Lagrangian current measurement


Show Summary Details

Quick Reference

A technique for measuring water movements by tracing the path of a water particle over a long time interval. A device is released into the water and allowed to drift passively with it. Measurements can be made, e.g. by following and plotting the progressive position of a neutrally buoyant float for subsurface currents, or a drift pole or buoy for surface-water movements.
