Sebaran Fraksi Sedimen Dasar Permukaan di Perairan Pantai Pulau Topang Provinsi Riau

Abstract

Abstract:

A study was conducted in december 2013 in coastal waters Topang Island Riau
Province, with a view to learn the environmental conditions under the deposition of
oceanography and physics. The method used is a method of surveys carried out at 12 stations
without repetition and 2 times repetition on calculations of the quality of the waters .The
results of research shows that bottom sediment surface waters can be grouped into three
faction sediment is sandy mud , muddy sand and sand .Sand faction dominating at any
research station with type 2 is sand and muddy sand .Based on the parameter of sediment as
the diameter of average (Mz), sorting ( ), skewness (Sk1) and kurtosis (KG), physical
oceanographic conditions in Western and Eastern parts of the island tend to be stable
compared to the North and South. Current speed of surface affect the distribution of the
bottom sediment surface.
Key words: bottom sediment surface., Coastal waters, Topang
