Since 2005, Spray underwater gliders have been used to sample sections across the southern California Current System (CCS). Properties measured are depth‐averaged velocity and profiles of temperature, salinity, Acoustic Doppler Profiler shear, chlorophyll a fluorescence, and 750‐kHz acoustic backscatter. Although slow and carrying a relatively small sensor suite, gliders observed multiple 350‐700‐km sections that reveal detail...
