This contain a zip folder of comma delimited (CSV) files for each of the 19 tables in the report. It is produced automatically upon compiling the R Quarto code. Column headers are difference than in the tables in the report but order is exactly the same. Refer to the report to understand meaning of the columns. Each cell of the tables contain a management index estimate or the standard error of the estimate.

This project is an annual communicating memo explicitly designed to inform the Pacific Flyway Representative of waterfowl survey results for incorporation of the data into harvest management reports and regulatory processes. This memorandum is additionally shared widely with partners outside the USFWS. The major products are an annual reporting memo–automatically generated from an R Quarto document, and 19 species-specific comma delimited table files that appear in the memo, and the generating R (.rmd) code.

The daily flight tracks of the 1997-2002 aerial summer Southeast Alaska Nearshore Waterbird Survey were recorded to an onboard computer using the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired). The tracks were recorded by capturing the plane’s location from a GPS every five seconds as long as the software was running. The software was started at some time between the aircraft’s engine start and the start of the survey, and was shut down at some time between the end of the survey and engine shut-down. The tracks thus include the aircraft’s flight to and from the airport base. The 29 track files are named TRMMDDYY_AIR.csv, where MM = month, DD = day, and YY = year.

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...

The daily boat tracks of the 1997-2001 summer skiff-based double-sampling surveys were recorded to an onboard computer using the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired). The tracks were recorded by capturing the skiff’s location from a GPS every five seconds as long as the software was running. The software was started at some time between the boat’s engine start and the start of the survey, and was shut down at some time between the end of the survey and engine shut-down. The tracks may thus include the boat’s travel to and from the home base. Note that the following boat tracks are missing: all 1997 tracks; one track on 08/12/1998; one track on 08/08/2001; one track on 08/09/2001.
