Description:

Abstract:

Results of radiocarbon dating of deep-sea (500 m to 700 m) black corals are presented. These corals were collected off the southeastern United States as part of the Southeastern United States Deep-Sea Corals (SEADESC) Initiative.

Purpose:

These samples were collected as part of on-going research on the outer continental shelf in collaboration with the National Oceanic and Atmospheric Administration (NOAA) and Bureau of Ocean Energy Management (BOEM) to characterize hard-bottom communities, including deep-sea corals and chemosynthetic habitats, as the need for oil and gas exploration, and wind energy increases on the U.S. Atlantic shelf and slope. Information on life spans of deep-sea corals is essential for conservation and management and for assessing the vulnerability of these organisms to both natural and anthropogenic perturbations.

Supplemental_Information:

Samples were collected during two Harbor Branch Oceanographic Institute research cruises and therefore no USGS field activity information exists.
Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
