FIGURE 1. Equipment used for in situ observations between 50–550 m during the AAMP expedition to the Marquesas. a) R/ V Braveheart, 39 m, at Fatu Hiva Island. The ROV is on the stern, under the gantry crane; the control cabin and remote video processing equipment are in the grey container, on the upper deck (photo J. Poupin); b) ROV Super Achille in its cage during a recovery operation. Organisms collected with the articulated arm are stored in the iron basket visible on the side of the ROV cage; the leash that links the cage to the ROV is 70 m long and it is wound on top of the cage (photo P. Chevaldonné); c) ROV out of its cage during a pre-dive at stn 19 (photo T. Pérez); d) Screen photograph taken during dive at stn 25, showing information available for each dive: course of R/V, latitude, longitude, depth, station number, island (photo COMEX).
