An improved Ekman-Birge bottom mud sampler was devised for sampling undisturbed bottom sediment core. The sediment and the overlying water were taken in a transparent plastic cylinder (diameter, 105 mm, height, 300 mm) equipped in the grab box. The grab was driven by an additional weight of 5 kg into sediment. <I>In sitn</I> tests for determining the vertical profiles of chemicals and bacterial populations in the overlying water and sediment proved successful for sampling undisturbed sediment. A large volume of undisturbed sediment for chemical and bacteriological studies was obtained in one trial.
