The substrate of the canyon floor appears very fine, soft sediment continues up the canyon flank before transitioning to exposed bedrock with small terraces and overhangs. This slope is very steep on occasion. From 2000 m depth the slope incline shallows, from here the substrate is soft to the top of the canyon. Heavy marine snow is an aspect of this canyon. Asteroids, echinoids, sea pens, black corals including Bathypathes sp. are common throughout the canyon. Brisingids, mobile and stalked crinoids, hydrozoans and cup corals and hormathiid anemones are present here sporadically. Some of the less conspicuous fauna include shrimp, hermit crabs, glass sponges and encrusting sponges.

START VIDEO [00:00:00]/20:01 [1] The transect starts on mud with solitary cup corals an Ophiomusa lymani [00:03:00] [2] a brief patch of cobbles and boulders is mainly dominated by O. lymani [00:04:00] [3] mud mainly hosting again O. lymani, but patchy white echinoids (OTU559) are also present. [00:12:00] [4] the first area of escarpment, sloping carbonate is mainly colonised by stalked crinoids, but also sponges and corals along with other scattered fauna. Some ledges are heavily sand veneered with cobbles and boulders providing the main substrate. Extended flatter carbonate shelves are mud veneered with O. lymani but corals often still present (e. g. Stauropathes arctica) attached to the underlying carbonate. [00:25:00]-[00:26:00] stop for imagery (Actinernus sp.). [00:27:00]-[00:29:00] stopped/moving slow for imagery. [00:33:00] [5] rippled mud with rare pebbles, scattered fauna, mainly cf. Anthoptilum sp . (OTU1107) sea pens. [00:37:00] [6] horizontal carbonate with mud veneer, mixed corals attach to the underlying carbonate, especially Chrysogorgiidae sp . (OTU1008). Paramuricea sp . and Acanella arbuscula are also present along with cup corals, and O. lymani. [00:39:00]-[00:40:00] Stopped for imagery. [00:42:00] [7] The mud again deepens with cf. Anthoptilum sp . sea pens dominating, along with A. arbuscula and solitary cup corals. [00:57:00]-[01:05:00] Stopped for two pushcore samples. [01:17:00]-[01:19:00] stopped for imagery.
