S-MODE Saildrone in San Francisco Waters
Sub-Mesoscale Ocean Dynamics Experiment (S-MODE)

As part of NASA’s Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) field campaign, several Saildrones like the one pictured here were launched from San Francisco Bay.

The Saildrones were part of a fleet of autonomous marine research vessels designed to measure a vast array of factors such as ocean currents, wind speed and direction, air and water temperature, salinity, dissolved oxygen, and chlorophyll content.

S-MODE is a NASA Earth mission to use newly developed in-situ and remote-sensing techniques to look at small-scale ocean whirlpools, eddies, and currents. The observations could help scientists better understand how these dynamics drive the give-and-take of material and energy between the ocean and atmosphere and, ultimately, help shape Earth’s climate.
