Abstract : BIRDS EYE 3-68 was a regularly scheduled Arctic Ocean ice reconnaissance mission covering oceanic areas south of 81 degrees between Greenland and Norway from 21 May through 10 June 1968. Ice observations contained in this report were made under daylight conditions with very poor flying conditions due to weather during the first two weeks of the mission. Approximately 65 percent of the ice edges were located by radar. The extreme southern limits of the ice edge northeast of Iceland exceeded the maximum limits depicted in the 'Oceanographic Atlas of the Polar Seas' (HO Pub. 705). Composite ice charts included for two periods reveal a dramatic change in ice conditions north of Iceland. A large area of very open pack was observed in the vicinity of Scoresby Sund. Sea surface temperatures were recorded with an airborne radiation thermometer in an area east of Iceland and during transit to and from the ice pack. (Author)
