The Anaktuvuk River Fire was the largest, highest-severity wildfire recorded on Alaska’s North Slope since records began in 1956. The 2007 Anaktuvuk River Fire was an order of magnitude larger than the average fire size in the historic record for northern Alaska and indices of severity were substantially higher than for other recorded tundra burns. An interdisciplinary team assessed fire effects including burn severity, potential plant community shifts, and effects on permafrost and active layers. Observers monumented, photographed, and measured 24 burned and 17 unburned reference transects, starting the year after the fire, and spanning the range of vegetation types and burn severities.

The purpose of this project is to provide better information to industry and regulatory agencies regarding the likely locations of polar bear dens. This project integrates snow physics, high-resolution digital elevation data, and bear biology to produce more refined and accurate maps predicting suitable polar bear den habitat than are currently available. The work consists of data gathering, consultation between snow and bear scientists, modeling, and sensitivity studies to understand the various factors influencing den location and evolution along the Beaufort Coast.The proposed work is intended to refine current methods of identifying polar bear denning sites by incorporating higher-resolution topographic data...
The Wildlife Conservation Society will assess the climate change vulnerability of bird species that regularly breed in substantial populations in Alaska using the NatureServe Climate Change Vulnerability Index (CCVI) tool. Initial work will focus on breeding birds in Arctic Alaska including shorebirds, waterfowl and waterbird species (loons, gulls, terns, jaegers), and land bird species (passerines, raptors, ptarmigan).

The Database was built to enable data integration across sources, as well as to support program planning and observational network design. The Imiq Data Portal provides a snapshot of available hydroclimate data – a map-based view of where , what , and when data have been obtained. Users can submit a custom data query, specifying variable of interest, geographic bounds, and time step. Imiq will aggregate and export data records from multiple sources in a common format, with full metadata records that provide information about the source data.

Arctic grayling (Thymallus arcticus) have a life-history strategy specifically adapted to the extreme climate of the North. These fish migrate to spawning grounds just after breakup in the spring, then migrate to feeding sites in early summer, and finally in the fall migrate back to their overwintering sites. The Kuparuk River is a perennial stream originating in the northern foothills of the Brooks Range on the North Slope of Alaska. Sections of the Kuparuk are periodically intermittent in that, during low flows in the system, these channel reaches appear dry. The flow varies between surface and subsurface in this permafrost-dominated environment, with subsurface flow being limited to the unfrozen thaw bulb around...

The Arctic Tern completes annual epic migrations from pole to pole covering at least 40,000 kmon their round-trip journeys. They breed throughout Arctic Alaska from boreal to tundra habitatsand have their highest nesting densities inland (Lensink 1984). Arctic Terns typically choose nestsites on open ground near water and often on small islands in ponds and lakes (Hatch 2002).Arctic terns consume a wide variety of fish and invertebrate prey, fish are particularly importantduring the breeding season for feeding young (Hatch 2002). This species spends their winters(austral summers) in offshore waters near Antarctica (Hatch 2002). Alaskan Arctic Coastal Plainpopulation estimates from 2011 range from 7-12,000 (Larned...
The Pectoral Sandpiper is one of the most abundant breeding birds on the Arctic Coastal Plain ofAlaska. They typically have low nest site fidelity which is likely related to their promiscuousmating strategy, thus nest densities are highly variable from year to year at a given site (Holmesand Pitelka 1998). In Arctic Alaska, primary breeding habitat includes low-lying ponds in a mixof marshy to hummocky tundra and nests are typically placed in slightly raised or better drainedsites (Holmes and Pitelka 1998). Pectoral Sandpipers spend their winters primarily in southernSouth America (Holmes and Pitelka 1998). The current North American population estimate is500,000 and they are believed to be declining (Morrison et...
Water availability, distribution, quality and quantity are critical habitat elements for fish and other water-dependent species. Furthermore, the availability of water is also a pre-requisite for a number of human activities. The density of weather and hydrology observation sites on the North Slope is orders of magnitude less than in other parts of the U.S., making it difficult to document hydrologic trends and develop accurate predictive models where water is a key input. The information that does exist is scattered among many entities, and varies in format. This multi-year data rescue effort project brings together these scarce and scattered hydrology data sets, including high-priority datasets held by the Bureau...

The Geographic Information Network for Alaska will complete uniform and consistent ecological mapping of the North Slope region and provide a summary of existing field site ecological descriptions (including photos) in a web based environment. Existing automated field information and photos that have reliable geolocation information will be compiled and entered in a web based geographic display based on the ecological mapping.
These raster datasets represent historical stand age. The last four digits of the file name specifies the year represented by the raster. For example a file named Age_years_historical_1990.tif represents the year 1990. Cell values represent the age of vegetation in years since last fire, with zero (0) indicating burned area in that year. Files from years 1860-2006 use a variety of historical datasets for Boreal ALFRESCO model spin up and calibration to most closely match historical wildfire dynamics.

Watersheds draining the Arctic Coastal Plain (ACP) of Alaska are dominated by permafrostand snowmelt runoff that create abundant surface storage in the form of lakes, wetlands, and beaded streams. These surface water elements compose complex drainage networks that affect aquatic ecosystem connectivity and hydrologic behavior. The 4676 km2 Fishand Creek drainage basin is composed of three watersheds that represent a gradient of theACP landscape with varying extents of eolian, lacustrine, and fluvial landforms. In each watershed, we analyzed 2.5-m-resolution aerial photography, a 5-m digital elevationmodel, and river gauging and climate records to better understand ACP watershed structureand processes. We show that...

The Integrated Ecosystem Model is designed to help resource managers understand the nature and expected rate of landscape change. Maps and other products generated by the IEM will illustrate how arctic and boreal landscapes are expected to alter due to climate-driven changes to vegetation, disturbance, hydrology, and permafrost. The products will also provide resource managers with an understanding of the uncertainty in the expected outcomes.
More than 35,000 lakes larger than 0.01 sq. km. were extracted from an airborne interferometric synthetic aperture radar (IfSAR) derived digital surface model acquired between 2002 and 2006 for the Western Arctic Coastal Plain of northern Alaska. The IfSAR derived lake data layer provides an improvement over previously available datasets for the study area since it is more comprehensive and contemporary. Attributes assigned to the IfSAR-derived lake dataset include: area, lake elevation, elevation in 10, 25, 50, and 100 m buffers around a lake perimeter, the difference in elevation between the lake and these various buffers, whether a particular lake had a detectable drainage gradient exceeding 1.2 m, whether a...
