Abstract

The mangrove ecosystems are highly productive intertidal forests distributed along the tropical coast and they stabilize the coastal zone from erosion and act as a buffer zone between land and sea.A study was carried out to investigate the distribution and monthly variation of textural characteristics and organic matter in surface sediments around the mangrove forests of the Manakudy estuary, which is in the southwest coast of India. Organic matter varied from 2.4% to 11.9%. Organic matter was high in Station 7 in all months because it was inside the mangrove forest. Calcium carbonate varied from 4.2-18%. It was high in station1 and station6. Sulphur was significantly negative correlation with organic carbon at 0.05 level. Manakudy mangrove sediments, sand is the major fraction and it is coarsely skewed and planty to extremly leptokurtic in nature.
