Circumpolar Landscape Age Map (Raynolds et al. 2008)
The landscape age map shows the length of time (in thousands of years) that Arctic landscapes have been available for plant colonization and the development of plant communities... -
Circumpolar Arctic Elevation Map
Elevation strongly influences soil moisture and patterns of tundra plant communities. Areas less than 100 m above sea level were separated to show low-elevation plains. Areas... -
Circumpolar Arctic Bioclimate Subzones
A fundamental problem for the CAVM is how to characterize the transitions in vegetation that occur across the roughly 10 °C mean July temperature gradient from the tree line to... -
Alaska Arctic Elevation Map
Elevation strongly influences soil moisture and patterns of tundra plant communities. Areas less than 100 m above sea level were separated to show low-elevation plains. Areas... -
Alaska Arctic Vegetation Map
Mapped polygons at 1:7.5 million scale contain many vegetation types. The map portrays the zonal vegetation within each mapped polygon. Zonal sites are areas where the... -

Sagwon Patterned-Ground 10 x 10 m Grids
The Sagwon patterned-ground grids are located at the northern edge of the rolling foothills, at the boundary with the flatter coastal plain. This is also the boundary between... -
Beechey Point Land Cover Classification: CRREL Report 87-5
This report presents a Landsat-derived land cover classification of the Beechey Point, Alaska, 1:250,000-scale quadrangle with descriptions of the major vegetation units. Eight... -
Landsat MSS-derived land-cover map of the Seward Peninsula, Alaska
This land cover map of the Seward Peninsula is based on a classification of Multi-Spectral Scanner (MSS) data. The Landsat multiple scene mosaic was furnished by the USGS, EROS... -
Upper Kuparuk River Region Surficial Geology
Surficial geology affects vegetation patterns and disturbance recovery rates. Surficial geology was grouped into the following classes for map display: • Glacial till deposit:... -
Alaska Arctic AVHRR NDVI Map
The normalized difference vegetation index (NDVI) is a measure of greenness. NDVI was calculated as: NDVI = (NIR - R) / (NIR + R), where NIR is the spectral reflectance in the... -
AVA-AK: North Slope ARCSS/LAII Flux Study (Walker 1995-1996 unpublished data)

Franklin Bluffs Patterned-Ground 10 x 10 m Grids
The Franklin Bluffs patterned-ground grids are located in Subzone D, on the coastal plain of the Alaska North Slope, just west of the Sagavanirktok River. There are three 10 x... -
Alaska Arctic Bioclimate Subzone Map
Various authors, working with different geobotanical traditions, have divided the Arctic into bioclimatic regions using a variety of terminologies. The origins of these... -
Circumpolar Arctic Landscape Map
The landscape map was derived from topographic data, regional physiographic maps, and visual interpretation of the AVHRR false-CIR image. Landscape codes were assigned to each... -
