Samples were collected as a fingerprint to past hydrocarbon seep activity, fluid source, and depositional environment. Purpose: 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.
