| Purpose | Seafloor characterization of seeps, canyons and reefs | ||||||||
| Location | South Atlantic Bight; offshore NC, GA and FL | ||||||||
| Summary | Covered 4,167 kilometers over 22 days at sea in depths of 135-3,175 meters. Collected 1,821 linear kilometers (6,733 square kilometers) of EM122 multibeam bathymetry and backscatter. Collected 89 files of EM122 water column data over 6 days.Collected 1,270 kms of seismic profile data. 11 ROV JASON (WHOI) Dives, 18 CTDs and deployed 2 Landers. Each ROV dive has video, photos, and numerous physical and bilogical samples. Physical samples are being processed by USGS Woods Hole Sediment Lab and will be logged here once when processing is complete. | ||||||||
| Info derived | Grain size, carbonate content, sediment age, rock types | ||||||||

| Results from isotope analysis of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic | ROV | Geochemical analysis of carbonate rock samples collected from seep fields on the RB1903 and AT41 research expeditions in the U.S. Mid- and South Atlantic. Samples were collected as a fingerprint to past hydrocarbon seep activity, fluid source, and depositional environment. | Nancy G Prouty |
| Geochemical and mineralogic analysis of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic | ROV | Geochemical and mineralogic analysis of selected carbonate rock samples collected from seep fields on the RB1903 and AT41 research expeditions in the U.S. Mid- and South Atlantic. Samples were collected as a fingerprint to past hydrocarbon seep activity, fluid source, and depositional environment. Analyses include: Wavelength-dispersive X-ray Fluorescence (WDXRF) major element, Inductively Coupled Optical Emission Spectroscopy/Mass Spectroscopy (ICPOES-MS) major and minor element, and x-ray diffractrometry (XRD) mineralogy. All WDXRF and ICPOES-MS samples were analyzed by the U.S. Geological Survey Minerals Resource Program Analytical Geochemistry facility via its contract laboratory, AGAT Laboratories.XRD samples were analyzed at the Woods Hole Coastal and Marine Science Center. | Jason Chaytor |
| Accelerator Mass Spectrometry (AMS) 14C radiocarbon analysis of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic | ROV | Results are presented from Accelerator Mass Spectrometry (AMS) carbon-14 radiocarbon dating of carbonate rock samples collected from seep fields offshore the U.S. Mid- and South Atlantic in 2018 and 2019. Samples were collected as a fingerprint to past hydrocarbon seep activity, fluid source, and depositional environment. | Jason Chaytor |
