Purpose

These scripts create daily survey station daily temperature and anomaly
plots as the ships work their way through the Bering Sea. These ships
are conducting NOAA Fisheries’ Alaska Fisheries Science Center’s
fisheries independent surveys in the Eastern Bering Sea. Scripts pull
temperatures from google drive, entered by FPCs at sea, create daily
maps and composite gifs, and then push the maps to google drive for the
communications team. These plots are displayed on the AFSC website

Notes

• You will need to install
  ffmpeg so
  video files can compile using the
  magick
  package, which works well with Task Scheduler. The av R package does
  not seem to work with task scheduler.
• How to set up the task
  scheduler
• Files are saved to our internal dev FTP server and google drive.
• Troubleshooting: if the task scheduler fails to run the code, but you
  can run the script in R or Rstudio, you may need to update Pandoc. If
  you are on a NOAA machine, ask IT to install the .msi file for you.
  Close and reopen everything and try again.
