Lagrangian Drifters

Today’s research led me to learning about various ways to study ocean currents, using either the Lagrangian or Eulerian method of measurement. You can set something in the water and let it drift with the current (getting “Lagrangian measurements”) or you can set up something stationary and study the water that moves past it (getting “Eulerian measurements”). Kind of obvious once you think about it – both are necessary to really understand flow dynamics.

I may be doing something with Lagrangian drifters in the future so this is fascinating to me.
