Mooring (oceanography)

Mooring as deployed in Fram Strait with top buoy, a CTD-sensor, two rotor current meters, acoustic release and train wheels as anchor.

A mooring in oceanography is a collection of devices connected to a wire and anchored on the sea floor. It is the Eulerian way of measuring ocean currents, since a mooring is stationary at a fixed location. In contrast to that, the Lagrangian way measures the motion of an oceanographic drifter, the Lagrangian drifter.
