The scientists did not find only the rigid microplastic shards and beads typically studied on the ocean's surface, but also tiny plastic fibers shed from synthetic clothing.

Analysis of the 51 samples taken found that there was an average of 1.26 microplastic pieces per gram of sediment. Researchers say that’s up to 25 times more microplastics than previous deep-sea ...

Researchers have successfully revived algae that remained dormant within sediment at the bottom of the Baltic Sea for more than 7,000 years. The tiny diatom cells have regained full biological ...

"In this way, the deep sea becomes the 'final repository of waste'." The researchers found a total of 14 different types of plastic in the samples from the Kuril-Kamchatka Trench.

So far, the data have revealed a landscape about 3,861 square miles (10,000 square km) west of the Orkney-Shetland Islands that stretched above sea level by almost as much as 0.6 miles (1 km).

Hagfish also love to burrow into the deep-sea sediment, but scientists have been unable to observe precisely how they do so because the murky sediment obscures the view.
