The substrate at this site is that of soft, featureless sand on a steep to very steep incline. The echinoid Echinoidea sp. 4 (from Howell & Davies 2010), is the most common species throughout; grenadier are present in low numbers. Small dense patches the elpidiid holothurian occur between 1660 m and 1630 m depth. Large burrows, one of which is occupied by a galatheid are first observed at 1630 m. At the top of the slope two species of sea pens Umbellula sp. and Kophobelemnon sp. are present.

START VIDEO [00:00:00]/12:29 [1] The whole transect was spent on muddy substrate with the urchin Phormosoma placenta dominating the epifauna (at least one every [00:10:00]). [00:13:00] [2] While the urchins and mud continue, there this area of the transect encounters multiple patches of thousands of juvenile holothurians (probably from the family Elpidiidae). These continue until [00:25:00] [3] return to P. placenta dominated mud slopes. Stops for imagery at [00:38:00]-[00:39:00] (Phormosoma), [00:59:00]-[01:01:00] (Phormosoma/Umbellula), [01:05:00]-[01:06:00] (octopus), then [01:07:00] stop to take a pushcore before END VIDEO [01:15:00]/13:44.
