Complementary Gravity Observations
in the Faroe Islands
By Svend Saxov1)
Abstract
During the North Atlantic Seismic Project in 1972 possibi-
lities occurred to establish some 130 complementary gravimeter
stations in Vágar, Streymoy and Suðuroy.
Because problems arose in connection with the stability of
the temperature of the Worden Master Gravimeter employed,
a special investigation with regard to cooling and heating of
the gravity meter was undertaken.
The Bouguer anomalies including topographic corrections are
depicted at the maps and the isogal picture is discussed. It is
concluded that the Faroe Islands are considered as one unit
gravimetrically.
In the summer of 1972 the Laboratory of Geophysics at
Aarhus University participated in the North Atlantic Seismic
Project (NASP), which was headed by Professor, Dr. M. H. P.
Bott at Durham University, Great Britain.
During the NASP campaign opportunities occurred to carry
out complementary geophysical investigations, e. g. K. Over-
gaard Hansen & V. Halskov Søndergaard (1973) made a
systematic study of the magnetic susceptibility of the basaltic
rocks. Furthermore, a series of detailed gravimetric observations
