This study is developing a GIS at multiple scales for the Kuparuk River Basin and other sites in Alaska. The project includes geobotanical sampling of 1 x 1 km grids at 100 m intervals for vegetation, soils, and active layer depth. Sites are:

U1 Barrow Grid (71 deg 20 min N, 156 deg 30 min W)
U3 Atkasook Grid (70 deg. 27 min N, 157 deg 25 min W)
U5 West Dock Grid (70 deg 22 min N, 148 deg 34 min W)
U7 Betty Pingo Grid (70 deg 17 min N, 148 deg 52 min W)
U10 Happy Valley Grid (69 deg 9 min N, 148 deg 51 min W)
U11 Imnavait Creek Grid (68 deg 37 min N, 149 deg 18 min W)
U12 Toolik Lake Grid (68 deg 37 min N, 149 deg 36 min W)
R4 GIS also includes Parisento Grid (approx 70 deg N, 76
deg E).

These sites are part of the IPA Circumpolar Active Layer Monitoring (CALM) Program.
