Sea Level Fluctuations in Tórshavn
Preliminary Results
Bogi Hansen.
Introduction
The fluctuations of sea level and currents at the Faroe Isiands
make quite an interesting subject. The position of the Islands,
far from the continents, close to a supposed amphidromy and
in one of the key areas with respect to the overflow of cold
bottom water from the Norwegian and Greenland seas into
the Atlantic indicate the theoretical importance, while the very
strong tidal currents on the Faroese plateau make obvious the
practical importance. Fiowever to the authors knowledge very
little has been published on the subject, the highlight being a
paper by Adam Poulsen dating back to 1906. He analyzed the
tide in Tórshavn and his results are reproduced in table I.
The present study concerns itself with tide gauge measure-
ments made in Tórshavn for the most part of 1973. As the
work is still in progress, only preliminary results will be dis-
cussed. These include a tabulation of Harmonic constants and
some investigations into the influence of atmospheric pressure
on the sea level.
Data
The sea level registrations analyzed in this paper cover the
period: Jan l.st 1973 0000 GMT to Oct 19th 1973 2345 GMT
sampled at 15 minutes interval. The tide gauge was situated in
the harbor of Tórshavn and was owned and supervised by the
