Xia Shaohong research team of Guangzhou Marine Laboratory carried out the research on P-wave velocity structure by using the active source OBS wide-angle seismic data, which provided important information for in-depth understanding of magmatism and crustal extension in the continental margin of the northern South China Sea. Relevant research results were recently published in Tectonophysics.

On April 14, Guangdong Provincial Laboratory of southern marine science and Engineering (Guangzhou) organized and held the expert demonstration meeting of scientific research projects in 2019 in Guangzhou.
