Sediment, Chlorophyll ‘a’, Nutrients, Bonny estuary, Amadi-Ama Creek, Port harcourtAbstract
The sediment chlorophyll ‘a’ and nutrient characteristics of the Amadi-Ama creek was studied for 24 months between January 2009 – December 2010.Sediments samples collected from the water bed at low tide were analysed for the variable following standard methods. The data were subjected to analysis of variance(ANOVA), Duncan Multiple range test(DMR) and pearson correlation coefficient.They all showed spatial and seasonal variations with higher values in the dry season than the wet season except Chlorophyll ‘a’, and sulphate which did not show seasonal difference for the two years. The highest values of chlorophyll ‘a’ and sulphate were observed in station 3 throughout the period of study.
