The Alaska Swan Survey Protocol was first developed by MBM-AK (James G. King, retired) in the 1960s to describe a standardized method of conducting aerial swan surveys in Alaska. Documentation of the protocol was last updated in 2007. All the swan survey data in the Alaska Swan Database were collected using this protocol.

From 1981 to 2009, MBM-AK collaborated with its partner, U.S. Forest Service Cordova Ranger District, to conduct spring nesting and late-summer trumpeter swan surveys on the Copper River Delta, Alaska. An annual summary report was produced by MBM-AK. As of the date that this metadata was written, only the 2004-2009 reports were available in digital format and archived in the FWS Alaska Regional Data Repository (AK_Swan_Database project). All the reports in paper format are available upon request from MBM-AK (see contact information elsewhere in this metadata).

The Alaska Trumpeter Swan Survey data files (AK_TRUS_Data_YYYY.csv, where YYYY = survey year) include a field called “Contrib,” which indicates the organization that collected the data. Each organization is identified by a numeric code. Contrib_Codes_AK_TRUS_Survey.csv defines the data-contributor codes that were entered in the Contrib field.

This is the GeoPackage (“TMG_AdditionalAreas.gpkg”) that contains the layer (“main.TMG_NewAreas”) depicting the spatial extent of the four Additional Survey Areas that are assessed during the annual MBM-AK TLSA molting goose aerial surveys. This GeoPackage (NAD83; ESPG: 3338) was created by Michael Swain in August 2021 and subsequently emailed to Maggie Harings. It includes waterbody units, waterbody types, and waterbody perimeter as well as their areas.

This collection of files contains the reports that were produced when the raw data were quality-checked against the defined standards in the “Transcribed Data Dictionary” using the “GreenLight” function of the R Package “AKaerial.” The QC log files document the quality control process, data standards, and what changes (if any) were made in the QC data compared to the raw data. Each log file was named following the same file naming conventions: SSS_YYYY_QCLog_OOOO_yyyy-mm-dd, where; YKD = Duck data, YKG = Goose data or YYY=Year, OOOO = observer’s first initial and last name,yyyy-mm-dd = year, month, and day the AKaerial.R (“GreenLight”) function in was most recently executed
