Toolik Lake Grid Digital Elevation Map (DEM)
This Digital Elevation Map (DEM) was created from the contour lines of the Aerometrics orthophoto from 1996. In addition the 1 x1 km CALM grid with 121 points (every 100 m) was... -
Upper Kuparuk River Region
This map contains a group of vegetation maps at three scales in the vicinity of the Toolik Field Station, Alaska. The maps are intended to support research at the field station.... -
Geobotanical Atlas of the Prudhoe Bay Region (Walker et al. 1980)
This map covers most of the Prudhoe Bay Oilfield on the North Slope of Alaska that was under development in 1980, covering 145 km^2. The map synthesizes work done for the US... -
West Dock Patterned-Ground 10 x 10 m Grids
The West Dock biocomplexity grid is located near the water pumping facility at West Dock in the Prudhoe Bay oilfield, AK, within 1 km of the Beaufort Sea coast. There is one 10... -
Howe Island Patterned-Ground 10 x 10 m Grids
The Howe Island biocomplexity grid is located on a 1.5 x 0.5 km island off the delta of the Sagavanirktok River, west of the Endicott Causeway in the Prudhoe Bay oilfield, AK.... -
Prudhoe Bay Cumulative Impact Map A: Raynolds 2014
Map A of the historical infrastructure changes for the Prudhoe Bay Oilfield for 10 dates from the initial oil discovery in 1968–2011. Aerial photos taken in 1949 and 1968 were... -
Prudhoe Bay Cumulative Impact Map B: Raynolds 2014
Map B of the historical infrastructure changes for the Prudhoe Bay Oilfield for 10 dates from the initial oil discovery in 1968–2011. Aerial photos taken in 1949 and 1968 were... -
Kuparuk River Basin Hydrology Map
Hydrology of the Kuparuk River basin, including streams, rivers, ponds, lakes, and coastline. The map includes line features as well as polygon features (.shp). This map was... -
Circumpolar Arctic AVHRR False Color-Infrared (CIR) Map
Advanced Very High Resolution Radiometer (AVHRR) data were obtained from the USGS Global AVHRR 10-day composite data. (http://edcdaac.usgs.gov/1KM/1kmhomepage.asp) (Markon et... -
Prudhoe Bay Cumulative Impact Map C: Raynolds 2014
Map C of the historical infrastructure changes for the Prudhoe Bay Oilfield for 10 dates from the initial oil discovery in 1968–2011. Aerial photos taken in 1949 and 1968 were... -
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... -
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... -
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... -
Circumpolar Arctic Vegetation Map (CAVM Team 2003)
The Circumpolar Arctic Vegetation Map (CAVM) is a geoecological map of the entire Arctic with a unified legend. It is the first vegetation map of an entire global biome at a... -
Alaska Arctic Substrate Chemistry Map
Differences in substrate chemistry, including pH, govern the availability of essential plant nutrients. Soils in the circumneutral range (pH 5.5-7.2) are generally mineral rich,...
