the exposure index. Further, aspect was
highly correlated with the axis. These re-
sults should be interpreted with caution due
to the low number and the limited geo-
graphical range of the sites. It is possible
that fjord effects and aspect were more im-
portant in this area than at other places in
the Faroe Islands. However, the resem-
blance of the ordination plot to that for the
other stations suggested that the same fac-
tor was underlying the first axis in both or-
dinations. For the nine stations all situated
in one fjord system, the fjord index may
have been a more reliable estimator of ex-
posure than the exposure index. The appar-
ent effect of aspect may have been due to a
positive correlation with the fjord index —
in that there happened to be more south-ori-
ented stations farther into the ijord.

The field investigations were part of the FARCOS pro-
ject, supported by Amerada Hess, BP, Conoco, Mobil,
Phillips Petroleum and Texaco and of the large BioFar 2
project, supported by the Carlsberg Foundation. The
data treatment was conducted at the Marine Biological
Station, University of Bergen, partly financed by Alpha
Environmental Consultants, NoBaLes (Norwegian Bar-
ents Sea Exploration Co-operation) and OLF (the Nor-
wegian Oil Industry Association). We are also grateful
to Dr. Eivind Oug and Prof. H. John B. Birks, who
helped to improve our understanding of the statistical
methods involved and to cand. scient. Mikaela Kruskopf
for comments on the manuscript.
