Abstract:
"Conduct the first Lagrangian velocity measurements and numerical simulations of the hydrodynamics of Guanica Bay to support efforts aimed at improving water quality. Project will take place in Guanica Bay and the adjacent waters directly impacted by pollution from the Guanica watershed. The main objective of this project was to understand the physical processes leading to pollutant transport and mixing in Guanica Bay, and this was achieved by conducting the first ever dedicated field observations and hydrodynamic numerical modeling of circulation in Guanica Bay. We built 8 inexpensive GPS-tracked Lagrangian drifters using commercially available hardware and electronics, and several drifter deployments were carried out in and near the Bay under varying physical forcing scenarios. In addition, a 30 day deployment of an acoustic wave and current profiler (AWAC) at the Bay entrance provided long-term observations of the vertical structure of ocean currents in Guanica Bay. These observations as well as the hydrodynamic modeling using the CMS-Flow circulation model have elucidated the dominant mechanisms in the Bay which are responsible for the transport and mixing of the sediment-laden Rio Loco river plume. Finally, several outreach activities including a teacher workshop and five seminars to public schools in Guanica served to communicate the water quality problem of Guanica Bay to its residents and primary users."
