Other ID: AII 122
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Michael Bothner
Affiliate Investigator(s): J. Fred Grassle, Rutgers University
Data Type(s): Location-Elevation: Navigation, Sampling: Geology, Sonar: Multibeam, Time Series: Mooring (physical oceanography), Visual Identification: Submersible Observations
Scientific Purpose/Goals: To test the hypothesis that particles from municipal sewage sludge disposal at Deep Water Dump Site 106 can be detected on the deep-sea floor in the vicinity of this dump site (2250-2750 m water depth). USGS objectives were to construct a detailed bathymetric map using SeaBeam (URI), deploy instruments to monitor currents and sediment transport, and collect samples to evaluate rates of sediment mixing and accumulation and levels of chemical contaminants in surficial sediments.
Start Date: 1989-09-15
Start Port/Location: Woods Hole, MA
End Date: 1989-09-26
End Port/Location: Woods Hole, MA
Equipment Used: SeaBeam 2112, Loran-C, Push corer (wh), Bottom tripod, Submersible Observation
Information to be Derived: Time series data; Samples and chemical analysis; Grain size analysis; Suspended sediment concentrations; Sea floor map; Bathymetric maps;
Summary of Activity and Data Gathered: Data acquired include a Sea Beam bathymetric map and digitally recorded depth data from a survey area of about 520 nmi2 (or about 1750 km2), sediment samples from gravity cores and Alvin-manipulated corers (some cores were subsampled at sea), and the usual video, camera and audio descriptive data generated by ALVIN. Current-meter and sediment-trap data retrieval tentatively scheduled for OCEANUS cruise in May 1990. Moorings deployed: 2 (#336 and 337 recovered FA 90026 OCEANUS 222 Aug. 2-7, 1990).
