Description:

Abstract:

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.

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. Foraminifera biostratigraphy were used to determine microfossil diversity and abundance as well as for atomic mass spectrometry 14C age dating 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. 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

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attributes were checked that they related the correct interval data to sample ID.

Logical_Consistency_Report:

The microfossil populations observed in these samples are generally consistent with expected trends of the marine biostratigraphic record.

Completeness_Report:

Of the 98 cores collected during the R/V Endeavor EN577 cruise, 61 cores were sampled for foraminifera counting.

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 foraminifera counts.

Process_Step:

Process_Description:

Samples in glass vials were picked under a microscope and mounted to a microfossil slide. Slides were photographed with a microscope camera. The numbers of benthic and planktonic specimens were counted, as well as the numbers of different species observed in each sample. Sample weight and species counts were used to calculate populations per gram, as well as the relative abundance of Globobulimina sp. foraminifera.
