Formation of Dunes on the Upper Slope by Internal Solitary Wave in the South China Sea

Abstract

Reeder et al (2011} discovered large sand dunes, with lengths of approximately 300 m and heights up to16 m, on the upper slope in the South China Sea (Figure 1), the site of the world's largest observed internal solitary waves (ISW; Ramp et al. 2006, Chao et al. 2007, Shaw et al. 2009; Figure 2). The dunes, unique in their slope location and possible formation by ISW, are of interest intrinsically and because similar seafloor features in other locations are known to refract and focus low-frequency sound (Ballardet al 2012). The processes that form the dunes and determine their occurrence and scales have not been determined.
