This taxonomic atlas illustrates the demersal and benthic invertebrates and fish observed in video transects made from 378 to 2765 m water depth in the rugged Southern California Borderland. Many of the images show fauna on mineral-rich substrates (ferromanganese crusts and phosphorites) associated with banks, ridges, knolls, escarpments and seamounts.  Images were collected in 2020 on E/V Nautilus as part of NA124 and in 2021 with the R/V Falkor as part of FK210726.
