SUMMARY
Direct Current Measurements in the Sea
Measurements in Faxaflói
Auguat 1966
by Svend-Aage Malmberg
Marine Research Institute, Reykjavik, Iceland.
Few direct current measurements have been made in the sea around Iceland.
Scientists from several countries have made measurements in the oceanic areas
east, south and west of Iceland, but the shelf areas have been neglected. The
only measurements in the shelf areas known to tlie author were made in 1924
at the 25 m level (2) and south of Iceland in the surface layer in 1960 (3).
During August 12—13 1966 direct current measurements were rnade at one
station in Faxaflói (Fig. 1). These measurements were carried out in connection
with detailed oceanograpliic-biological studies in Faxaflói during the period
February 1966 — March 1967. The current measurements were made with Ek-
man Current Meters at 20 and 50 m depth over a period of 36 hours, with a
total of 72 measurements at eaclt depth. The results obtained were as follows
(See Table):
a) at 20 m depth the residual current was found to be 8.7 cm/sec with a dir-
ection of 350°, and at 50 m depth it was founcl to be 5.8 cm/sec with a
direction of 334°. These results are supported by the density distribution in
the uppermost 30 nt (Fig. 5), obtained from temperature and salinity data
collected during August 9—11.
