U.S.C.G. International Ice Patrol
U. S. Coast Guard Drifting Buoys


The United States Coast Guard International Ice Patrol (IIP) is the oldest continuous user of the Argos Data Collection and location System.

During the iceberg season in the western North Atlantic Ocean, IIP deploys and tracks 12-16 freely drifting buoys. These drifters provide ocean current and sea surface temperature data for IIP's operational iceberg drift and deterioration models.

IIP uses a combination of aerial and satellite reconnaissance along with computer models to determine the extent of the iceberg danger area in the North Atlantic Ocean from February through July each year. IIP warns mariners of the location of the icebergs with a daily graphical or text-based product.

IIP was established under international agreement shortly after the sinking of the RMS TITANIC. The International Ice Patrol is a unit of the United States Coast Guard, the organization charged with conducting the North Atlantic Ice patrol (NAIP) service by the United States Government. The U.S. Government is the managing nation of NAIP under the auspices of the Safety of Life at sea (SOLAS) agreement.
