Utqiaġvik (formerly Barrow)
In an area known as the “top of the world,” the NSA central facility at Utqiaġvik has hosted research near the coast of the Arctic Ocean since 1997. Smaller instrumented sites called extended facilities are located near the central facility.

Inactive ARM Sites in Alaska
Atqasuk: The Atqasuk facility, which was part of the larger NSA observatory, was installed in the summer of 1999 off of a road near the Atqasuk Airport and operated through 2010. Located approximately 70 miles south of Utqiaġvik, Atqasuk is adjacent to the Meade River. Its climate is much more continental than that of Utqiaġvik.
Oliktok Point: From 2013 to 2021, the third ARM Mobile Facility (AMF3) operated at Oliktok Point, about 160 miles east of Utqiaġvik. This remote deployment provided important data about arctic climate processes at the intersection of land and sea ice. The site also included DOE-controlled airspaces for crewed aircraft and uncrewed aerial systems.
Please note: Data from Oliktok and Atqasuk—as with all previous ARM deployments—remain freely available in the ARM Data Center.
