In Images: The Great Pacific Garbage Patch

Massive garbage patch

Trash island

Here, an up-close look at the "Shark Island" (so named because of its appearance). Buoys, anchors and ropes washed to sea when the 2011 Japanese Tsunami inundated aquaculture boats may have formed the island, researchers hypothesize.

Trash adrift

Moore first discovered the trash while returning from a yacht race in 1997. Here, a gas tank bobs in the middle of the Pacific Ocean.

In a new expedition, Moore's team has found plastic debris in places they didn't expect to.

Secret life

Past research has found that a secret world of microbes and microorganisms lives on the plastic detritus in the ocean. Here, scientist Greg Boyd (from a separate expedition) shows the sea life that has colonized foam floats.

Deeper Ocean

A 2014 paper found that the ocean plastic is mysteriously disappearing, possibly because it is being carried deep into the ocean, like this trash bag found deep below an underwater canyon off the coast of Monterey, California.
