Title:
Multi-sensor core logger (MSCL) data of sediment cores from the Currituck Landslide Complex and upper slope adjacent to Baltimore Canyon collected on USGS Field Activity 2012-007-FA
Abstract:
Twenty-four piston cores (and associated trigger cores) were collected from the source zone of the Currituck Landslide Complex and upper slope adjacent to Baltimore Canyon by the U.S. Geological Survey and the University of Rhode Island Department of Ocean Engineering during an eight-day cruise aboard the R/V Hugh R. Sharp in September/October of 2012. These cores were analyzed for evidence of seafloor mass transport processes, with an emphasis on constraining the age and shallow stratigraphy of the landslide complex. Sedimentological and geotechnical characterization of the cores was carried out through whole core imaging and description, followed by analysis of discrete samples at the USGS Woods Hole Coastal and Marine Science Center's Sediment Analysis Laboratory and other facilities, including grain-size, CaCO3 content, mineral composition, and bulk index properties (e.g., undrained shear strength and water content), micropaleontologic separations, and geochronology. This data release contains the results of these core descriptions and results of the laboratory analyses.
Supplemental_Information:
Cores were collected on the Hugh R. Sharp cruise HRS1209 from September 28, 2012 to October 4, 2012, and currently reside in the Woods Hole Coastal and Marine Science Center's core repository.

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Attributes were double checked that they related the correct interval data to the identifiers assigned to the cores.
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Of the 24 cores collected during the Hugh R. Sharp HRS1209 cruise, 22 cores were analyzed using the multi-sensor core logger. Cores 4 and 24 were omitted cores because the coring locations were near previously analyzed cores.
  5. How consistent are the relationships among the observations, including topology?
    Results of P-wave amplitude and velocity, density, and magnetic susceptibility analyses are generally consistent with expected values. Data for cores HRS1209-1PC and HRS1209-6PC do not include the attribute Modified Depth. Those data were not included in the dataset.
