The Norwegian Polar Institute (NPI) initiated an international programme for systematic collection of Antarctic iceberg data in 1981. The initiative was motivated by a lack of data on the spatial and temporal distribution of icebergs in Antarctic waters. The program was endorsed by the Scientific Committee on Antarctic Research (SCAR) through its Working Group on Glaciology, and quickly gained support from nearly all SCAR nations. The main part of the database contains a total of 323 520 iceberg positions from 26 634 individual observations. Of these, 262 007 icebergs have been classified by size into five different length categories: 10-50, 50-200, 200-500, 500-1000 and ˃1000 m. Additionally, the database contains 8061 AAD observations of altogether 53 649 icebergs, of which 38 756 were classified in somewhat different categories: 25-100, 100-200, 200-400, 400-800, 800-1600, 1600-3200 and ˃3200 m. These data are from the seasons 1984/85 to 2010/11.
