Abstract : BIRDS EYE 7-69 was a regularly scheduled Arctic Ocean Ice reconnaissance mission covering the North American sector of the Arctic Basin, including the Greenland Sea and Denmark Strait from 21 October to 5 November 1969. Ice observations were taken under daylight conditions in lower latitudes and in moonlight at higher latitudes. Three tracks were flown as planned; the remaining tracks were modified or cancelled owing to adverse weather or poor illumination. The ice edge east of Greenland was 15 to 25 nautical miles south of its normal position. Large amounts of new, nilas, and young ice lay behind the edge. New ridges were observed within the pack northwest of Alaska. Radarscope photographs of T-3 located near 85 deg 56 min N, 121 deg 51 min W are included. Russian ice station NP-17 sighted at 87 deg 30 min N, 11 deg 00 min E appeared to be abandoned. (Author)
