A wide-angle refraction and coincidental single-channel reflection seismic survey (line OBS2019–1) was acquired across the northeastern continental margin of the South China Sea (SCS). S-wave velocity and Vp/Vs ratios are obtained based on a previously published P-wave velocity model. The upper and...
