Arctic Definitions

Arctic Definitions

Under this section, a selection of maps representing the main definitions of “Arctic” is presented.

Maps can be combined among them or with maps presented under other sections (as for instance Arctic Summer Sea Ice extent and “Arctic definitions”). All maps can be purchased and downloaded in high resolution. Maps can be snipped or copied for use in presentations as long as its origin is clearly accounted for.

For further information, such as inquiries on maps with even higher resolutions or with different dataset combinations, please contact info at arcticportal.org.
