Description:

Abstract:

These are geospatial data that characterize the distribution of polar bear denning habitat on the coastal plain of northern Alaska between the Colville River and the Alaska/Canada border. One dataset is included in this data package, it is vector geospatial data of putative denning habitat. The vector data are provided in both ESRI shapefile and Keyhole Markup Language (KML) formats. Den habitat is defined as abrupt landscape features (e.g., coastal and riverbanks, lake shores) that are likely to accumulate snow to a depth sufficient for polar bears to build a maternal den (i.e., > 1 meter deep).

Purpose:

These data were generated to provide vector geospatial data of putative denning habitat for polar bears on the Arctic coastal plain of Alaska.

Supplemental_Information:

This dataset is part of a USGS data release that includes three vector geospatial datasets of putative polar bear denning habitat from: (1) National Petroleum Reserve - Alaska (NPR-A), (2) the 1002 Area of the Arctic National Wildlife Refuge, and (3) the eastern Arctic Coastal Plain of Alaska between the Colville River and the Alaska/Canada border. Each dataset was derived at different times, with different objectives, and different techniques (documented in the respective metadata records). They have been available separately from the U.S. Geological Survey Alaska Science Center. They are collected here for distribution in a single data release.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Colville River (151° W) to the Tamayariak River (145° 30' W): 88% of bank habitat was identified correctly. Mapped habitat agrees closely with the distribution of actual polar bear dens. Of 15 known dens that were located inside the area of aerial photographs, 12 dens (80%) were within 135 m of mapped den habitat (Durner et al 2001).

Canning River (146° W) to the Canadian border (141° W): 91.5% of bank denning habitats on the ANWR coastal plain were correctly identified. Thirty-two of 38 known dens were within 145 m of mapped den habitat (Durner et al 2006).

Methodology_Description:

Colville River (151° W) to the Tamayariak River (145° 30' W): In addition to the standard-resolution photos described above, we examined 3000 aerial photographs (scale: 2.56 cm = 457.2 m [1 inch = 1500 feet]) taken along east/west transects over Alaskan coastal areas from the Colville River east to the Tamayariak River. The photos, provided by BP Exploration - Alaska, were taken as a part of standard exploratory procedures. Coverage included the area from the coastline to a mean 29 km inland (range 6.5-50.7 km; total area: 6335 km2). Photos were taken between 1981 and 1995 by twin-engine turbocharged aircraft (Cessna 320, Cessna 310, or Piper Aztec) flown at 2743 m (9000 feet) above mean terrain with a certified cartographic camera (15.4 cm [6 inch] focal length). Photo interpretation was done with a pocket stereoscope. Vegetation patterns also helped to identify topographic relief. We did not map sand dunes or pingos because their orientation and exposure to prevailing winds generally preclude sufficient snow accumulation. As well, anthropogenic landscape features were not mapped. Suspected banks of the dimensions required for denning were located and drawn on aerial photos as lines or arcs. Arcs were transferred into Interactive Graphics Design Software (IGDS) MicroStation (ver. 5, Intergraph Corp., Huntsville, Alabama) digital files by a CAD operator, either through direct digitization of photos, or by placement of lines along well-defined map features, such as shorelines or mapped bluffs. The final digital map of suspected den habitat was converted to ARC/INFO format (ver. 7.0.2, ESRI, Inc., Redlands, California). Additional details available in Durner et al. 2001.

Methodology_Type: Lab
Methodology_Description:

Canning River (146° W) east to the Canadian border (141° W): We examined 1655 high-resolution color aerial photographs (scale: 1 cm = 178.6 m) for den habitat. Photos were taken in 1981 with a certified cartographic camera (15.4 cm focal length), along east/west transects between the Canning River and the Canadian border, from a twin-engine turbocharged aircraft (Cessna 320, Cessna 310, or Piper Aztec) flown at 2743 m above mean terrain level. All photos were provided by the U.S. Fish and Wildlife Service. Den habitat was located on the photos with a pocket stereoscope and by interpretation of vegetation patterns. Linear features that showed elevation changes of 1 m or more were annotated on photos. Human-made landscape features, as well as sand dunes and pingos, were not mapped. Once identified on photos, den habitat was digitized and transferred to 1:63 360 base maps as line features through computer-aided drafting. The final format was provided as ARCVIEW shapefiles (ESRI, Redlands, California). Additional details available in Durner et al. 2006.

Process_Step:

Process_Description:

We examined photos that included known den sites we had visited, to confirm that features recorded at den sites could be identified from the photos. Next, we identified similar features across the study area by examining all photos. Photo interpretation was done with a pocket stereoscope. Vegetation patterns also helped to identify topographic relief. We did not map sand dunes or pingos because their orientation and exposure to prevailing winds generally preclude sufficient snow accumulation. As well, anthropogenic landscape features were not mapped. Suspected banks of the dimensions required for denning were located and drawn on aerial photos as lines or arcs. Arcs were transferred into Interactive Graphics Design Software (IGDS) MicroStation (ver. 5, Intergraph Corp., Huntsville, Alabama) digital files by a CAD operator, either through direct digitization of photos, or by placement of lines along well-defined map features, such as shorelines or mapped bluffs. The final digital map of suspected den habitat was converted to ARC/INFO format (ver. 7.0.2, ESRI, Inc., Redlands, California). Additional details about methods used are described in Durner et al. 2001 and Durner et al. 2006).
