New Model Can Track Movement Of Giant 'Garbage Patches' On Ocean Surfaces

International Business Times, 03 September 2014

 

There are at least five big patches of garbage floating around the planet's oceans and some are as big as the state of Texas, scientists said in a new study, published Tuesday in the journal Chaos. And now, there's an algorithm to track their movements.

 

Researchers from the University of New South Wales, or UNSW, in Sydney, Australia, described a mathematical model to determine which countries are contributing the most to the garbage patches, each of which is located in the center of large, circular ocean currents called gyres that suck in and trap floating debris. Ocean garbage patches formed due to these rotating ocean currents have raised serious environmental concerns because broken plastic, which constitutes a huge chunk of the trash, spreads easily and is toxic to marine life.

 

“In some cases, you can have a country far away from a garbage patch that's unexpectedly contributing directly to the patch," Gary Froyland, a mathematician at UNSW and a co-author of the study said, in a statement. He added that because all oceans are interconnected, garbage from one corner of the globe could travel to the other, riding on ocean currents. Read more....
