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. Grain-size analyses were used to define the grain-size distribution and sedimentary character of 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.

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: Data quality grades have been assigned to each sample analysis, indicating the accuracy of the grain-size distribution of the sample's coarse fraction. Standards are regularly run for quality control on the Beckman Coulter Multisizer3, ensuring accuracy of grain-size measurements of the fine fractions. Logical_Consistency_Report: Samples' quantified grain-size classification, calculated with workbook macros (see Process Step 3), were compared to the qualitative grain-size classification described by observers on the core's visual description. This was done to ensure that the actual grain-size data was consistent with expected results determined by inspection of physical samples. Completeness_Report: Of the 24 cores collected during the Hugh R. Sharp HRS1209 cruise, 11 cores were analyzed for this grain-size 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. Lineage: Process_Step: Process_Description: Each core was cut into sections on the ship during collection. The cores were then split into halves in the core lab. Subsamples (1- cm thick) were taken from the split cores for grain-size analysis. Process_Date: 2012 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Jason D.

About 50 grams of wet sediment are placed in a pre-weighed beaker, weighed, oven dried at 100°C, and reweighed to correct for salt. The dried sample is wet sieved through a 0.062 mm (No. 230) sieve. The coarse fraction remaining in the sieve is oven dried at 100°C (until completely dried) and weighed. The fine fraction in water is collected in a plastic Nalgene bottle and sealed with a screw lid (stored for no longer than one week). The coarse fraction is dry sieved to determine the individual weights of the 4 to -5 phi fractions, and the weights are recorded in the data entry spreadsheet. At the request of the submitter, shell and shell fragments can be manually removed from the -2 phi and coarser fractions, weighed and their weights are recorded in the data entry spreadsheet. The fine fraction is run and combined using the 200 μm and 30 μm Coulter analyses using the Multisizer3 software (version 3.53) to get the fine fraction grain-size distribution. The fine fraction distribution data are added to the data entry spreadsheet. The spreadsheet is used to calculate a continuous phi class distribution from the original fractions.

Macros in the workbook are run to calculate grain-size classification and statistical analyses. Sample, navigation, and field identifiers, along with continuous phi class distribution data, grain-size classification, and statistical analysis results are copied and pasted into a final Microsoft Excel spreadsheet for each sample submission batch. The processed data are quality control checked and assigned a quality grade based on the examination of the analytical data. Processed data are released to the submitter and incorporated into the laboratory's database. All raw analytical data generated by the samples are archived in the sediment analysis laboratory.

Enumerated_Domain_Value_Definition_Source: Producer defined Attribute: Attribute_Label: Data_Quality_Grade Attribute_Definition: Samples are assigned a quality grade based on the examination of the analytical data. Data quality grades may be determined by several factors, and any comments or notes about the data for a particular sample are included in the results table for that sample under "comments". Quality grades for sample data that do not have any additional comments are assigned based on the calculated percent difference between the weights of the coarse fraction remaining after wet sieving and the sum of all of the weighed fractions after dry sieving the coarse fraction, indicating an estimated differing amount of material which could skew the calculated grain-size results. Letter grades are appended with an identification for the reviewer that assigned the quality grade. In this case, "-BJB" indicates that the quality grade was assigned by Brian J.
