DESCRIPTION:Pr. Thomas Peacock is Associate Professor in Mechanical Engine
 ering at MIT\, USA. His current research interests are Internal Waves\, St
 ratified Flows\, Nonlinear Dynamics\, Fluid Dynamics and Experimental Meth
 ods.\nRecent years have seen several major environmental disasters through
 out the Earth’s oceans\, such as the the Deepwater Horizon oil spill and
  the Tohoku Tsunami that caused the release of substantial amounts of debr
 is and radioactive contamination. In each of these disasters\, material wa
 s released from what was essentially a point source into a background flow
 \, and understanding how this material would be transported by the flow wa
 s of paramount importance.\nIn order to predict the outcome of events such
  as these\, the standard approach is to run numerical simulations and use 
 the resulting velocity field data sets to generate predicted trajectories.
  Whilst certainly a powerful predictive tool\, the resulting trajectories 
 can often be convoluted\, resulting in “spaghetti plots” that are diff
 icult to interpret. More significantly\, the trajectory analysis approach 
 provides little explanation as to 'why' things evolve the way they do.\nTo
  improve understanding and forecasting\, therefore\, there is a pressing n
 eed to develop new concepts and methods that provide deeper insight regard
 ing flow transport. We present an overview of novel approaches for uncover
 ing the underlying skeleton of Lagrangian transport. Both idealized and re
 al world examples are used to demonstrate the methods.
