AVA-AK: North Slope ARCSS/LAII Flux Study (Walker 1995-1996 unpublished data)
Arctic Vegetation Archive - Alaska: North Slope ARCSS/LAII Flux Study. The vegetation and soils at the North Slope Arctic System Science/Land-Atmosphere-Ice Interactions... -
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 Floristic Provinces Map
The Arctic has a relatively consistent core ofplant species that occur throughout the circumpolar region, but there is also considerable east to west variation in regional... -
Circumpolar Arctic Lake Cover Map
Lake cover strongly affects the reflectance of the land surface over large areas of the Arctic, and was useful for identifying extensive wetlands. Lake cover was based on the... -
Ecosystems of Northern Alaska (Jorgenson & Heiner 2003)
Map image, GIS data and publication pending - This map was funded by The Nature Conservancy to provide a seamless ecological context for analysis of the distribution of... -
CANADIAN TRANSECT FOR THE CIRCUMPOLAR ARCTIC VEGETATION MAP (1999)
Variations in vegetation cover and species composition related to climate are evident from the southern to northern Arctic. Scientists involved in the Circumpolar Arctic... -
Circumpolar Arctic Biomass Trend 1982-2010 (Epstein et al. 2012)
Trend in Arctic biomass was calculated from a linear regression of biomass values for all years 1982-2010 (Epstein et al 2012). Pixels with significant trends (p < 0.05) were... -
Circumpolar Arctic AVHRR Summer Warmth Index 1982-2003 (Raynolds et al. 2008)
This data set was calculated from monthly AVHRR thermal infrared data (Comiso 2003). Summer Warmth Index (SWI) is the sum of monthly mean temperatures above 0 degrees Celsius.... -
Circumpolar Arctic Biomass (Raynolds et al 2012)
This map portrays an estimate of above ground plant biomass for the tundra biome based on trans-Arctic field data and AVHRR NDVI (Raynolds et al. 2012). Aboveground phytomass... -
Circumpolar Arctic Floristic Provinces Map
Floristic sectors characterize the considerable east-west floristic variation within the subzones. The more northern Arctic bioclimate subzones have a relatively consistent core... -
Alaska Arctic Lake Cover Map
Lake cover strongly affects the reflectance of the land surface over large areas of Alaska, and was useful for identifying extensive wetlands. Lake cover was based on the number... -
AVA-AK: ATLAS-2 (Raynolds et al. 2002)
Arctic Vegetation Archive - Alaska: ATLAS-2. The ATLAS-2 dataset is part of larger NSF-funded Arctic Transition in Land-Atmosphere System (ATLAS) project. ATLAS-2 contains the... -

AVA-AK: Frost Boil Vegetation Plots (Kade et al. 2005)
Arctic Vegetation Archive - Alaska: Frost Boil Vegetation Plots. The vegetation associated with cryoturbated frost-heave features on the North Slope, Alaska was described by... -
Circumpolar Arctic AVHRR NDVI Trend 1982-2008 (Bhatt et al. 2010)
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...
