Hello!
The garbage patchs are a site with high concentrations of trash. They are formed by the ocean gyre, where the ocean have convergences zones forming a circle of currents. When the garbage join the circle, it can't go out, cause the currents make a kind of a permanent "wall".
We can locate garbages patchs in the South Atlantic Gyre, Indian Ocean Gyre and the South Pacific Gyre.
Hugs!
