Distributions of organic carbon (OC) and total phosphorus (P) in the sediments of three mangrove ecosystems located at Veli, Kochi and Kannur areas, southwest coast of India are described. The mangrove sediments of Kannur contain comparatively high concentration of DC (4%) than that of Veli (2.6%) and Kochi (3.7%). Total P records the highest concentrations in Kochi (av. 0.395%) compared to Veli (0.055%) and Kannur (av. 0.323%) mangroves. However, their distribution does not yield any specific pattern with respect to landward, intermediate and shallow water profiles. Statistical analysis of OC and P contents against the various causative factors stresses the role of particle size in regulating their distributional pattern in mangrove environments.

Abstract


Distributions of organic carbon (OC) and total phosphorus (P) in the sediments of three mangrove ecosystems located at Veli, Kochi and Kannur areas, southwest coast of India are described. The mangrove sediments of Kannur contain comparatively high concentration of DC (4%) than that of Veli (2.6%) and Kochi (3.7%). Total P records the highest concentrations in Kochi (av. 0.395%) compared to Veli (0.055%) and Kannur (av. 0.323%) mangroves. However, their distribution does not yield any specific pattern with respect to landward, intermediate and shallow water profiles. Statistical analysis of OC and P contents against the various causative factors stresses the role of particle size in regulating their distributional pattern in mangrove environments.
