JON EYTHORSSON: Report on Sea Ice off the Icelandic Coasts, Oct. 1958 -Sept. 1959 The Icelandic coasts were jree of drift ice throughout the period. Only a few icebergs or belts of Greenland ice were sighted in the vicinity of the northwestern promontories. Distances are given in nautical miles. OKTOBER 1958. The average distance of ice boundary from Cape Straumnes tuas about 100 miles. 11/10 The boundary of ice was roughly runn- ing from 7000/2054 to 6830/2510 to 6750/2500 to 6715/2545 to 6740/2700 to 6730/3830 to 6807 /3015 to 6743/3030 to the coast at Aggas Island. The area N of 68° had mostly concentration of 8/10 small and 1/10 large floes, consisting of 60% winter ice and 40% polar ice with heavy riding and rafting. Many hummocks and light snow cover with refrozen puddles. Most of the area S of 68° had concentration of 3/10 brash and block, 1/10 small and medium floes and 3/10 bergs. There were many bergs throughout the area. 17/10 The boundary of drift ice was approxi- mately running from 7015/2015 to 6800/2500 to 6730/2830 to 6730/3100 to 6750/3130 to 6730/ 3230 to 6712/3145 to Aggas Islancl. No ice was sighted to the south of that limit. The average concentration within the area was 6/10 varying from 2/10 to 10/10. North of 68° all ice seemed to be polar with scattered arctic floes. About 9/10 of the area was covered. Many bergs within twenty miles off the Greenland coast throughout. 21/10 An Icelandic air plane en route from Mestersvig to Iceland observed about 40 miles wide area of close drift ice extending from Cape Brewster southwards along the 22° meridian W. NOVEMBER 1958. The average distance of the ice edge from Cape Straumnes was about 85 miles with nearest approach of 70 miles on Nov. 11. 11/11 The eastern boundary of Greenland ice was running from 6930/2030 to 6730/2518 to 6720/2447 to 6719/3015. The coverage along the boundary was mostly 6/10—9/10 consisting of brash and block, small and medium floes and young ice. All ice was polar with líght hummoc- king ancl continuous snow. There were few ice- bergs sighted. 15/11 The eastern boundary of ice was runn- ing from 7000/1940 to 6745/2520 to 6710/2800 to 6700/3000 to 6730/3120 to 6710/3230 to 6700/3200 to 6620/3335 to 6516/3637 to thirty miles S of Kulusuk to eleven miles S of Ang- magsalik to 6524/3843 to 6500/3845 to Aflands- hage. The concentration N of Kangerdlugsuak was mostly 10/10 consisting of small and me- dium floes and large floes. — In the area S of line from 6533/3525 to six miles S of Erik den rödes island to eight miles S of Kulusuk to ten miles S of Angmagsalik the concentration was 1/10 brash and block, 3/10 small and medium floes, plus less than one tenth slush. DECEMBER 1958. The average distance of ice limit from Cape Straumnes was about 110 miles. 13/12 The eastern ice boundary ran from 7153/2030 til 7000/1900 to 6930/2000 to 6750/ 2530 to 6630/3000. The concentration near the boundary was 6/10 in the south increasing to 8/10 north af 69° N. A polynya was sighted at 7117/2000 to 7107/1947 to 7056/2000 to 7107/ 2025 partially covered by newly formecl ice. — A few icebergs were sighted at 7000/1930. 19/12 The eastern boundary of ice was run- ing from 7030/1745 to 6953/1824 to 6837/ 2238 to 6822/2400 to 6805/2445 to 6734/2900 to 6717/3150 to 6630/3300 to 6606/3400 to boundary end at 6547/3530. Several icebergs were sighted at 6911/2050. The area from the eastern boundary to a line seven miles west of it had concentration of 1/10 to 5/10. the area bethveen seven and seventeen miles west of the boundary had conc. 43
