The project utilized data from the Waterfowl Breeding Population and Habitat Survey, which is an annual survey conducted since 1955 by the governments of the United States and Canada to monitor waterfowl populations. These survey data were spatially and temporally layered onto long-term databases of fire perimeters for Alaska and western Canada, providing a record of waterfowl transects which had burned over the last 60 years. The project modelled abundance of dabbler and diver pairs in relation to time since fire, looking at short-term (e.g., 1–3 years) versus long-term timeframes (e.g., >5 years), and in relation to fire extent, defined as the percent of transect which had burned.

This package contains seven tables of avian and habitat survey data from Bering Land Bridge National Preserve; part of the Arctic National Park Network (ARCN), Alaska. Tables include: 1) characteristics of bird survey sites, 2) vegetation classification at survey sites, 3) shorebird and predator detection surveys, 4) spot check bird surveys, 5) all bird species detection surveys, 6) taxonomic details of observed birds, and 7) point count habitat photos. Additionally, geospatial data corresponding to subsections, survey plots, and points are included with this data release in folder "montaneBirdInventory_geospatial_BELA". All data pertaining to the Bering Land Bridge National Preserve is also released as part of a study on Bristle-thighed Curlew abundance and habitat use on the Seward Peninsula. Note: The data presented in this release were collected following an unpublished protocol (C. Handel et al. unpubl., USGS ASC, Anchorage, AK).

This data package presents raw legacy data collected during 1974-1992 on the Arctic Coastal Plain (primarily in the National Petroleum Reserve - Alaska; NPR-A). The data were collected in support of a long-term multi-species wetland ecosystem study that aimed to provide an understanding of occurrence and densities of bird, mammal, fish, invertebrate, and plant species. The study included the Teshekpuk Lake Special Area (TLSA), as well as focused studies on individual lakes or regions within the special area, including: East Long Lake, West Long Lake, Goose Lake, Island Lake, Square Lake, Meade River (Singiluk), Point Storkersen, and Icy Cape. The study included 10 primary objectives: 1) complete daily weather records, 2) chart avian phenology, 3) census large and small bird species, 4) map bird nests and record success, 5) record caribou movements, 6) sample wetlands for aquatic macroinvertebrates, 7) establish a small mammal trapline, 8) observe activity and feeding habits of molting geese, 9) map vegetation trend plots for ground truth, and 10) record fox observations and den sites. Not all objectives were completed in all years and at all locations. The data are provided as digital scans (PDF format for documents and JPG format for photographs) of original field data sheets, notebooks, tables, figures, maps, and photographs (scanned film and slides). All data are organized in folders by topic and study site location. Since the data are in original form and were not digitized at the time of data collection, the data have not undergone formal Quality Assurance/Control Quality (QA/QC). Additional documentation of project field methods are limited for most years and locations of study, however, reports summarizing data collected at several locations are listed in the Cross Reference section. These are scanned originals and replications and some text may be illegible.

This data set contains annual modeled estimates of wildland fire emissions at 0.01 degree (~1-km) spatial resolution from the Wildland Fire Emissions Information System (WFEIS v0.5) for the conterminous U.S. (CONUS) and Alaska for 2001 through 2013. WFEIS is a web-based tool that provides resources to quantify emissions from past fires and output results as spatial data files (French et al., 2014). The data set includes emissions estimates of carbon (C), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), other non-methane hydrocarbons (NMHC), and particulate matter (PM) as well as estimates of above-ground biomass, total fuel availability, and consumption estimates.

This dataset represents percent area burned in each burn severity class for wildfires within individual local and accumulated upstream catchments for NHDPlusV2 Waterbodies for each year for 1984-2018.The Monitoring Trends in Burn Severity MTBS project assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (includes wildfire, wildland fire use, and prescribed fire) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico from the beginning of the Landsat Thematic Mapper archive to the present.

This dataset provides annual cumulative end-of-season burned area in circumpolar boreal forests and tundra for the years 2002-2022. The data were generated using the Arctic Boreal Burned Area (ABBA) version 2 algorithm with MODIS collection 6 products. The algorithm is based on Normalized Burned Ratio differencing (dNBR) and is designed specifically to capture late season fires. The annual MODIS Vegetation Continuous Fields (VCF) 250-m Collection 5.1 (MOD44B) product allowed for additional vegetation-dependent dNBR thresholds within the algorithm's processing steps. The spatial domain is circumpolar regions above 50 degrees north latitude. The data are provided in cloud-optimized GeoTIFF format with 463-m resolution.
