This collection of files contains temperature data files (.ttd files) downloaded directly from Tiny Tag devices, as well exported temperature data as .csv files for each nest monitored with Tiny Tags by year. File names include Tiny Tag number, site, year, and nest ID..ttd files can be viewed using Tinytag Explorer. Note, however, that the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. All .csv files were exported using the Tinytag Explorer during the same daylight savings...

The Gap Analysis Project (GAP) is an element of the U.S. Geological Survey. GAP helps to implement the Department of the Interior’s goals of inventory, monitoring, research, and information transfer. GAP has three primary goals: Identify conservation gaps that help keep common species common; Provide conservation information to the public so that informed resource management decisions can be made; and Facilitate the application of GAP data and analysis to specific resource management activities. To implement these goals, GAP carries out the following objectives: Map the land cover of the United States Map predicted distributions of vertebrate species for the U.S. Map the location, ownership and stewardship of...

This data release contains observation data, design transects, design strata, analysis estimates output, and associated metadata from the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey. The Alaska Arctic Coastal Plain Aerial Breeding Pair Survey provides data on distribution, abundance, and trend of 33 bird species that nest in northern Alaska. The survey has been conducted in its current form annually since 2007 with the exception of years 2020 and 2021. Methods generally follow the standard operating procedures for the Waterfowl Breeding Population and Habitat Survey. Primary uses of the survey data are to evaluate recovery status of Spectacled Eider (Somateria fischeri) and Steller’s Eider (Polysticta...

Collection of video files taken of avian nests by Plotwatcher Pro–Time Lapse cameras during field work conducted on the Arctic National Wildlife Refuge. Photos are organized in folders by year. Naming convention for each photo includes nest ID and camera number. Within each NestID folder are a series of TLV files saved directly from cameras. TLV files can be saved as an AVI file to view in Windows. Note, in 2019 camera date and times were not set correctly prior to deployment. See ‘ANWR nest survival nest data’ for date and time as set on the camera at time of deployment. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that...

This collection of files contains raw location data for shorebirds tagged with tracking devices and can be found in the raw data folder.Directories include: Argos_REPH, Argos_WHIM, GPS_PESA_AMGP_WHIM, and Pinpoint_SESA_DUNL.Argos_REPH: contains raw location data for Red Phalaropes equipped with 2-gram solar PTT tags manufactured by Microwave Telemetry, Inc in 2019 and 2020. Raw data files include annual PRV/A DS data files downloaded from the Argos website (http://argos-system.org) (.txt files) as well as data automatically downloaded by the Movebank website (www.movebank.org) (.csv file). Also included are data files (.kml and .txt files) obtained from processing the raw PRV/A DS data files with the Microwave MTI...

This collection of files contains independent assessments of both the Tiny tag and camera data, as well as temperature actograms produced by Martin Bulla in his assessment of the Tiny Tag data. Each assessment is saved as a separate file, containing the name of the reviewer in the file name. Note, that .ttd files viewed using Tinytag Explorer may have assessment times that are off by an hour, as the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. Also, in 2019 camera date and...

The U.S. Geological Survey (USGS), in partnership with several federal agencies, has now developed and released seven National Land Cover Database (NLCD) products: NLCD 1992, 2001, 2006, 2011, 2016, 2019, and 2021. Beginning with the 2016 release, land cover products were created for two-to-three-year intervals between 2001 and the most recent year. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. NLCD continues to provide innovative, consistent, and robust methodologies for production of a multi-temporal land cover and land cover change database. The NLCD 2021 release is update based, so the Land Cover and Impervious Surface products released in...

Collection of photographs taken during nest survival field work on the Arctic National Wildlife Refuge. Photos include those taken of nests and nest habitat at time of revisit (i.e., after nests hatched or failed), completed datasheets, by crew members, and select images from the Plotwatcher Pro–Time Lapse cameras. Directories include ANWR_nest_survival_nest_photos, ANWR_nest_survival_datasheet_photos, ANWR_nest_survival_other_photos, ANWR_nest_survival_plot_camera_photos. Note, in 2019 camera date and times were not set correctly prior to deployment. See ‘ANWR nest survival nest data’ for date and time as set on the camera at time of deployment.

This collection of files includes audio files downloaded directly from acoustic monitors in 2022, providing sound recordings of shorebird PRISM plots. Using automatic recorders allows for a consistent, unbiased, and regular data collection during the whole summer and will be used to verify PRISM survey data and determine if shorebirds can be monitored remotely using audiorecording devicies. Files are organized in folders by plot. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less...
