Sediment Characteristics of the Andoni Flats, Niger Delta, Nigeria

A baseline study of the intertidal and subtidal zones of the Andoni flats was conducted to determine the basic physical and chemical characteristics of the sediment. Sediment characteristics revealed sandy to loamy (muddy) sand soils with pH of 4.09 to 5.04. Values of organic carbon varied from 0.17% in the sandy soil to 3.01% in the muddy sand soil. Other parameters determined include organic matter which varied between 0.29% and 5.22%, conductivity with values varying from 1120μScm-1 to 1800μScm-1 and water absorbency with values ranging from 21.74% to 43.73%. Particle density, bulk density and porosity of the sediment were also determined for the flats.
