Other ID: NE-3-79
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Harley J. Knebel
Information Specialist(s): Sally Needell
Data Type(s): Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Sub Bottom Profiler
Scientific Purpose/Goals: Conduct an acoustic survey of the Potomac River to define areas of sediment accumulation, areas of sediment erosion or scour, the thickness of Holocene sediments, the internal structure of the near-surface sediments, the types of bottom topography, and the general geologic history and environmental framework of the estuary.
Start Port/Location: Coltons Point, MD
End Port/Location: Alexandria, VA
Start Date: 1979-05-14
End Date: 1979-05-30
Equipment Used: Air gun, Single channel hydrophone, Sidescan sonar, 2.5 kHz system (batfish), Raytheon radar, Loran-C, Visual navigation
Information to be Derived:
Summary of Activity and Data Gathered: The acoustic study of the Potomac River was quite successful. The boat and equipment functioned quite well and we were able to gather all the data that we set out to get. Sidescan sonar: 481 km; 7 kHz: 481 km; Airgun: 481 km; 2.5 kHz: 246 km.
