Twenty-four piston cores (and associated trigger cores) were collected from the source zone of the Currituck Landslide Complex and upper slope adjacent to Baltimore Canyon by the U.S. Geological Survey and the University of Rhode Island Department of Ocean Engineering during an eight-day cruise aboard the R/V Hugh R. 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...

Porosity, dry bulk density, and average mass accumulation rates, and estimated date of the mid-point of each sediment interval were determined for ten sediment cores retrieved from Lake Lanier in 2018. Physical properties of the sediment (porosity, dry bulk density) were used to help define the pre-reservoir surface and determine the average mass accumulation rate of sediment. This will help to better understand the historical accumulation of sediment and nutrients at select locations in Lake Lanier. The locations were selected to provide supplement a larger study investigating the role of septic systems on Lake Lanier water quality. Sites were distributed among selected study coves (with residential septic systems...

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...
