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. The data provides a comprehensive understanding of the nature and properties of the sediments found in this geographic location. Multi-sensor core logger data were used as a non-destructive technique to gather structural properties of the cores. 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.

JPEG Microsoft Windows 10 Enterprise Version 10.0.18363 (Build 18363) Attributes were double checked that they related the correct interval data to the identifiers assigned to the cores. 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. 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. Each core was cut by hand into sections on the ship after collection. These sections ideally were cut into 150 cm lengths, but this may vary depending on overall length of the core, condition of the liner, or other factors 2016 Jason D.
