This is some of the information which our Arctic Traffic Control would need to have. The SEASAT program will eventually consist of a number of satellites covering the majority of the globe. It is expected that the fully operational program, consisting of several multi sensor space craft together with ground data handling stations will be providing scientific and commercial information by 1985. Through SEASAT, a good insight into the various global and regional climatic trends and variations can be determined thus providing the potential for accurate long term weather forecasts.

People living in southern style cities and towns, or communities continuing to exist as best they can, developing for the most part in make shift fashion with few creature comforts other than telephone and television? - or people living in sophisticated sub-surface habitats, underground and underwater, and above the ground in modern city-like conditions under astrodomes?

Radiotelegraph A-I morse code is used extensively. HF Radio facsimile broadcasts covering the Arctic are operated from Edmonton and Halifax giving marine weather and ice advisory and forecast information. In the past communications problem areas frequently encountered by ships operating in the Arctic have included: (a) HF radio frequency interference caused by congestion; (b) Poor propagation conditions created by the less stable ionospheric conditions of the Arctic; (c) HF communications blackouts or polar cap absorption (PCA) sometimes lasting up to 10 days; (d) Delays sometimes in handling telegraphic traffic caused by the high density of traffic handled by coast stations awaiting clearance south; (e) Inability of ships and shore stations sometimes to reestablish contact, due to the above conditions, when initial contact is lost.
