| Description |
Organic matter was analysed on the silt-clay fraction of forty eight sediment samples from the continental shelf off Kochi, west coast of India. It was found to be high in the recent, near shore silt-clay predominant sediments towards Alleppey (average 3.8%) than those towards Azhikode (average 1.97%). The sand predominant offshore relict sediments contain very low organic matter values (average 0.71%). The high organic matter content in the inner shelf is mainly controlled by the fine texture of the sediment in conjunction with other parameters like primary production in the overlying waters, terrestrial organic detrital supply and alongshore currents indicating present day deposition. The low amount of organic matter in the outer shelf may be due to existing high energy non-depositional conditions for the settlement of fine sediment, high dissolved oxygen in the overlying waters and sandy texture of the sediment representing mid-Holocene deposition
