BIRDS EYE 6-66, 6-28 AUGUST 1966.
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 sixth mission of 1966 (BE 6-66). The manner in which these data were recorded is discussed. The percentage of effectiveness of thi...
