Originally created by Brad Shults, the GitHub repository was created for markdown code used to quality control survey data and create annual survey reports beginning in 2016. The repository can be found on GitHub (‘https://github.com/bsshults/Teshekpuk-Lake-Molt’). A copy of the master branch that was last committed by user “bsshults” (Brad Shults) on 2/24/20 was downloaded by Maggie Harings on 6/29/21 and stored on the Alaska Regional Data Repository (‘GitHub_Annual_Report_Code’). General file naming structure for repository files is: ‘TMGSurvey_Master_[surveyYear]’ Files ending in the file extension ‘.Rmd’ are used to conduct some quality control and data tidying for original survey data. These files contain comments describing the code the precede and should be reviewed prior to using this code. Files ending in ‘.tex’ include markdown code used to generate annual survey reports beginning in 2016. No ‘.tex’ or ‘.Rmd’ files exist for 2020 or 2021 because surveys were not conducted during those summers due to COVID-19 fieldwork-related restrictions.
.’.Rmd’ files read in raw survey data (‘raw_data’) and transect data (‘track_files’), in addition to a ‘lakenumbers.csv’. The ‘lakenumbers.csv’ document has not yet been located but is believed to be a single-column dataset with numbers 1-209 located in said column and could therefore be easily recreated. Following quality control and tidying procedures, the code produces two final datasets (‘TMG_Data_1976_2005.csv’ and ‘TMG_Data_2006_2019.csv’) whose data are used to create figures and tables in annual survey reports. Details of these processes are well documented via in-script comments.
