Other ID: AN-1-77
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: Middle Atlantic Outer Continental Shelf, Baltimore Canyon Trough area, New Jersey, Delaware, Maryland, United States, North America, North Atlantic;
Principal Investigator(s): Harley J. Knebel
Affiliate Investigator(s): Jim Katsolis - Ocean/Seismic/Survey, Inc., Norwood, NJ
Data Type(s): Location-Elevation: Navigation, Sampling: Geology, Seismics: Sparker
Scientific Purpose/Goals: Obtain a set of vibracores at selected locations across the continental shelf. Core stations were selected so as to maximize the chances of sampling the muddy horizon beneath the surficial sand sheet. Geotechnical measurements (including grain size, liquid/plastic (Atterberg) limits, moisture content, and consolidation/compression tests) subsequently will be made on samples from the muddy stratum. A set of cores was also taken to provide the necessary sediments for age dating. Finally, additional seismic records (Minisparker) were collected.
Start Date: 1977-09-18
Start Port/Location: Woods Hole, MA
End Date: 1977-09-25
End Port/Location: Woods Hole, MA
Equipment Used: Sparker system, Alpine Vibracorer, Loran-C, Single channel hydrophone
Information to be Derived: Sea floor map; Morphology;
Summary of Activity and Data Gathered: Because of poor weather, heavy seas, and long travel time to and from the survey area, coring time was limited to 2 full days and 2 half days. Therefore core locations were clustered in the northern part of the survey area. We obtained a set of cores from a transect across the shelf just south of Hudson Channel along a potential pipeline corridor leading to New York and New Jersey. We also obtained many cores in and around the northern subarea recently leased for oil exploration. Most of the cores penetrated the muddy horizon beneath the surficial sand sheet. Replicate cores were obtained at 3 stations. Minisparker lines: 377 km; Vibracores: 20.
