International Ice Patrol - 1948. This is the "summing up". The chart pictured here shows the position of icebergs (small black triangles) and records their drift. From information submitted by survey lanes and shapes assigned to ice patrol, the chart is kept current. It is from this chart-summary that vital "ice-broadcasts" are made twice each day to all shipping on the Great Circle route to European ports. Combined air and surface operations and the effective use of radar and loran by Coast Guard patrol units contributed to the success of the 1948 International Ice Patrol. It was the mission
International Ice Patrol - 1948. This is the "summing up". The chart pictured here shows the position of icebergs (small black triangles) and records their drift. From information submitted by survey lanes and shapes assigned to ice patrol, the chart is kept current. It is from this chart-summary that vital "ice-broadcasts" are made twice each day to all shipping on the Great Circle route to European ports. Combined air and surface operations and the effective use of radar and loran by Coast Guard patrol units contributed to the success of the 1948 International Ice Patrol. It was the mission of the 1948 patrol to locate and report ice conditions constituting a menace to navigation, to determine set and drift of icebergs, to collect weather information and surface and sub-surface oceanographic data, and to keep all interested parties and commercial shipping informed thereof. The importance to mariners of "ice broadcasts" is evidenced by the fact that practically all commercial radio transmission ceases during these broadcasts. The International Ice Patrol along the steamer lanes of the North Atlantic is conducted by the United States Coast Guard. Coast guard cutters and planes assigned to the patrol are based at Argentia, Newfoundland.
