Although there are a fair amount of pa-
pers about the marine benthic fauna in
Faroese waters, there are no published data
from the Faroe Islands on species compo-
sition and quantity of the fauna. There are
although a few reports, mostly from Skála-
ljørður, and a few from other ijords and a
single report comparing two sites on the
Faroese shelf.
Skálaíjørður is a sillfjord with low oxy-
gen concentrations in the near bottom
water in the deeper parts of the ijord in late
summer/early autumn. The samples taken
at Glyvrar (10) in Skálafjørður are from
45-meters depth and the fauna is therefore
not under influence of low oxygen concen-
trations (Gaard et al. 1990).
Nørrevang (1990) reported from an in-
vestigation on Faroese sillfjords. Jørgensen
