The seabed along the transect consists of sand and shells/shell fragments, becoming slightly gravelly in the NW. Fauna are dominated by echinoderms (brittlestars, urchins, starfish). Bivalves (including scallops) are also present, but not abundant. A couple of thornback rays are incompletely captured, occurring at the edge of the data between 300m and 400m from the SE end of the transect. A number of exposed boulders are present at the NW end, colonised by urchins, brittlestars and anemones. Water depth 54-68m.
