area off the boundary. The concentration
throughout the entire area of observation 'was
s/io to 8/10 with heaviest concentration within
30 miles off the Greenland coast.
In the period t/i^ — 2ð/i2 single icebergs were
reported off the NW-coasts between 6646/2300
and 6620/2430.
JANUARY 1956.
The average distance of t.lie boundary from
S traumnes was about 80 miles with nearesl
approach of 65 miles at the begin of the month.
7/i Pack boundary extended from 6515/3300
to 6735/2305 to 6950/1730 to Kap Tobin. The
concentration within 30 miles off the Green-
land coast consisted of 2/io brash and block
and 6/g small and medium floes or 8/io field
ice (in certain areas). The coverage in the re-
mainder of the area was 2/io brash and block,
2/io small and medium floes and s/io field ice.
13/i The boundary extended from 6500/3845
-6500/3535-6630/2810-6730/2600. The con-
centration from 6500 til 6530 consisted of 7/io
brash and block, and t/io small and medium
floes. Off the pack boundary the coverage was
t/io brash and block and //io small floes.
18/i The boundary was from 6930/2000—
6640/2835-6650/3000-6535/3120. The con-
centration consisted of 8/io to Gio coverage in
all areas observed, with scattered broken ice off
the pack boundary north of 6830 N.
26/i The pack boundary from 6830/2222—
6750/2340-6750/2425 to 6648/2820. Concentra-
tion: 8/io to !/ io coverage 10 miles off the
pack boundary and 5/io to 8/io 10—15 rniles
within the boundary.
Winter ice in Icelandic fjords and harbours.
During a cold spell in January many small
fjords and sheltered harbours became covered
by new ice. Towards the end of the month the
ice was 5 inches thick in the harbour of Reykja-
vík and 5—10 inches on Skerjafjord. At Breida-
fjord, the Álftafjord, Hvammsfjord and the
small northern fjords were closed by winter ice.
On the last day of the month and Februarv
1 all this ice was swept away by a severe south-
erly gale with rain and mild weather.
A single iceberg was repeatedly observed
slowly drifting from pos. 6630/2100 towards C.
Horn. On the 22nd it was only 18 miles NE of
C. Horn, but three days later it was drifting
into the Húnaflói and sighted SE o£ Kjörvogur.
FEBRUARY 1956.
The average distance of the pack boundary
from Straumnes was about 90 miles with
nearest approach of 65 miles.
4/o The boundary extended from 7015/1800
to 6927/2200 to 6830/2300 to 6729/2805 to
6608/3020 to 6520/3250. Concentration off the
pack boundary 4/io to 8/io puddled floes
throughout the entire area.
12/o. The boundary observed by radar from
6520/3300 to 6650/2700 to 6727/2345 to 6830/
2300 to 6930/1830. Concentration 5/io to 7 / m
ten miles off the pack boundary, with the hea-
viest concentration north of 67—00 N.
18/2 The pack boundary observed from 7000/
2130 to 6840/2400 to 6725/2800 to 6555/3345
to 6555/3430. Concentration up to 8/io 130
miles off the pack boundary in the northern
area and 5/io to 8/io 10 miles off the bound-
ary in the southern. There were widely scatter-
ed bergy bits, brash ancl block up to 80 miles
offshore north o£ 6730 N.
23/2 The pack boundary was observed by
radar from 6800/2400 to 6700/2700 to 6700/
3000 to 6636/3230 to 6615/3145 to 6525/3335
to 6515/3600.
MARCH 1956.
The average distance of the ice edge from
Straumnes was about 80 miles, the nearest
approach 65 miles.
8/a The pack boundary was observed by
radar from 6825/1800 to 6817/2000 to 6745/
2200 to 6703/2525 to 6602/2700 tö 6557/2900
to 6520/2930 to 6429/3115. No determination
of coverage. Distance of the ice edge from

13/3 The ice boundary was observed by radar
from 6913/1952 to 6718/2748 to 6735/2940 to
6703/3120 to 6536/3235. Distance from Straum-
nes about 95 miles. Many bergs, growlers and
belts were observed along the northwestern ex-
tremities.
