In 1996, Halldis Ringvold, M.Sc. candi-
date, wrote her M.Sc. thesis (in Norwegian)
on the “Identification and Distribution of
Seastars in the Faroe Waters” at the Univer-
sity of Science and Technology (NTNU) in
Trondheim, Norway (Ringvold, 1996).
The present report is based mainly on the
chapter in that thesis discussing the record-
ing of the species in the region.
Results
In the systematic list below, the following
information is given for each species: the
valid name with author and publication
year, relevant synonyms, reference to good
descriptions of the species, previous
Faroese records, the BioFar (and to some
extent also BioFar 2) stations where the
species was found, area descriptions (Fig.
1), dominant bottom sediments in the areas
where the species was found, dominant wa-
ter mass at the same stations, depth range,
measured temperature range or estimated
temperature range of the near-bottom water
based on data from a database created by H.
Westerberg (in Nørrevang et al., 1994),
general depth range of the species in the At-
lantic Ocean, and its general distribution.
Relevant synonyms are taken from Clark
and Downey (1992). The number in paren-
theses after a station number refers to spec-
imens kept, when known. The information
on general distribution is taken mainly
from Clark and Downey (1992).
