Cruise Report: South China Sea Upper Slope Sand Dunes Project, May 8-14, 2013

Abstract

Under ONR sponsorship and in partnership with Taiwan, a field project to investigate the effects of the large amplitude sand dunes, discovered on the upper slope of the northeastern South China Sea, on acoustic signal propagation and reverberation was launched. The research is interdisciplinary in nature, coordinated and carried out jointly by ocean acousticians, physical oceanographers and marine geologists. The experimental phase of the project entails a multibeam survey of the experimental area in 2012, a pilot experiment in 2013, and the main experiment in 2014. The pilot experiment was carried out during May 8-14 using two Taiwanese research vessels, R/V OCEAN RESEARCHER 5 (OR5) and R/V OCEAN RESEARCHER 2 (OR2). The pilot experiment successfully collected the needed initial data (acoustic transmissions, ambient noise and environmental data), tested a pop up recovery mooring design, and examined the capability of the new OCEAN RESEARCHER 5 to carry out the work. The data and information collected are critical to the scientific and technical design as well as logistical planning for the main experiment. This cruise report documents the operations during the pilot experiment and the data collected with quick-look scientific results.
