BIRDS EYE 5-69, 18 July-5 August 1969.
BIRDS EYE 5-69 was a regularly scheduled Arctic Ocean ice reconnaissance mission covering the North American sector of the Arctic Basin, including its adjacent seas and areas within the Canadian Archipelago from 18 July to 5 August 1969. Ice observations were made under daylight conditions. Adverse...
