Abstract:

To support the Navys cleanup program, a remotely operated, autonomous instrument, the Benthic Flux Sampling Device, has been developed for in situ measurement of toxicant flux rates from contaminated sediments. A flux out of-or into-the sediment is measured by isolating a volume of water above the sediment, drawing off samples from this volume over time, and analyzing these samples for an increase or decrease in toxicant concentration. This device is used in coastal and inland waters to depths of 50 m. Hazardous waste, Navy cleanup program, toxicity, Chemical contamination, In-place pollutants, Bioremediation.
