This marine climatological atlas was compiled as an aid for regulatory agencies, structural designers, operational planners, and marine scientists. Ice, wind, waves, air and sea surface temperature, wind chill, freezing spray, precipitation, cloud, visibility, flying weather and sea surface pressure are analysed. Contour maps and graphs are produced for various areas in and around the Beaufort sea depending on data availability. Four marine sub-areas were profiled in more detail as were six coastal land stations. observed data sets include rig/ship data from Dome Petroleum Limited, ships-of opportunity, land stations, ice cover and surface pressure. The uses and limitations of the data sets are briefly outlined. -- abstract.
