This week, four saildrones departed from Hawaii on the second mission to the equator in an effort to improve the Tropical Pacific Observing System (TPOS).  NOAA forecasts a 50-55% chance of a weak El Niño developing during September - November 2018, increasing to 65-70% chance during winter 2018-19. The second saildrone mission will thus capture ocean and atmospheric data during this developing El Niño, including changes in ocean temperature, winds, currents and ocean carbon dioxide concentrations.

During the first mission in late 2017-early 2018, La Niña conditions were present. Strong currents and low winds on the equator made navigation challenging. This year, two of the four saildrones have been outfitted with larger, more... more
