BIRDS EYE 4-67, 10 - 22 AUGUST 1967.
Abstract
Data collected by ice observers from the U.S. Naval Oceanographic Office covering the fourth BIRDS EYE Arctic Ocean ice reconnaissance mission of 1967 (BE 4-67) are contained in this report. BIRDS EYE 4-67 covered the maximum limits of the ice pack between 11 and 22 August 1967. Observations were collected under daylight conditions with an overall 93 precent effectiveness. Boundaries were obtained by radar throughout the mission. The ice cover generally consisted of eight- to nine-tenths arctic pack. Young polar with younger stages of ice development was noted throughout. Only two significant leads were observed; one along the northeastern coast of Greenland and an ice-free lead along the western edge of ice island T-3. Ice island T-3 was located twice, and voice communication was established on each flight. Two Canadian ice islands were also located: WH-1, west-northwest of Banks Island, and another, believed to be WH-4, sixty miles west of Banks Island. North of the Alaskan coast the ice was heavily covered with dirt, making determination of its age nearly impossible. The ice boundary along the Alaskan coast was farther southward than it was during BIRDS EYE 7-65 (9 through 26 August 1965) and BIRDS EYE 6-66 (6 through 28 August 1966). (Author)
