BIRDS EYE 2-67 was a merger of two regularly scheduled Arctic Ocean ice reconnaissance missions, enlarged to cover the maximum limits of the winter pack ice between 15 March and 19 April 1967. Two areas not usually surveyed were the Barents and Bering Seas. Ice observations contained in this report were made under daylight conditions with an overall 98 percent effectiveness. Approximately 90 percent of the ice boundaries were obtained by radar. In the Barents and Bering Seas the ice boundary was far north of its normal position; significantly greater amounts of younger ice forms were noted and ice concentrations were less than normal. During the mission the pack ice boundary generally occurred north of ice atlas positions for this particular time period. Overall ice concentrations were below normal for all areas surveyed, except a sector north of the Alaskan coast between Point Barrow and the Beaufort Sea, where ice conditions were more severe than usual.
