Report of the International Ice Patrol in the North Atlantic, 2012 Season, Bulletin No. 98.

摘要

This is the 98th annual report of the International Ice Patrol (IIP). IIP was under the operational control of Commander, U.S. Coast Guard First District. The report contains information on IIP operations, environmental conditions, and iceberg conditions in the North Atlantic during 2012. The Ice Patrol was formed after the RMS Titanic sank on 15 April 1912. Since 1913, except for periods of World War, Ice Patrol has monitored the iceberg danger near the Grand Banks of Newfoundland and has broadcast the Iceberg Limit to mariners. The activities and responsibilities of IIP are delineated in U.S. Code, Title 46, Section 80302 and the International Convention for the Safety of Life at Sea (SOLAS), 1974. IIP conducted aerial reconnaissance from St. Johns, Newfoundland to search for icebergs in the North Atlantic and Labrador Sea. In addition to IIP reconnaissance data, Ice Patrol received iceberg reports from other aircraft and mariners in the North Atlantic. At the Operations Center (OPCEN) in New London, Connecticut, personnel analyzed iceberg and environmental data and used the iceberg Analysis and Prediction System (BAPS) computer model to predict iceberg drift and deterioration. Based on the models prediction, IIP produced a daily ice chart and text bulletin in 2012 under the North American Ice Service Collaborative Arrangement. In addition to these routine broadcasts, IIP responded to individual requests for iceberg information.
