BIRDS EYE 9-66 21 NOVEMBER-11 DECEMBER.
BIRDS EYE 9-66 observations were scheduled to take advantage of optimum moonlight over the arctic basin. Overall ice concentrations in the arctic basin had reached a maximum of ten-tenths with vast floes being the predominant form and representing an increase in concentration over BIRDS EYE 8-66. Al...
