Why are plastic amounts so different in bodies of water so close together?

One reason for amounts of plastic to differ from place to place is the formation of eddies, smaller spirals of current within the gyre.  Because the gyre is so large and the wind and currents are so dynamic, there is not one central location of plastics.  Windrows of plastic can also form on the surface that are similar to snowdrifts or sand drifts on a beach.  The largest concentration we’ve seen by far were collected along a windrow.
