Abstract:
A total of eight deployments of an autonomous baited camera lander were conducted at the Cabo Verde Abyssal Plain (tropical East Atlantic, Lat. 14.72, Lon. -25.19, Water depth ~4200 m) using either Atlantic mackerel (Scomber scombrus, n=4) or Patagonian squid (Doryteuthis gahi, n=4) bait, to photograph organisms attracted to the bait over roughly 24 hours. The deployments took place during the iMirabilis2 campaign in August 2021 from the research vessel Sarmiento de Gamboa. A deep-sea time lapse camera system with an oblique view of the bait plate (12 cm x 45 cm) and surroundings took a picture every 150 seconds. The bar attached to the bait plate is 6 cm wide. The camera was located about 120 cm above the seafloor with an oblique view of 40 degrees (assuming straight down in 0 degrees). Annotations were performed in BIIGLE software (Langenkämper et al. 2017) on every second photograph, providing the morphospecies group label (or 'No ID' if to morphospecies level was not possible) and the taxonomic hierarchy to a level of best confidence for each annotation. Annotations were rectangular in shape, enclosing each individual so that the centre of the annotation was roughly the centre of mass, and the points of each rectangle corner are provided in pixels (x,y) where the lower left corner of the picture is 0,0. Images were 6000 pixels in width and 4000 pixels in height.

Comment:
Taxonomic hierarchy of annotation: Morphospecies code with three letter and two numbers (XXX_00, for example COR_01) correspond to an identified morphospecies (see morphospecies). A morphospecies code is not always present, in that case the hierarchy shows the identification to a more general taxonomic detail. The morphospecies code is not always the end of the taxonomic hierarchy, sometimes an extra distinction was made (e.g. juvenile? or a colour). Organisms with an 'Unknown' annotation were thought to be an organism but no taxonomic identification could be made. If an individual could not be assigned to a morphospecies this value is set to 'No ID' and information on the best taxonomic detail can be found in the taxonomic hierarchy column.
