Prouty, N.G., and Chaytor, J.D., 2022, Carbonate chemistry measurements of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic in 2018 and 2019 as part of the DEEPSEARCH Project: U.S. Geological Survey data release,


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 [...]

These samples were collected as part of the Deep Sea Exploration to Advance Research on Coral/Canyon/Cold seep Habitats (DEEP SEARCH) study, a multiyear, multi-agency campaign to characterize the deep-sea ecosystems to better understand the distribution of sensitive seafloor communities to inform potential offshore energy development and other deep-sea management.
