Abstract

The Physical Oceanography Laboratory at Nova Southeastern University’s Halmos College of Natural Sciences and Oceanography (NSU HCNSO) Laboratory conducted observational, computational, and theoretical studies from 2015 through 2020 in support of the South Florida Ocean Measurement Facility (SFOMF). These studies characterized the physical oceanographic environment, including velocity profiles, pressure, conductivity, temperature, density, electromagnetics, and surface wave fields. The theoretical and computational work included the development of a transient 3D computational fluid dynamics (CFD) model coupled with magnetohydrodynamics (MHD) that requires ocean current and conductivity data inputs in order to predict induced electric and magnetic fields signal over space and time from internal waves. This model is ongoing development to reflect the realistic bottom topography applicable for the Port Everglades Vicinity. During this new project, we will design an experiment to identify and study the dynamic processes that govern motion of water, understand the variability of the resulting internal wave fields, and to improve the existing CFD-MHD model developed at NSUOC. A detailed resolution of the sea floor boundary layer velocity profile will be measured using downward-looking high-resolution short-range current profilers. The upgraded mooring system will also include new high-performance magnetic sensors in addition to the equipment procured in the previous experiments. Field data may be supplemented with gliders and SAR information as useful and available. NSUOC will analyze and reduce all data collected under auspices of NSWCCD. The project will include liaisons for coordination between NSU and the Navy. Collaborations may include NRL and ONR researchers as well as other U.S. universities and private organizations as required. This project will train a new generation of specialists in the field of naval research. This research will be of interest to Naval programs on a long-term basis and for different locations in the World Ocean due to the portable design of the mooring system. The project will extend the experimental, computational, and theoretical knowledge base obtained locally to other areas of interest.
