic model for Navy applications. Most recent developments include the implementation of Teledyne Slocum gliders and a Wirewalker in a strong current and testing a Wave Radar. The long-term goal of these Navy-NSU joint activities is to support the development of a model including data assimilation that will be useful for cancelling the electromagnetic noises produced by natural oceanic processes in the US Navy surveillance systems. The computational fluid dynamics model (CFDM 1 and 2) has been developed within the previous NSU contract with Navy. Testing of this model with the field data in the energetic ocean circulation in the Straits of Florida has provided encouraging results for predicting ocean currents with high resolution in the areas of Navy interests around the world. In this new project, our specific tasks are as follows: Conduct a feasibility study of different data assimilation systems in application to the Ansys CFD and the NESS data. Develop a plan to assimilate South Florida and regional oceanographic data into CFD-MHD model with assistance from a consultant at NRL and an ultimate goal of increasing fidelity and improving model predictions. Evaluate options for DTS implementation and assess modeling benefits. Research existing Navy technology available and how it may be best implemented on the SFOMF range and suitability for the CFD-MHD model. Permanently install WaMoS® X-Band wave radar purchased under previous contract. Plan a three-month experiment, including running the CFD-MHD model, for an overseas alternate location in the UK with the portable NESS. Upgrade and harden existing Wirewalker mooring for future use in the Pacific. The NESS including the ADCP, CTD, bottom pressure, and bottom magnetometer moorings will serve as a stand-alone system for obtaining environmental data around the world. When tested and verified, the upgraded CFD-MHD and NESS can serve as a tool for predicting the ocean circulation and the magnetic signature of sub-mesoscale oceanographic processes including internal wave solitons at any location in the World Ocean.
