This is the collection of raw data was collected during MBM-AK TLSA annual molting goose surveys. Partial quality control has been completed for these data: following each survey, the observer listened to their survey recording that documented counts along transects and then transcribed these findings into these raw datasets (‘raw_data’). The observer listened to their recording a second time in order to confirm that their transcriptions were correct. Further quality control and tidying was completed for these raw data using R scripts noted by the file extension ‘.Rmd’ located in the ‘GitHub_Annual_Report_Code’ folder. Ultimately, these scripts produced final datasets (‘final_data’) containing data used in annual survey reports. Generally speaking, raw survey data file names begin with ‘TMG _ [surveyYear] _ RawObs’. Most titles also include other survey details that indicate observers and/or survey location. Because these files are read in by name via GitHub code to produce annual reports, file names have not been standardized. Instead, please reference the linked ‘ReadMe.docx’ under the “Documents” tab for brief explanations of each file.
