Sediment characteristic studies in the surface sediment from Kemaman mangrove forest, Terengganu, Malaysia

Abstract

43 surface sediment samples from Kemaman mangrove forest, Terengganu were analyzed for sediment characteristic (mean, sorting and skewness) off two seasons (dry season and wet season) by using the Particle Size Analyzer (PSA) after digest the sample with Hydrogen Peroxide (H2O2) and Hydrochloric Acid (HCl). There is a significant (P<0.05) relationship between sediment characteristic with the seasonal changes with the increasing mean particle size occurring during the wet season. Finer sediments dominate the mangrove sediment during monsoon season while coarser sediments dominate during the dry season. Meanwhile, sediment mean size for each transect tends to be coarser towards the back mangrove.
