Information about ASPeCt data can be found on the ASPeCt website.

The Climate and Cryosphere (CliC) program focuses on all regions of the cryosphere including ice sheets, ice shelves, glaciers, river and lake ice, permafrost and frozen ground, snow-covered regions, and sea ice.

The International Antarctic Zone Program (iAnZone) focuses on the oceanography of the Southern Ocean, with particular emphasis on the sea ice zone. It has strong links to the goals and objectives of ASPeCt.
