As part of the ONR-funded ’Northern Arabian Sea Circulation—autonomous research (NASCar)’ DRI, spray gliders surveyed from the northern edge of the Mascarene Plateau, crossing the equator repeatedly, then surveyed southward back toward the Seychelles prior to recovery. One glider mission was conducted in each of 2017 and 2018. Missions were timed to capture the onset of the southwest (northern hemisphere summer) monsoon at the equator. Additional plots of these data are available at


All the data for this project is available in CF compliant netCDF(s), thus ancillary metadata is embeded inside those.
