A wealth of data is collected and assessed by the Arctic Council. The Conservation of Arctic Flora and Fauna (CAFF) and the Protection of the Arctic Marine Environment (PAME) working groups have developed a site to house the information.
ArcticData is an ongoing project that provides data in an easily accessible and useable format.
Find downloadable data sets on Arctic boundaries, topography, protected areas, biodiversity, shipping, and linguistics on the ArcticData site. CAFF and PAME are constantly adding information and data sets to the site. Check back often.
