Vertical luminophore particle tracer profiles expressed as relative counts for replicate macrofaunal communities from the Western Barents Sea in summer 2017 and 2018
Macrofaunal mediated redistribution of optically distinct particulate tracers (luminophores) for intact communities from the western Barents Sea after 12 days incubation. Tracer profiles are quantified from stitched composite images of all four sides of each aquarium taken using a digital SLR camera housed within a UV illuminated imaging box. Counts are expressed as relative counts (proportion of the total). Samples were collected on cruises JR16006 and JR17007.

Counts were extracted from digital images with a resolution of 83 µm pixel-1 in 2017 and 74 µm pixel-1 in 2018. Images were cleaned using Adobe Photoshop CS6 to remove highly reflective dust particles, cloth filaments or other non-luminophore pixels.
Relative counts are calculated from stitched images of 4 sides of an aquarium except for stations B13 (aquarium #2), B14 (aquarium #4) and B15 (aquarium #3) in 2017 which were calculated from 3 sides of an aquarium following an unrecoverable file corruption on a subset of images during transfer.
