The Great Pacific Garbage Patch isn't what you think

Summary

• The Great Pacific Garbage Patch is not a solid island or a visible floating mat of trash. It is a broad area where currents converge and concentrate plastic in a gyre, a large rotating current system.
• Plastic is dispersed and can be found at different depths, so it may not be visible even when a vessel is within the patch. Debris includes larger objects such as abandoned fishing nets, bottles, and crates, as well as natural materials such as sticks and wood.
• Ultraviolet radiation from sunlight, wave action, and contact with reefs, rocks, and sand break larger plastic items into smaller fragments.
• Because the debris is dispersed and partly below the surface, the patch is difficult to clean up. A compact “garbage island,” by contrast, would be easier to remove.
