Climatological monthly ocean-surface temperatures obtained from the National Center for Atmospheric Research and from Fleet Numerical Weather Central are merged and interpolated onto a 1-deg global grid. Monthly distributions of the main ice packs of the Arctic and Antarctic are digitized from Fleet Weather Facility ice charts and Navy atlases and then incorporated into the global arrays. Machine-analyzed maps show the 12 monthly distributions, and maps and tabulations of averages of these data for the months of February and August are shown on a global grid of 4-deg latitude times 5-deg longitude. 30 pp. Ref.
