Iceberg concentrations and size distributions are monitored worldwide by the U.S. National Ice Center (NIC), established in 1995, which produces analyses and forecasts of Arctic, Antarctic, Great Lakes and Chesapeake Bay ice conditions. More than 95% of the data used in its sea ice analyses are derived from the remote sensors on polar-orbiting satellites that survey these remote regions of the Earth. thumb|Iceberg A22A in the South Atlantic Ocean The NIC is the only organization that names and tracks all Antarctic Icebergs. It assigns each iceberg larger than along at least one axis a name composed of a letter indicating its point of origin and a running number. The letters used are as follows: A – longitude 0° to 90° W (Bellingshausen Sea, Weddell Sea) B – longitude 90° W to 180° (Amundsen Sea, Eastern Ross Sea) C – longitude 90° E to 180° (Western Ross Sea, Wilkes Land) D – longitude 0° to 90° E (Amery Ice Shelf, Eastern Weddell Sea) The Danish Meteorological Institute monitors iceberg populations around Greenland using data collected by the synthetic aperture radar (SAR) on the Sentinel-1 satellites.
