International Ice Patrol Iceberg Drift Tracks, Version 1

The International Ice Patrol (IIP) tracks, plots, and predicts iceberg positions in the North Atlantic Ocean. The IIP area of responsibility is 40 to 52 degrees North, 39 to 57 degrees West. During several years (1977, 1978, 1980, 1983, and 1989) individual icebergs were tagged with buoys developed by the U.S. Coast Guard Research and Development Center. The motion of the icebergs bearing the USCG buoys were then tracked via satellite. Observation periods range from one week to two years depending on the buoy. The data are stored in the National Oceanographic Data Center format for drifting buoys (format number 156).

国际冰情巡逻队（International Ice Patrol, IIP）负责北大西洋海域冰山的追踪、标绘与位置预报。其责任海域范围为北纬40°至52°、西经39°至57°。在1977、1978、1980、1983及1989年这几个年份中，研究人员使用美国海岸警卫队研究与发展中心（U.S. Coast Guard Research and Development Center）研发的浮标对单座冰山进行标记。随后，搭载美国海岸警卫队（U.S. Coast Guard, USCG）浮标的冰山运动轨迹通过卫星完成追踪。根据浮标的型号差异，单次观测周期从1周至2年不等。所有数据以美国国家海洋资料中心（National Oceanographic Data Center）的漂移浮标数据格式（格式编号156）进行存储。
