Abstract : BIRDS EYE 4-68 was a regularly scheduled ice reconnaissance mission covering the Western Hemisphere portion of the Arctic Ocean and adjacent seas between 1 and 16 July 1968. Ice observations contained in this report were made under daylight conditions. Flying conditions were excellent except to the northeast of Greenland and generally on the northernmost parts of the tracks. The position of the ice edge in the East Greenland sea near Iceland indicated a rapid retreat from its observed position during BIRDS EYE 3-68 (21 May - 10 June). A well-defined north-south lead existed in the western Chukchi Sea. Ice cover was minimum along the Alaskan coast. Composite ice charts are included in this report for two periods to show ice conditions and changes which occurred off the north coast of Alaska and throughout the Arctic Basin over a 5- to 6-day period. Sea surface temperatures were recorded with an airborne radiation thermometer in an area to the east of Iceland and in transit to the ice pack. (Author)
