Lagrangian analysis is the use of
Lagrangian coordinates to analyze various problems in continuum mechanics.
Lagrangian analysis may be used to analyze
currents and
flows of various materials by analyzing data collected from gauges/sensors embedded in the material which freely move with the motion of the material. A common application is study of
ocean current
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, sh ...

Oceanography (), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
It is an Earth science, which covers a wide range of to ...
, where the movable gauges in question called
Lagrangian drifters.
Recently, with the development of high speed cameras and particle-tracking algorithms, there have also been applications to measuring turbulence.
