Biology Catalog

The National Science Foundation’s Ocean Observatories Initiative (NSF-OOI) has installed a network of instruments, undersea cables, instrumented moorings, and mobile platforms that spans the Western Hemisphere. The Regional Cabled Array monitors a wide range of sites across the Juan de Fuca Plate, including Axial Seamount, Southern Hydrate Ridge, Slope Base, and the Oregon shelf (where it overlaps with the Endurance Array). This catalog has high definition images and videos that provide spectacular views of the organisms found at these sites, collected over years of Cabled Array expedition cruises.

This catalog is designed as a growing archive, and input from knowledgeable individuals will help to improve the quality of the information presented here. Have an addition or revision? Get in touch via our Contact Page.

A subset of images from the Biology Catalog (generated May 2024), containing a wide range of fauna observed at RCA sites can be found here.
