JON EYTHORSSON:
Report on Sea Ice off the Icelandic Coasts, Oct. 1962 - Sept. 1963
Scattered drift ice invaded Icelandic waters
off the northwestern promontories in January
and February and for most of the period the
ice margin or big fields of drift ice were un-
usually close to the NW-ern coasts. The ice did
not impede sailing round Cape Horn but caused
some inconveniences to fishing boats. However,
the winter was generally mild and favourable
in Iceland, but the summer was cool and really
unfavourable towards the end. Below are given
the monthly normals (1931—1960) and the means
1962/63 for Cape Horn and Stykkishólmur the
latter being the classic climatological station of
Iceland.
