BIRDS EYE 4-69 was a regularly scheduled Arctic Ocean ice reconnaissance mission covering the North American sector of the Arctic Basin, including its adjacent seas and the Parry Channel in the Canadian Archipelago from 26 May to 15 Jun 1969. Ice observations were made under daylight conditions. Low overcast existed during most flights, but good visibility allowed viewing of the ice pack on numerous occasions. In the Greenland Sea, extensive ice coverage as observed on BIRDS EYE 3-69 (23 March -22 April) continued to exist northwest of Iceland; however, conditions approached normal elsewhere. In Parry Channel, ice conditions since BIRDS EYE 1-69 (23 January - 7 February) improved from Baffin Bay to Resolute with little change westward. The fast ice boundary along the north Alaskan coast as well as a recurring polynya which had recently formed south of Banks Island were recorded. (Author)
