ALACE Floats

Autonomous Lagrangian Circulation Explorer (ALACE) Floats were deployed during the 1990s as part of the World Ocean Circulation Experiment.  The floats followed currents for time periods of 10 to 25 days, at depths between 700 and 1100 dbars.  The data in this file are from the Drake Passage region and have been adjusted using regional hydrography to represent values at 900 m depth.

Since the floats spent a day at the surface between each displacement,  consecutive float observations should not be concatenated to form long time series.
