The development of trans-oceanic aviation in the postwar years created a need for accurate weather information over the Atlantic and Pacific Oceans. An international agreement in 1946 established 13 Ocean Weather Stations with Canada being responsible for two, ocean station Baker several hundred miles off the east coast from 1947 to 1950 and for ocean station Papa off the coast of Vancouver from 1950 to 1981. A number of ships, both converted RCN vessels and purpose built CCG weather ships were stationed at these points to gather weather information during these years. Ships involved included, HMCS St. Stephen, HMCS St. Catherines, HMCS Stone Town, CCGS Vancouver, and CCGS Quadra.
