Landsat TM and ETM data were used to calculate NDVI for the study area (823 km^2). This image shows the results of a slope of linear regression of NDVI for 1985, 1989, 1995,...

This vector (shp) map is a simplified version (1:25000) of Thomas Hamilton's glacial geology map of the Upper Kuparuk River region (Hamilton 2003), which provides detailed...

The vegetation of the Upper Kuparuk River Region was studied and mapped as part of the Arctic Long-Term Ecological Research (LTER) project at Toolik Lake and the Department of...

The Toolik Lake Grid map focuses on the south side of Toolik Lake. This area is one of the principal intensive research areas at the Toolik Lake Field Station. It includes many...

Map of the Toolik Lake research area surficial geomorphology . The Toolik Lake area map is near the western boundary of the Upper Kuparuk River region map and encloses a 20-km^2...

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....

Map of the Toolik Lake research area percent water. The amount of water (lakes, ponds, streams, wetlands), strongly affects the reflectance of the land surface over large areas...

The map encloses a 20 km^2 area surrounding Toolik Lake that stretches from the Dalton Highway on the east to Jade Mountain on the west. It includes the Toolik Field Station,...

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...

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...

The Deadhorse patterned-ground grid is located near the industrial center of Deadhorse, AK, within 15 km of the Beaufort Sea coast. There is one 10 x 10 m grid, with a complex...

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....

This mapping includes six locations along the Dalton Highway and in the Prudhoe Bay Oilfield area, forming a north-south transect across the climate gradient on the North Slope...

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...

In 1976, the Northwest Alaska Native Association (NANA) and the Reindeer Herders Association (RHA) asked the Alaska Soil and Water Conservation District and the United States...

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...

The Happy Valley patterned-ground grids are located in Subzone E, the warmest part of the Arctic, in the foothills of the Brooks Range, just west of the Sagavanirktok River and...

In spring of 2002, the National Science Foundation Arctic Logistics and Research Support Program funded the acquisition and distribution of a new Digital Elevation Model (DEM)...

This map was created for the US National Science Foundation Land-Atmosphere-Ice Interactions (LAII) Flux Study and the Arctic Transitions in the Land-Atmosphere System (ATLAS)...

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...
