Abstract

Seasonal Distribution of Organic Carbon in the Surface Sediments of the Terengganu Nearshore Coastal Area

Highlights

  • Terengganu water experienced the semi annual reversal in the wind system and the reversal in the current flow, in the upper layer of the ocean

  • High organic carbon concentrations could be primarily caused by the river run-off, which seem to have been the main supply of organic matter into the coastal area

  • Low organic carbon concentration in the study area may be due to the sediment grain size which was dominated by moderately coarse sand

Summary

Introduction

Terengganu water experienced the semi annual reversal in the wind system and the reversal in the current flow, in the upper layer of the ocean Due to this reason, a north east monsoon season and a south east monsoon season, can be clearly distinguished in the South China Sea. Due to this reason, a north east monsoon season and a south east monsoon season, can be clearly distinguished in the South China Sea Their coastal near shore areas are active sites where huge amount of organic matter is introduced into the ocean system through river runoff, in situ primary production and anthropogenic impacts. Different factors may control the partitioning and the bioavailability of the hydrophobic organic compound pollutants within the benthic ecosystem. Through the processes of sediment resuspension and redistribution, organic matter at the sediment-water interface may be a significant source of remineralizable materials
