Meteorological observations and context of the 2017 Antarctic Circumpolar sailing campaign OceanoScientific

This animation shows the locations of air pressure meteorological data collected by the 2017 OceanoScientific sailing campaign under the 40th Southern parallel in the Antarctic Circumpolar Current.

Each second of the animation includes 24 frames. On each frame, the dots show locations of air pressure data within 12 hours of the date and time indicated (respectively) at the bottom and right-hand-side. The various colors differentiate between the origins of the data, as received from the Global Telecommunication System (GTS): red for OceanoScientific, green for other Voluntary Observing Ships (VOS), and blue for data buoys. The contours represent 6-hour moving averages of mean-sea-level pressure from the ERA5 reanalysis.
