JON EYTHORSSON:
Report on Sea Ice off the Icelandic Coasts, Oct. 1963 -Sept. 1964
The Icelandic coasts were free of drift ice
throughout the period. In January, however,
some loose drift ice and isolated strips were
observed at the northwestern fishing banks.
The winter months 1963/64 were generally
mild ancl favourable, while the summer was
cool.
Below are quoted the monthly normals (1931
—1960) and the monthly means for Cape Horn
and Stykkishómlur.
