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. Purpose: The data provides a comprehensive understanding of the nature and properties of the sediments found in this geographic location. Visual descriptions of the cores were used as a reference for determining sampling intervals and estimating the depths of major lithologic changes. 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.

Browse_Graphic_File_Type: JPEG Native_Data_Set_Environment: Microsoft Windows 10 Enterprise Version 10.0.18363 (Build 18363) Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Visual descriptions, particularly surface color and sediment texture, are largely qualitative and subject to the observer's interpretations. Logical_Consistency_Report: Visual description data are qualitative and subjective; this dataset does not contain analytical results. Completeness_Report: Of the 24 cores collected during the Hugh R. Sharp HRS1209 cruise, 13 cores (cores 1-14, excluding core 4) were visually described and documented. Cores chosen for analysis were thought to represent the full range of sediments expected to be encountered. Lineage: Process_Step: Process_Description: Sediment cores were cut into sections on the research vessel and later split in half in the laboratory. Process_Date: 2012 Process_Step: Process_Description: Each core was described in the laboratory. The features observed include color (based on the Munsell color chart), overall texture, and presence of shells and other biogenic material. Distinct and indistinct unit boundaries were identified with sedimentological changes. A torque meter was used to measure the vane shear strength of the material, recorded every 10 cm of depth in fine-grained sediment. Shear strength was not measured in sediment coarser than silt.

Sharp during the 2012 HRS1209 cruise. After collection and splitting, the sediment cores were observed for visual changes grain-size texture, color, lithology, and sedimentary structures. Visual description sheets also contain location information, identifiable macrofossils and shell fragments, and torque gauge measurements for calculating shear strength. The dataset is composed of one PDF file. A list of core IDs and sampling locations for this field activity are listed in "Collection locations of sediment cores from the Currituck Landslide and Baltimore Canyon collected on USGS Field Activity 2012-007-FA" within the greater work.
