# The pattern on the pattern's own query: a resource observation for the year 2004 whose abundance
# level is 'Low abundance'. The resource is the Northeast Arctic cod stock, the species is Gadus
# morhua, and beside it stands the survey observation it rests on - made by an ICES working group,
# over the Barents Sea, with a spawning-stock biomass figure as its result.
