Description
Summary:Data collected by ice observers during Naval Oceanographic Office polar research flights known as BIRDS EYE missions are contained in this report covering the seventh mission of 1966. The ice data include distribution, stages of development, topography, types of water openings, number, and height of topographic features. Water opening data present the number, width, and orientation of water openings. The over-all effectiveness of the mission is included as an evaluation table. In comparison with BIRDS EYE 6-66, the sub-arctic areas showed considerable increase in concentrations. For example, the track from Keflavik to Thule increased in concentration two to three tenths. A slight increase in ridging over these areas was observed but was not significant because of its occurrence in the younger forms of ice. The area adjacent to the north Alaskan coast showed similar characteristics. Concentrations over the arctic basin showed a slight increase over those observed during BIRDS EYE 6-66. The number of water openings had correspondingly decreased promarily due to refreezing with medium winter ice.
