Description:

Abstract:

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.

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.

Process_Step:

Process_Description:

Authigenic carbonate samples were collected during HOV and ROV dives. Samples were rinsed with freshwater, allowed to dry, photographed and stored at room temperature.

Process_Date: 2020

Process_Step:

Process_Description:

Authigenic carbonate samples were cut using a diamond band saw to expose fresh surfaces. Subsamples, including discretely drilled powders for isotope and carbon analysis, in order to isolate cement from different precipitation events. Results from the different labs were combined into one spreadsheet. Empty cells are designated by -9999 indicating no analysis was performed.
