The Global Digital Sea Ice Data Bank (GDSIDB)
This project, the GDSIDB, initiated in 1989 in support of global climate monitoring, research and prediction, as well as specialized services, has as its primary objective to implement a consolidated data bank of digital sea-ice information. Several countries are participating, and contribute to the merging of digitized sea-ice data into a single data bank. The two main centres are the National Snow and Ice Data Center (NSIDC) in Boulder, USA and the Arctic and Antarctic Research Institute (AARI) in St Petersburg, Russian Federation. Comprehensive data sets now exist for the Arctic Ocean and other northern hemisphere sea ice areas, for the period from the 1960s to the present. Some digital data for the Antarctic are also available.
