Data Analysis and Synthese for the ONR undersea Sand Dunes in the South China Sea field experiments

Abstract

Abstract Two field programs to study shoaling nonlinear internal waves and their interaction with a newly-discovered submarine sand dune field have been successfully executed in the northeastern South China Sea. The pilot study during spring 2013 used ship-based operations to a) further delineate the dune field and determine its mobility; b) begin characterizing the nonlinear internal wave climate at the site; and c) conduct preliminary investigations of the acoustic transmission loss along and across the dune field. During the main field program in June 2014, ten oceanographic/acoustic moorings spanning the dune field in both directions were deployed, and longer and more comprehensive shipboard surveys were conducted. This proposal is to analyze and published the results from these experiments. The program is anticipated to add fresh insights to internal wave transformation under shoaling over rough topography, as well as acoustic propagation loss along and across the dune crests.
