The New England Mud Patch (NEMP), located south of Cape Cod, is an unusual feature on the U.S. Continental Shelf in that it is composed of fine-grained sediment layers containing a relatively-homogeneous mix of sand, silt, and clay-sized particles bounded by more typical sandy shelf sediments. The unique characteristics and nature of this deposit is due to a derivation of sediments that have been transported to, and deposited in, a basal bowl-shaped depression since the last glacial maximum. Ninety-two piston, vibra-, and gravity cores with a maximum length of 8.2 meters were collected from across the New England Mud Patch during a 2-leg, 10-day cruise aboard the R/V Endeavor in the spring of 2016. Geologic characterization and analysis of a subset of the cores including grain size, CaCO3, mineral composition, and bulk index properties (undrained shear strength, water content, density, and porosity) of discrete samples was carried out at the USGS Woods Hole Coastal and Marine Science Center's (WHCMSC) Sediment Analysis Laboratory. This data release contains the results of these analyses, along with visual core descriptions and summary sheets for each core analyzed for this study. Purpose: The data gained through the analyses of cores collected from the New England Mud Patch help provide a comprehensive understanding of the nature and properties of the sediments found in this geographic location. Bulk organics 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 2016 R/V Endeavor cruise EN577 from April 19, 2016 to May 2, 2016.

Logical_Consistency_Report: Data fall within generally expected ranges. Completeness_Report: Of the 98 cores collected during the R/V Endeavor EN577 cruise, 66 cores were analyzed for this loss-on-ignition dataset. Cores chosen for analysis were those that were thought to represent the full range of sediments expected to be encountered. Any cores omitted from analysis were not included because the coring locations were in close proximity to previously analyzed cores. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: For piston and trigger cores, the horizontal location accuracy is less than 1 meter. For vibracores and acoustic cores, location accuracy is approximately 3 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Water depth accuracy is within 1 meter.

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 intervals and placed into pre-weighed aluminum dishes. Other samples in this dataset include dry bulk density ("DEN") and water content ("WC") samples that were analyzed for CC-LOI after geotechnical analyses were complete. Dry 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 ceramic crucible. Process_Date: 2019 Process_Step: Process_Description: Filled crucibles were heated in a muffle furnace for Loss on Ignition 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.
