Variability in sediment properties with depth and the thickness of individual sedimentary layers are critical determinants of seabed acoustic response. 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.
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. High-resolution magnetic susceptibility (HRMS) measurements were collected to determine the presence and abundance of ferromagnetic and paramagnetic minerals in the cores.
Cores were collected on the 2016 R/V Endeavor cruise EN577 from April 19, 2016 to May 2, 2016. Information about this expedition, also known as USGS Field Activity 2016-001-FA, is available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-001-FA

Drift correction, a measurement of background air to account for any change in sample temperature during the scanning process, was performed every 30 cm down each core.
Magnetic susceptibility data are consistent with expected values according to components and visual observations of sediment cores.
Of the 98 total cores collected during the R/V Endeavor EN577 cruise, 19 piston cores and 9 acoustic/gravity cores were scanned for high-resolution magnetic susceptibility. 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. Data from known gaps in the core (e.g., core section ends), where full coupling between the sensor and the sediment could not be achieved, were removed from the results.
Each core was cut into sections on the ship after collection. The cores were then split into halves back on shore.

Data were collected using Bartington's probe software, Bartsoft for Windows version 4.2.1.2. A Bartington MS3 magnetic susceptibility (MS) meter with a MS2E surface point probe was used to take surface measurements of magnetic susceptibility at 1 cm intervals down sediment cores, starting at a depth of 1 cm. Drift correction measurements were collected every 30 cm to account for temperature change.

Bartsoft software was used to export HRMS data for each core as a tab-delineated text file, which was imported into Microsoft Excel 2008 for data processing. Data from gaps in the core (e.g., core section ends), where full coupling between the sensor and the sediment could not be achieved, were removed from the results. Each core's data were saved as a CSV file.
