OCTOBER 1967
No ice zuas reported in Icelandic xuaters.
Relatively strong NNIi-erly winds were blow-
ing along the east coast of Greenland resulting
in air temperatures considerably below average.
The amount of drift ice in the ]an Mayen
area and between Jan Mayen and Iceland was
greater than usual. At the end of the month
the edge of close pack ice was some 70 miles1)
off Kögur on the NW coast of Iceland.
NOVEMBER 1967
The amount of drift ice east of Greenland
increased greatly and became exceplional due
to unusually slrong NNE-erly uiinds and loiu
air and sea temperatures, but no ice reached
the coasts of Iceland.
The boundary of close pack at the end of
October and some three weeks later is shown
on Fig. 1 according to ice charts from the
British Meteorological Oífice. The amount of
ice between Greenland, Jan Maven and Spits-
bergen has apparently increased by approx.
50%, probably to a considerable extent be-
cause of freezing. Between Iceland ancl Jan
Mayen the increase was greater than shown on
the map due to open and very open pack out-
side the close pack. On the whole the extent
ot the ice was quite exceptional in November
and the British Meteorological Office stated
that there is some evidence that this was the
greatest extent in any November since 1876.

DECEMBER 1967
Some very open pack drifted to the coasls
of Northern lceland early in the month and
ice was reported in coastal waters 16 days. At
the end of the month the boundary of close
pack xuas some 20 miles N of Horn and Gríms-
ey but very open pack was closer to the coast
and extended to Tjörnes and Melrakkaslétta.

south. The following days, 0_10/i2, many ships
and some land stations reported single floes
or scattered ice near the north coast from
Horn to Melrakkaslétta. The conditions on
the 6th are shown on Fig. 2 according to ice
reconnaissance by the Coast Guard Aircraft
TF-SIF (hereafter referred to as SIF).
°/12 Leirhöfn reports: Drift ice sighted from
farms on the W coast of Melrakkaslétta. Some
floes ashore.
Flatey in Skjálfandi: Ice sighted 2 miles off
from NW to NE.
M/s Tungufoss reports: Some icebergs ob-
served 36 miles E of Horn.
