4-D Current Experiment Using AUV and HF-Radar
Abstract
The goal of the proposed study is to understand the role of small-scale physical processes in the coastal ocean through observations of the four-dimensional current variability. The approach combines the Florida Atlantic University Autonomous Underwater Vehicle (AUV) technology with the RSMAS Ocean Surface Current Radar (OSCR). The engineering part of the proposed research seeks to develop, integrate and test instrumentation designed to measure and characterize the subsurface current structure from AUVs. The working scientific hypothesis is that subsurface and surface currents are dynamically linked through the internal wave continuum such that the four-dimensional physical environment can be reconstructed by integrating AUV, OSCR, shipboard and moored observations. In terms of fluid dynamics, the scientific part of this investigation relates observed current patterns induced by winds (Ekman), low-frequency flows and tides to internal waves in a regime with variable stratification and bottom topography.
