Highlights: 00:21:18 Chimaera 00:34:50 Octocoral - Anthomastus & sea fans 00:49:50 Compass anemone

A feature of this dive is a strong current with heavy marine snow. The seafloor consists of areas of soft sediment with occasional rock outcrops and stony coral clumps. The faunal community is the same throughout namely, Paramuricea sp., ophiuroids, cerianthids, sea pens and Anthomastus sp. Other less frequently encountered species include the black corals Stichopathes sp., Stauropathes sp. and Bathypathes sp. and the sea pen Pennatula aculeata. A steep ledge of carbonate substrate is colonised by encrusting sponges and Solenosmilia.

START VIDEO [00:00:00]/10:18. The whole transect occurs on mud with flocculent detritus apparent on its surface with frequent patches of carbonate and boulders. Heavy marine snow throughout the entire dive. [00:00:00] [1] The transect starts on a moderate continental slope with soft muddy sediment dominated by Ophiumusa lymani. [00:01:50]-[00:08:00] The ROV stops for core sampling. The ROV moves again. [00:11:00] [2-3-4] O. lymani co-dominate the transect with Anthomastus grandiflorus and Paramuricea sp., which co-occur until [00:20:00]. [00:20:00] [5] Pennatula aculeata, A. grandiflorus and O. lymani co-dwell on muddy sediment. [00:25:00] [6] Cerianthid anemones dominate muddy sediment. [00:35:00] [7] soft corals dominate the site. [00:46:00] [9] The slope becomes steeper, pebbles and cobbles become more common, ophiuroids are generally dominant on soft sediment, while encrusted sponges occupy the hard substrate. [00:59:00] [11] [12] [13] Patches of pebbles and cobbles are scattered, while mud sediment becomes more spread dominated by O. lymani and Caridea sp. The sediment is muddy with many Acanella arbuscula [01:04:00] The ROV reaches the summit where flocculent detritus are particularly abundant and the resolution of the video is not clear enough to spot species. The ROV dives in the water column for a while. [01:28:00] The ROV goes down the carbonate cliff and recording the water column. [01:32:00] The ROV reaches the summit of another carbonate mound with carbonate and mud sediment dominated by Paramuricea sp. until the end of the dive. VIDEO ENDS AT [01:42:42]/12:01.
