A custom-built observation frame (ROVOS) based on Ocean Module V8Sii ROV (Remotely Operated Vehicle) technology was launched from RV Meteor and towed along a 118 m transect in the southern part of the Garibaldi Fjord, in a depth of 92 m. The extreme barren sea floor is only home to only very few crustaceans.The instrument was equipped with three cameras with different perspectives: one HD camera (Kongsberg oe14-502, 720p50) pointed isometrically forward at an angle of 22.5° to the horizon, the second 4k camera (SubC Imaging Mk6, 2160p25) was oriented downward and an observation camera (Bowtech L3C-650-L, 240p24) provided a low-resolution view forward. Environmental data was recorded with a CTD (RBR Maestro), which included sensors for chlorophyll a, turbidity, oxygen, pH and PAR in addition to standard instruments for conductivity, temperature and pressure. Additional CTD data are available from water profiles (Schwalfenberg, in preparation). The position of the ROVOS was recorded with the ship's own Posidonia USBL. The global orientation with respect to magnetic north was determined with an internal IMU device. To determine the true image scale on the high-resolution footage, a series of reference lasers indicating 10 cm were used in addition to an altimeter (Tritech) providing acoustically measured heights from the SubC camera to the seabed (see metadata).
