Table 4. Frequently occurring algae that werefound at a minimum of 33% ofthe localities in any one ofthree
exposure groups. These were defined according to the biological exposure values (BEV) into E (exposed = 0-
2.75), M (moderately exposed = 3-5.75), and S (sheltered = 6-9). Occurrences ofspecies in % oflocalities within
each exposure group are given as 1 = 1-33%, 2 = 34-66%, 3 = 67-100%.

part of Norway, which has a mean summer
temperature in August of 10.4°C (Midttun,
1975), actually resembled observations in
the Faroe Islands (Árrestad and Lein,
1993).
On the moderately exposed shores of the
Faroe Islands, Lomentaria articulata grows
gregariously, as also recorded by Børgesen
(1905). The distribution of this species,
which is rare on the west coast of Norway
(Haugen, 1968), appears to be correlated
with the relatively warm Atlantic water in
