Canada: 

The Polar Continental Shelf Project (PCSP) maintains two base camps in the Canadian Arctic, Resolute and Tuktoyaktuk. PCSP supports approximately 200 scientific projects each year through these camps, including accommodations, equipment loans, establishment of remote field camps, air transport through long-term chartering, and a radio communications system that maintains contact with remote field camps and aircraft. U.S. scientists can use PCSP facilities and services on a space-available basis for nominal fees.

Greenland: 

The U.S. currently supports, or U.S. researchers can access, logistical capabilities for research at Thule, Kangerlussuaq, Summit, and Zackenberg. The U.S. presence in Greenland is supported through an international agreement with Denmark. The logistical support system is based on open access to and use of a combination of Danish government-sponsored research programs, Danish and Greenlandic governmental and civilian transportation system infrastructure, the U.S. Department of Defense presence at Thule Air Base, the U.S. Air National Guard LC-130 air support capability, and U.S. federal agencies investments in research facilities and support services at coastal and ice sheet locations. For a thorough online guide to planning research in Greenland, see the "Project Planner" on the website of the Danish Polar Center.

Fennoscandia:       

The research stations in the Fennoscandian countries are supported directly by their governments and are of high quality and capability. Excellent research facilities exist on Svalbard near Longyear-byen and at Ny-Ålesund, a year-round international arctic environmental research and monitoring station in a more remote area (at 79°N) that can accommodate up to 150 persons. On the Norwegian mainland, the University of Tromsø has extensive research facilities and a medical school. The NSF OPP has recently signed a Statement of Cooperation with the Norsk Polarinstitutt to promote increased interactions among U.S. and Norwegian scientists in arctic and antarctic research efforts. In arctic Sweden, Abisko Scientific Research Station is a year-round research facility that can house up to 80 workers.The Kevo Subarctic Research Institute and Kilpisjärvi Biological Station in arctic Finland are both year-round facilities, and each can accommodate around 40 researchers.

Russia: 

Much of the vast Russian Arctic is inhabited, and large parts of the region potentially can be reached by commercial air and rail systems. In addition, several research stations and sites with a rich heritage of environmental research and observations exist in the Russian tundra regions. For example, the year-round Northeast Science Station at Cherskii in Sakha can accommodate 15 to 20 people and affords access to an experimental wildlife preserve. Due to the recent transitions in Russia, accurate information on the status of and access to other research facilities can be difficult to obtain. In response to these and other practical obstacles, NSF has recently announced establishment of a science liaison office in Moscow to assist U.S. arctic researchers interested in conducting field work in the Russian Arctic.

United States: 

The U.S. Arctic (northern Alaska) has two research facilities that include laboratory space and tracts of land reserved for research use and that act as logistics hubs for adjacent areas: Barrow on the Arctic Coast andToolik Field Station (TFS) in the northern foothills of the Brooks Range. . The TFS, established in 1975, is accessible from the Dalton Highway and has had a steadily growing user base. TFS currently supports over 3,000 user days each year. While facilities at TFS are still marginally adequate for current use, facilities upgrades funded by NSF since 1994 have improved laboratory facilities and now allow winter use of the station.
