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...
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...

The Aquatic Core Networks, Unstratified is comprised of unstratified versions of Lotic Core Areas and Lentic Core Areas. These datasets are one of two versions of aquatic core areas that are part of a suite of products from Nature’s Network (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. Although the stratified version “Aquatic Core Networks” is considered by the planning team to be the primary version for users, this unstratified version is also made available for reference and use.These and other datasets that augment or complement the Aquatic...

The aquatic core networks is one of a suite of products from the Nature’s Network project (naturesnetwork.org). These datasets represent the aquatic core networks, which include lotic and lentic core areas and aquatic buffers. NOTE - The aquatic buffers dataset has been converted to integers and only contain values of 90 -100 (0.9 - 1) for online purposes, the original dataset is included in the download and contains all values. All datasets in this map are included in the download. The aquatic core networks represents intact, well-connected stream reaches, lakes, and ponds in the Northeast and Mid-Atlantic region that, if protected as part of stream networks and watersheds, will continue to support a broad...

The set of terrestrial ecosystem core areas (unstratified) is one of two versions of terrestrial and wetland core areas that are part of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. While the other version of terrestrial cores (Terrestrial Core-Connector Network, Northeast U.S.) is considered by the planning team to be the primary version for users, this version is also made available for reference and use. A number of additional datasets are also available in the Nature’s Network gallery:...
