ROVs Discover Deep Sea Trash

An anonymous reader writes "Deep beneath the ocean's waves, strange creatures such as rockfish and gorgonian coral thrive in the icy depths. Yet there's something else you'll find if you go searching beneath the sea: trash, and lots of it. Researchers have discovered that our trash is accumulating in the deep sea, particularly in Monterey Canyon off of the coast of California. Scientists knew that trash was affecting shallower depths--about 1,000 feet beneath the water. Yet they were unsure whether the effects extended to the truly deep parts of the ocean that reached up to 13,000 feet. They decided that there was only one way to find out: look for themselves."

      If we can find it we can probably pick some of it up. Stuff like that cargo container probably fell off a ship on accident though and probably weighs a ton. I bet hurricanes, weather, floods, tsunamis, and other events contribute to the problem as well. I know if a tsunami hit my city (can't) but it it did it would dump a lot of trash into the ocean. And we do get hurricanes and tropical storms. I wouldn't be surprised to find a refrigerator out there somewhere that wasn't from a wreck.

      It would be interesting if they had some stats other than percentages. Like 3000 plastic bags or 10,000 aluminum cans. And maybe some estimated trash densities based on what they have found so far.
