Abstract The Drifting Buoys GDAC -Global Data Assembly Centre- is the repository of surface drifters data. Both NRT -Near Real Time- and DM -Delayed Mode- data are available on the GDAC. Drifters report generally trajectories, sea-surface temperatures, atmospheric pressures at sea-level, as well as sea-surface salinity or sub-surface temperature in the ocean top layer.

Lineage Most drifting buoy data are acquired in Near-Real-Time within a few minutes via satellite telecommunication.
The data are then complemented with metadata, and quality controlled.
Regularly, the GDAC reprocesses its data holding to update the quality control on past data.
There are several drifter data repositories for redundancy, see the DBCP 'Access to Buoy Data' page (http://www.jcommops.org/dbcp/data/access.html)
Utilisation No limitations on public access
