Spatial and seasonal variability in sediment parameters of Amadi-Ama Ckeek, port Harcourt, Nigeria

The spatial and seasonal variability in sediment parameters of Amadi-Ama creek were investigated for 2years (January2009 and December 2010). Sediment samples collected were analyzedfollowing the standard limnological methods of APHA and values subjected to statistical analysis(p<0.05).The study revealed that onlytemperature did not exhibit spatial significant difference while other parameters such as pH, conductivity, nitrate, sulphate, phosphate and chlorophyll ‘a’ all differed significantly in both years. By the exception of nitrate and phosphate, all other parameters/nutrientsexhibited significant difference seasonally. The parameters and nutrients such as pH, sulphate and chlorophyll ‘a’ recorded highervalues in the dry season than the wet season while conductivity was higher in the wet season than the dry season. Temperature, nitrate and phosphate values fluctuate during the period of study. The recorded chlorophyll ‘a’ values placed Amadi-Ama creek between mesotrophic and euthrophic status
