Physical Characteristic of Bathymetry in the Inner Gulf of Thailand
Abstract
This research aims to construct physical bathymetry of the inner Gulf of Thailand using the digitized depth data from 18 Navigation charts of the Hydrographic Department, the Royal Thai Navy as well as the high-resolution bathymetric data analysis. As a result from cross-sections, the seafloor of the inner Gulf of Thailand shows a general smooth area from the river mouths to the central of the Gulf with slightly slopping southward. The bathymetry in northern and western parts of Gulf displays more flat area than those appears in the southern and the eastern parts. Bathymetric depth of the inner Gulf varies from 0-50 m from the mean sea level. Slope of the seafloor around the river mouths and coastal zone is very low. The area in the east is clearly deeper than the west while the central area is generally smooth. The seafloor in the east is characterized by mounds topography and shallow basin. The area around the Islands is partially dominated by submarine channels.
