The Circumpolar Active-Layer Permafrost System (CAPS) CD-ROM contains data sets and information products pertaining to permafrost and frozen ground topics. CAPS was originally compiled by the International Permafrost Association's (IPA) Standing Committee on Data Information and Communication (SCDIC) in 1998, and was updated by NSIDC and the IPA's SCDIC in 2003. CAPS contains over 100 data sets ... and information products pertaining to permafrost and frozen ground topics. It also contains detailed metadata records describing over 100 additional data sets available at other GGD nodes around the world. Dozens of contributors submitted data collections representing global sites. This compilation of data and information products is intended for a broad audience including the scientific and engineering communities, educators, and policy makers. The data published on CAPS is now only available through the Frozen Ground Data Center (FGDC) Web site. The CAPS is no longer available through CD-ROM.
