• The Toolik Field Station (TFS) is operated and managed by the Institute of Arctic Biology of the University of Alaska Fairbanks (UAF) with cooperative agreement support from the Division of Arctic Sciences of the Office of Polar Programs at the National Science Foundation (NSF).
• TFS provides housing, meals, and laboratories in addition to support services for arctic research and education to scientists and students from universities, institutions, and agencies from throughout the US and the world. Research support includes GIS and mapping services, technical and IT assistance, shared commonly used equipment, and collection of standardized environmental data.

• A user-day fee contributes to costs of operations, and a Steering Committee and science user input advises TFS management on the direction and extent of science support and station operations.
• Through NSF’s Arctic Research Support and Logistics contractor, CH2MHill Polar Services (CPS), TFS is also provided with research helicopter support and its infrastructure is developed and maintained. TFS infrastructure and equipment are owned by either UAF or NSF.
