Abstract : Data collected by ice observers during Naval Oceanographic Office polar research flights known as BIRDS EYE missions are contained in this report covering the third mission of 1966. The ice data include distribution, stages of development, topography, types of water openings, and ice boundaries. Ridge counts provide geographic distribution, number, and height of topographic features. Water opening data include the number, width, and orientation of water openings. The overall effectiveness of the mission is included as an evaluation table. The majority of water openings in the polar basin were covered with younger types of ice, although more open water was evident than was observed on BIRDS EYE 2-66. Ice concentrations were near ten tenths in the polar basin; lighter concentrations were observed in Alaskan coastal waters. Weather conditions were excellent, and the entire mission was very effective. BIRDS EYE flight tracks are generally repeated over the same areas to maintain continuity. The tracks cover the Arctic Basin and penetrate all the bordering waters with the exception of the Laptev and Kara Seas. The aircraft is an EC-121-K radar-configured Super Constellation manned by the Oceanographic Air Survey Unit based at the Naval Air Station, Patuxent River, Maryland. (Author)
