Many historical drogue off dates have been reevaluated. As of November 2013, the drogue reevaluation project was finished. See Lumpkin et al. (2013) [PDF] for details.
Please note: We now have 4 separate data and directory files, since we exceeded 20,000 records and the original file was getting too large. Some modifications were made to older files, so if you downloaded data prior to May 2016, reload all updated files.
25,000 Drifter Deployments!
NOAA's Global Drifter Program reached a significant milestone: the 25,000th drifter deployment since the start of the program in 1979. The drifter was one of four deployed by Volvo Ocean Race boats off the coast of Brazil during Leg 7 of the race. Worldwide deployments are coordinated by the Global Drifter Center at NOAA's Atlantic Oceanographic and Meteorological Laboratory in collaboration with numerous national and international partners. The drifters measure ocean currents, sea surface temperature (SST), and barometric pressure; these observations improve weather forecasts, ocean state estimation, satellite measurements of SST, and our understanding of how the ocean transports properties, tracers, and debris.
The GDP works closely with various organizations around the world to promote public awareness and increased utilization of drifting buoy data. To learn more about these efforts and GDP partner organizations, please visit our new Outreach Activities webpage.
NOAA's' Global Drifter Program is transitioning the array from Argos to Iridium and including the newer Iridium data in its quality-controlled dataset. Read More
