Sample Collection

Specimens of an abundant species of small ophiuroids or brittle star were collected, possibly Ophicantha bidentata (see below).
They will be identified on return to the laboratory.

Ophiuroids

Sediment samples and ROV transects were taken to investigate the disturbance cause by the drilling. See diagram below:

Amphipod

An amphipod Cleippides quadricuspis.

Asteroid

Pontaster tenuispinus.

Cerianthid

Cerianthid in the drill spoil.

Crinoid

A stalked crinoid or sea lily (Bathycrinus carpenteri) with a soft coral, likely Gersemia sp. using the base as a hard substrate for attachment and an epimerid amphipod near the top of the stalk.
