This document describes the work of a group focused on submarine topography and geomorphology. The group conducts bathymetric surveying and mapping of the seafloor. It has carried out numerous mapping projects of the China seas totaling over 4.5 million km of seafloor surveyed. The group's work involves fields like geology, geomorphology and hydrology. It has produced academic papers, books, and atlases on submarine topography and geomorphology of the China seas.
