Annotations of species recorded on video by Remote Operated Vehicle (ROV) during dives performed in the Faial-Pico Channel in the Azores archipelago, Portugal. Videos were recorded between 80 and 250 meters depth.
Deep-sea sampling in 2009 onboard the R/V Sarmiento de Gamboa in the three Mediterranean basins. A combination of 2 samplers was used to collect the benthic megafauna: an otter-trawl Maireta system (OTMS) and an Agassiz dredge. The OTMS is a 1-warp benthic otter-trawl designed to work seamlessly on high depth grounds: its stretch mesh size at the cod-end is 40mm, with an outer cover of 12mm, to allow retrieval of small-sized fractions of megafauna. The net total length is 25m, with an horizontal opening of 12.7m and a vertical opening of 1.4m. Trawls were conducted at 2.6 to 2.8 knots. The Agassiz dredge had a 2.5 m horizontal opening and 1.2 m vertical opening, a net mesh size of 12 mm, and was trawled at 2.0 knots.
Annotations of benthic sessile and mobile species recorded on video by Remote Operated Vehicle (ROV) during dives performed in the Condor seamount, located 10 nm SW of Faial Island, in the Azores archipelago, Portugal. Videos were recorded between 180 and 1100 meters depth.
