“We found that most of the plastic is below the surface.” More, he says, than in the giant floating patches.
And also to their surprise, they found that submerged microplastics are widely distributed, from the surface to thousands of feet deep.
Moreover, the farther from shore they sampled, the more microplastics they found. That suggests it’s not just washing off the California coast. It’s coming from all over.
…The deep ocean is filled with sea creatures like larvaceans that filter tiny organisms out of the water. …”We found small plastic pieces in every single larvacean that we examined from different depths across the water column,” Choy says. Another filter feeder, the red crab, also contained plastic pieces — every one they caught.
…”Anything that humans introduce to that habitat is passing through these animals and being incorporated into the food web” — a web that leads up to marine animals people eat.
