Data collected by ice observers from the U. S. Naval Oceanographic Office on polar research flights known as BIRDS EYE missions are contained in this report covering the tenth mission of 1965. The manner in which these data were recorded is discussed. The overall effectiveness of this mission is included in an evaluation table. The polar basin ice pack consisting essentially of vast floes remains at ten tenths concentration. Big floes were secondary. Ice ages remained predominantly arctic pack with some young polar and the other younger stages. A significant decrease in the number of water openings was noted with virtually all openings refrozen. There was a significant increase in the number of larger openings between 82 degrees N and 89 degrees N in the Lincoln Sea. An increase in roughness of the topography was noted with the most significant change between 86 degrees N and 89 degrees N. Flying conditions were good. Author
