Database Update Status

September 1, 2018:

The GDP database has been updated through June 30, 2018. Download All
To downlaod a subset of this database, either by region, time, or drogue pressence, visit Data Subsets

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.

Outreach Activities

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.

A news item in EurekAlert,the news service of the AAAS, highlights a recent study that uses drifter data to improve our understanding of how ocean garbage gyres form. The study was lead by Francisco Beron-Vera of the University of Miami.
