Using bomb-14C dating and growth ring counting methods, we calculate life spans and growth rates of six species of deep-sea corals collected at depths of between 400 and 900 m from the continental slope of Newfoundland and Labrador. Bamboo corals ( Acanella arbuscula , Keratoisis ornata ) and antipatharians ( Stauropathes arctica ) secrete concentric growth rings in their axial skeletons, which were proven to form annually for K. ornata and S. arctica. These species had the lowest radial growth rates of 33 ± 11 to 75 ± 11 μm·year–1. Primnoa resedaeformis and Paramuricea spp. had higher radial growth rates of 83 ± 6 to 215 ± 37 μm·year–1. Paragorgia arborea had the highest radial growth rate of 830 ± 120 μm·year–1. Axial growth rates ranged from 0.56 ± 0.05 cm·year–1 for a specimen of Paramuricea spp. to 2.61 ± 0.45 cm·year–1 for a specimen of Primnoa resedaeformis . Life spans ranged from 18 ± 4 years for a live-collected P. resedaeformis to 200 ± 30 years for a subfossil specimen of K. ornata. Because all of the corals were from heavily fished areas, it is likely that age distributions are biased towards smaller and younger colonies. Recovery of deep-sea corals from fishing-induced damage will take decades to centuries.

The oceans make up about 70% of the earth’s surface and serve as habitats for many deep and shallow creatures. In depths of about 50 meters and more, deep-sea corals and sponges occur mostly along seamounts, continental margins, undersea canyons and ridges. They, deep-sea corals and sponges, play a key role in supporting the health of the ocean as they preserve the biodiversity and long-term sustainability of commercial and recreational fish species. With the many benefits that are attached to deep-sea corals and sponges, the Deep-Sea Corals and Research Technology Program (DSCRTP) has been collecting coral and sponge location data from hundreds of remotely operated vehicle (ROV) surveys. However, DSCRTP does not have a spatial representation of the area covered by each ROV while searching for corals and sponges in the deep-sea. A spatial representation would provide critical information to researchers and managers to understand where a survey for corals and sponges has happened, and where a survey is yet to be done in the deep-sea. Therefore, the goal of this study is to create a spatial representation of the ROV surveys that have been collected in Monterey Bay and Hawaii sections of the deep-sea.
