Description The sediment trap design used here successfully collected undisturbed samples of suspended particulate matter (SPM) in sufficient quantity to allow analysis of a variety of physical and chemical parameters. This suggests that the trap design would also perform well when deployed in similar environments: nearshore marine areas with current velocities approximately in the range of 2-28 cm/sec. In addition, under the conditions present in City Waterway, the chemical and physical data presented suggest that the amount of resuspended material collected by the traps is probably low. However, additional data will be required to quantify the amount of resuspension.
