SUMMARY:Uncovering the Hidden Skeleton of Flow Transport
DESCRIPTION:Featuring Thomas Peacock\, MIT\nHosted by: David Campbell\nPost
	er: http://physics.bu.edu/posters/2013_Fall/1210_Peacock.pdf\n\nPart of the
	 Physics Department Colloquia Series.\n\nAbstract:\nRecent years have seen 
	several major environmental disasters throughout the Earth’s oceans\, suc
	h as the the Deepwater Horizon oil spill and the Tohoku Tsunami that caused
	 the release of substantial amounts of debris and radioactive contamination
	. In each of these disasters\, material was released from what was essentia
	lly a point source into the environmental flow\, and understanding how this
	 material would be transported was of paramount importance. \n\nIn order to
	 predict the outcome of pollution events such as these\, the standard appro
	ach is to run numerical simulations and use the resulting velocity field da
	ta sets to generate predicted trajectories of the pollutant. Whilst certain
	ly a powerful predictive tool\, the resulting trajectories can often be con
	voluted\, resulting in "spaghetti plots" that are difficult to interpret. M
	ore significantly\, the trajectory analysis approach provides little explan
	ation as to 'why' things evolve the way they do. \n\nTo improve understandi
	ng and forecasting\, therefore\, there is a pressing need to develop new co
	ncepts and methods that provide deeper insight regarding flow transport. We
	 present an overview of novel approaches for uncovering the underlying skel
	eton of Lagrangian transport. Both idealized and real world examples are us
	ed to demonstrate the methods.
