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. Water content and grain density analyses were used to determine the density and porosity of 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: Results of water content and density analyses are generally consistent with expected values. Completeness_Report: Of the 98 cores collected during the R/V Endeavor EN577 cruise, 74 cores are included in this set of water content and density data. 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.

Water content samples were collected from sediment cores using a spatula, then placed into a pre-weighed aluminum tray or glass beaker. Sample was then dried at 100 degrees C after at least 24 hours, then reweighed. Pre-dried sediment samples, some previously analyzed for bulk density, were further analyzed for density using a HyPyc gas pycnometer.

In total, 796 water content and MAD analyses were performed; 123 samples were analyzed with a pycnometer.
