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.
