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...

Results of lipid biomarker concentration and compound specific isotopes analyzed from authigenic carbonates and surrounding sediment collected from Baltimore and Norfolk seep fields along the United States Atlantic Margin are presented in csv format. Samples were collected by the U.S. Geological Survey and Duke University between 2012 and 2015 using remotely operated vehicles (ROVs). Geochemical analysis was performed using gas chromatography (GC) and GC-combustion isotope ratio mass spectrometry (GC-C-IRMS).

Terrain variables extracted from bathymetry were used in combination with stable isotope datasets to construct geospatially-explicit isoscapes that predicted variation in carbon and nitrogen isotopes across the canyon-slope seascape, providing insights into the distribution and flow of energy resources, relevant to understanding whole community function.

First release: 2016 Revised: 2019 Isotopic analyses of authigenic carbonates and methanotrophic deep-sea mussels, Bathymodiolus sp., was performed on samples collected from seep fields in the Baltimore and Norfolk Canyons on the north Atlantic margin. Samples were collected using remotely operated underwater vehicles (ROVs) during three different research cruises in 2012, 2013, and 2015. Analyses were performed by several different laboratories, and the results are presented in spreadsheet format.

Time-series of sediment chemistry, including organic biomarker composition and bulk inorganic geochemical analytes, from samples collected over a one-year period in a sediment trap. The sediment traps were deployed at a depth between 603 m to 1318 m, and they were programmed to rotate a 250 mL sample bottle at 30 d intervals, delivering 12 samples during the 1-year deployment between August 2012 and June 2013. In addition, dissolved water column nutrient concentrations and water column trace element particulate concentrations were collected in Baltimore Canyon on the U.S. Mid-Atlantic Bight (MAB).

The primary objective of this study was to assess deepsea food web structure and trophic niches in Baltimore and Norfolk canyons, the adjacent slopes, and chemosynthetic seeps along the mid-Atlantic margin using stable isotope analyses (SIA) and isotope niche width analysis. We hypothesized that the isotopic compositions of canyon versus slope fauna would be distinct, given differences in the physics and chemistry of the canyons and slopes and resulting quality and quantity of the organic matter available to the benthos. These differences should be evident across taxa and among and within feeding groups. We also used SIA to estimate trophic positions of invertebrates and fishes and to examine changes in trophic...
