The Ivotuk study site is located in northwestern Alaska, on the North Slope of the Brooks Mountains Range. The study site was chosen because four tundra vegetation types, moist acidic tundra (MAT), moist nonacidic tundra (MNT), mossy tussock tundra, and shrub tundra exist within a 2 km2 area. This project was funded by the NSF Arctic System Sciences, Land-Atmosphere-Ice Interactions Program (OPP-9908829) as part of the Arctic Transitions in the Land- Atmosphere System (ATLAS) effort.
The four 100 x 100 m grids were mapped as raster maps, using aerial photographs and ground verification. Both vegetation types (22 units) and microsites (13 units) were mapped on the grids.
The GIS data and raster maps will be uploaded when they become available.
