[en] The Arctic Environmental Data Directory (AEDD) is being developed in cooperation with the US Global Change Research Plan. The AEDD Working Group, with members from US and Canadian agencies and academia, have described more than 300 Arctic data sets in a subset of an online data directory maintained by the US Geological Survey (USGS), ESDD (the Earth Science Data Directory). Through various links known as the Inter-operable Directory, the contents of AEDD are made available to scientists who use the NASA, NOAA, NSF and USGS data directories. Thus, scientists studying global change have access to Arctic data, and scientists studying the Arctic have access to global change data. The AEDD Working Group has sponsored development of a prototype Compact Disc Read Only Memory (CDROM) containing the indexed contents of the AEDD. Named Arctic Data Interactive (ADI), the disc was developed for use on Apple Macintosh and IBM PC-compatible computers, and uses a graphical and intuitive hypermedia user interface. The disc also contains portions of an Arctic Bibliography prepared in concert with the Polar Library Colloquy, sample full-text articles with illustrations, and selected data sets, including tabular data, text, and imagery. The ADI prototype is prepared as a model for organizing, presenting and distributing large quantities of Arctic and global change data and information to the science community. It is intended to be the first series of CDROMs with a consistent graphic design and user interface to place Arctic data and information on the desktop. The data are packaged with a powerful set of intuitive tools to navigate through and preview data sets from many disciplines and institutions. AEDD and ADI are sponsored by the Inter-agency Arctic Research Policy Committee and the Inter-agency Working Group on Data Management for Global Change, with guidance from the US Arctic Research Commission
