As the ROV reached the end of its umbilical at 2557 m without reaching the sea floor it travelled 500 m mid-water to reach the side of the canyon. The sea floor on this slope is that of sandy sediment; the fauna consists of holothurians, including some Mesothuria intestinalis and echinoids including a small white cf. Echinus sp. and Spatangus sp.

COMPOSITE VIDEO 17:26 [1] the whole transect occurs on mud with flocculent detritus apparent on its surface. Adult Peniagone sp . holothurians dominate the first half of the transect, with Acanella arbuscula also sparsely distributed. Many of the other epifaunal species present similar to the lower bathyal A. arbuscula biotope, but there is only a low density of A. arbuscula. 01:58 - 02:42 ROV stops/goes slow. 09:07 - 09:16 ROV stops. 09:22 - 13:49 ROV moving jerkily and diagonally to the left, before resuming normal forward motion.
