2018 ROV video survey at NE Hatton Sill (Northern Labrador) aboard CCGS Amundsen (dive 67).

A remotely operated vehicle (ROV) video survey was conducted at the NE Hatton Sill location, at a depth of ~620 m in August 2018. The primary purpose of the ROV dive at this location was to obtain video-transect data for species composition determination, site characterization and depth distribution of corals and sponges, and to collect live and dead corals and sponges. Bottom type was mainly sand and gravel with occasional boulders. Semi-consolidated sand was observed at various points within the dive. Corals observed during this dive include Primnoa resedaeformis (including dead skeletons), soft corals, mushroom corals (e.g. Anthomastus sp.), Paramuricea sp., Radicipes sp., sea pens, sponges including Asconema spp. and Geodia spp.
