The Benthic Flux Sampling Device (BFSD) is a benthic lander for in-situ measurements of metal contaminant fluxes from or into shallow marine sediments. The BFSD collects seawater samples at timed intervals from an open-bottomed chamber of known volume which encloses a known surface area of sediment. The seawater in the chamber is continuously mixed and monitored for key water quality parameters.
The BFSD was designed to characterize metal contamination problems in bays, harbors and coastal waters resulting from a variety of sources, including ships, shoreside facilities, municipal outfalls, spills and non-point source runoff. The technology provides a means to assess contaminant mobility by directly measuring and quantifying the contaminant flux across the sediment-water interface.
