additional data delivery medium. The ARCSS data management effort is a
two-way street; we work with investigators to archive their data while making
these same data readily available for other investigators.
Data sets and products from AOS-94 will be listed in the on-line and hard-
copy versions of the ARCSS Data Catalog, as well as in the Global Change
Master Directory, the Arctic Environmental Data Directory and the Interna-
tional Arctic Environmental Data Directory. These on-line information ser-
vices provide a means of notifying the international science community of
these data sets, with up-to-date contact information to order the data. In ad-
dition, NSIDC maintains an ARCSS Web site (http://arcss.colorado.edu) that
will explicitly list AOS-94 data with ordering information and/or links to down-
load the data from within a Web browser. News of ARCSS data issues and
activities is available in the quarterly newsletter NSIDC Notes, obtainable by
free subscription and on the NSIDC Web site.
The AOS-94 data archiving plan will stipulate a period of exclusive use by
the investigators, perhaps two years from the end of the cruise, after which the
data should be moved into the archive and released for general distribution.
The time period of exclusive use has not yet been negotiated with the project
leaders or the individual investigators.
