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.

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.

NOAA Fisheries AFSC Groundfish Assessment Program conducted the Aleutian Islands bottom trawl survey. The near real-time ocean bottom temperatures depicted were collected June 7-June 21 On June 21, stations 237-36 (52.52°N, -172.26°W; >3.5–4°C), 236-36 (52.52°N, -172.34°W; >4–4.5°C), and 238-37 (52.57°N, -172.18°W; >3.5–4°C) were surveyed by the F/V Ocean Explorer. No stations were surveyed by the F/V Alaska Provider. Credit: NOAA Fisheries

The near real-time ocean bottom temperatures depicted were collected May 31-June 22 On June 22, three stations were surveyed by the F/V Northwest Explorer. No stations were surveyed by the F/V Alaska Knight. There are 8 stations planned for June 23 Credit: NOAA Fisheries
