The seabed along the transect consists of sand and shells, becoming increasingly gravelly to the NE. Fauna are dominated by echinoderms (brittlestars, urchins, starfish); these are more numerous in the second (NE) half of the transect where brittlestars are extremely abundant, carpeting the seafloor in some places. Fish (rays and dogfish) can also be seen on occasion along the transect.
