Dataset description: Accelerator Mass Spectrometry (AMS) 14C radiocarbon analysis of authigenic carbonates collected offshore the U.S. Mid- and South Atlantic

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.

2018-042-FAHuman Operated Vehicle (HOV) Alvin Sampler
HOV Alvin enables in-person observation and sampling in deep-sea environments, which is critical for: studying hydrothermal vents, cold seeps, and coral habitats; collecting biological, geological, and chemical samples; and deploying instruments and conducting video surveys. Operating Depth: 6,500 m (21,325 ft); Sampling Tools: Two Schilling Titan manipulators, sample basket, water samplers, tube corers, bio boxes; Science Payload: ~181 kg (400 lbs).
