Results from isotope analysis of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic Human Operated Vehicle (HOV) Alvin (AT41) 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 Human Operated Vehicle (HOV) Alvin (AT41) 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.

Accelerator Mass Spectrometry (AMS) 14C radiocarbon analysis of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic Human Operated Vehicle (HOV) Alvin (AT41) 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
