At the first International Conference on the Safety of Life at Sea, which was convened in London on 12 November 1913, the subject of patrolling the ice regions was thoroughly discussed. The convention signed on 30 January 1914, by the representatives of the world's various maritime powers, provided for the inauguration of an international derelict-destruction, ice observation, and ice patrol service, consisting of vessels, which should patrol the ice regions during the season of iceberg danger and attempt to keep the trans-Atlantic lanes clear of derelicts during the remainder of the year. Due primarily to the experience gained in 1912 and 1913, the United States Government was invited to undertake the management of the triple service, the expense to be defrayed by the 13 nations interested in trans-Atlantic navigation.
