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. Bulk organic matter and carbonate content analyses were used to determine the percentage of organically-derived material present in samples collected from the cores. 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.

Sharp HRS1209 cruise, 11 cores were analyzed for this loss-on-ignition dataset. Cores chosen for analysis were thought to represent the full range of sediments expected to be encountered. Omitted cores were not included because the coring locations were near previously analyzed cores.

Process_Step: Process_Description: Carbon content loss-on-ignition (CC-LOI) samples data with Sample_ID containing "CC") were taken from cores in 1 cm-thick subsamples and placed into pre-weighed aluminum dishes. Samples were weighed after drying in oven at 100 degrees Celsius for at least 24 hours. The dry sample was powdered using a mortar and pestle. 2-4 grams of dry powder were transferred to a pre-weighed ceramic crucible. Process_Date: 2019 Process_Step: Process_Description: Filled crucibles were heated in a muffle furnace for CC-LOI in two stages, using a modified method outlined by Dean (1974). Crucibles were heated to 550 degrees Celsius for 3 hours, cooled, and weighed. Weight differential after the first heating step is assigned to loss of organic matter. Samples were then heated at 950 degrees Celsius for 2 hours. The second weight differential is equated to loss of carbon dioxide from CaCO3 in the sediment.
