HUBUNGAN SEDIMEN DASAR PERAIRAN DENGAN PENYEBARAN LAMUN (Seagrass) DI TELUK PARE PARE, SULAWESI SELATAN
ABSTRACT: Sedimentological and
Oceanographic study has been carried out in coastal waters of the Pare-Pare
Bay, South Sulawesi in March 2008. The objective of the study was to
investigate the relationship between bottom sediments (substrate) and seagrass
distribution. Eight (8) stations along coast of Pare-Pare Bay were chosen for
measurements of bottom sediment grain size, water temperature, salinity,
turbidity, water depth, current speed, and wave height, seagrass species
composition and density. Sediment samples were analyzed using dry sieving
method and classified based on grain size according to Wentworth scale.
Seagrass data was collected using quadrate transect. Correspondence analysis
was used to determine the relationship between sediment and seagrass
distribution. Correspondence analysis revealed that Thalassia hempricii,
Cymodocea rotundata, and Cymodocea serrulatawere dominant in thevery coarsesand
substrate (particle size 1- 2mm). Fine sand (0,125 – 0,250 mm) substrates were
dominated by Enhalus acoroides, Halophila minorandSyringodium isoetifolium.
Substrate with coarse sand was found to be suitable for Halophila ovalis. The
results of this study indicating that distribution of seagrass was closely
related with the bottom sediment type (substrate) in the study site.
