The Catalogue of Core Logging Sheets for Sediments of the Western Gulf of Thailand and Eastern Peninsular Malaysia in April 1996

Oceanographic survey on bottom sediment characteristics has been conducted in the sea areas in the western part of the Gulf of Thailand and the Eastern Peninsular Malaysia as one research program under the collaborative research project between SEAFDEC’s Training Department (TD) in Thailand and the Marine Fishery Resources Development and Management Department (MFRDMD) in Malaysia. This research program was carried out because of the interest in the nature of sea bottom in an area of which only few detail information exist. The information such as vertical distribution of different types of sediments, relationships among sediment physico-chemical process, biological processes in the water column and other fishery resources were of primary interest. The sediment samples surveyed in the Western Gulf of Thailand and Eastern Peninsular Malaysia during April 1996 were immediately recorded for their visible characteristics on board of M.V. SEAFDEC in core logging sheets by using general lithological symbols. The catalogue of core logging sheets here could thus be applicable to easily distinguish the vertical profiles of those bottom sediments. Such visible characteristics could also simply reflect both physic-chemical and biological compositions of bottom deposits in the designated areas
