This report provides new data acquired by monitoring of hopper dredging operations at the York Spit Channel in southern Chesapeake Bay. Turbidity was measured and acoustical sensing was performed from a vessel tracking through the plumes while water samples were obtained at fixed stations for analyses of salinity and total suspended sediment concentrations. Other parameters include temperature and thickness of deposited layers. The plumes were monitored June 14, 1988 for 8.5 hours and six dredging cycles along the channel length. Most of the dredged material is silty sand. Normal background concentrations before dredging are in the range 2.6 to 17 mg/1.
