Report on Sea Ice off the Icelandic Coasts in Oct. 1954-Sept. 1955
The Icelandic Coasts were jjractically free of
Sea ice throughout the period. In March some
scattered drift ice approached the northwestern
coasts for a few days and single icebergs or
floes were now and then observed near the
coast.
Distances are given in nautical miles.
OCTOBER 1954.
The nearest approach of the ice edge from
Straumnes was abaut 120 miles.
11 /10 The ice boundary was observed ex-
tending 10 to 20 miles along the Greenland
coast from 7030/2200 to 6830/2530 to 6824/2430
to 7006/1912. Clear shore was observed from
7030/2200 to K.Turnier. Ice concentration about
7/io- An iceberg at 6524/3230 was estimated to
be 300 ft high.

Brewster to 6700/3300 to 6700/3230 to 7000/-
2130. The shore clear from K. Brewster to
6700/3300. Ice concentration consisted of 5/io
brash, 2/i0 small floe and i/io large floe. Many
icebergs, estimated 100—400 ft, at 6536/3430
and 6700/2930.

13/n Ice edge observed from K. Dan to
6430/3700 to 6812/2400. Concentration 2/io

S tr aum n e s was about 100 miles..
4/12 Ice boundary from 6648/3400 to 6930/-
1900. Concentration 8/i0 brash and 2/10 small
and medium floe.
c/i2 Ice boundary from 6600/3300 to 6900/-
2100. Concentration within 2/i0 brash, 5/i0
small and 3/i0 large floe = 10/i0. Sixty per
cent clear shore from K. Hodgson to Iv. Steen-
strup.
10/12 The ice edge was at 6630/3000, about
100 miles off K. Gustav Holm.
JANUARY 1955.
The average distance of the ice edge from
Straumnes was about 95 miles, the nearest
approach about 80 miles.
7/r Ice boundary from 7000/1800 to 7030/-
2200, 6400/4000 to 6500/3500. Concentration
