REYÐÆTI AV SLAGNUM MYSIDACEA A LANDGRUNNINUM
present between the warmer AW and the
colder NW. AI, of which several types can
be distinguished, is formed north of the
Arctic (or Polar) front in the Iceland and
Greenland Seas. From the areas of genera-
tion AI sinks and spreads to the northern
slope of the Faroe-Iceland Ridge which it
follows towards the Faroe plateau and into
the Faroe-Shetland Channel. In the Faroe
area this water usually has a temperature
between 1.5and3.5 °C.
Water with temperatures between 3.5
and 7.0 °C is a mixture of AW and AI.
Colder water with temperatures between 0
and 1.5 °C found north of both the Faroe-
Iceland Ridge and of the Faroe plateau, and
in the Faroe-Shetland Channel is a mixture
of AI and NW. Water of the same tempera-
ture range south of the Faroe-Iceland Ridge
is a mixture of AW, AI and NW.
For each species in the systematic list be-
low the following information is given: the
valid name with author and publication
year; synonyms when relevant; reference to
a good description of the species; previous
Faroese records; the BIOFAR and BIOFAR
2 stations where it was found; area descrip-
tions (Fig. 1); depth range; measured tem-
perature range or estimated temperature
range of the near-bottom water (based on
data from a database created by H. Wester-
berg, in Nørrevang et ai, 1994); the type of
water mass in which the species was caught
(identified by H. Westerberg, in Nørrevang
et al., 1994); and short notes on the distri-
bution and the depth range of the species in
the Atlantic Ocean. Data on the distribution
and the depth range of the species in the At-
lantic Ocean are taken from the monograph
on the British Mysidacea by Tattersall and
Tattersall (1951) and the World List of the
Mysidacea by Mauchline and Murano
(1977). Newer results adding to the geo-
graphical distribution and depth range are
referred to. The habitus drawings presented
are from Tattersall and Tattersall (1951).
