Vertical luminophore particle tracer profiles expressed as relative counts for replicate macrofaunal communities from the Western Barents Sea in summer 2017 and 2018
GB/NERC/BAS/PDC/01370

Summary

Abstract:
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.

Funding was provided by 'The Changing Arctic Ocean Seafloor (ChAOS) - how changing sea ice conditions impact biological communities, biogeochemical processes and ecosystems' project (NE/N015894/1 and NE/P006426/1, 2017-2021), part of the NERC funded Changing Arctic Ocean programme.
