New rules on trash disposal at sea address a growing problem Sep 26, Kelly Sweeney My first seagoing job was as a deck hand with a large West Coast towing company.
Trash is collecting on the Arctic seafloor One part of the ocean floor has 20 times more litter than a decade ago Sharon Oosthoek Mar 24, — 7: The flower-like animal is a sea lily. Melanie Bergmann Researchers and fishing crews have found a lot of trash floating in the world's oceans over the past few decades.
That trash has even shown up in the remote Arctic Ocean. Now a study shows there is also trash deep down on the Arctic seafloor. Though few people live nearby, researchers found plastic bags, shards of glass and fishing nets. And the litter problem is getting worse. We wanted to look at the deep seafloor," says Melanie Bergmann.
Bergmann and her colleagues also wondered how that ocean trash might be changing over time. And the short answer: Each year from toBergmann and her team took pictures of the seafloor at two places in the Fram Strait. This is a narrow stretch of the Arctic Ocean between Greenland and Svalbard, a Norwegian island group in the far North.
The researchers lowered cameras down to 2, meters about 1. Those cameras snapped photos every 30 seconds. To date, the scientists have taken 7, photos.
Those pictures turned up 89 pieces of litter. That may not seem like a lot. This surprised the scientists because there are far fewer people living in the Arctic than in Portugal.
There are also worrying signs that the trash there is growing. Where did the trash come from? Bergmann suspects that the bits of glass they saw came from boats.
A warming climate is melting sea ice in the far North. And indeed, shipping traffic there has been increasing.
People on those boats are probably dumping their garbage in the water, either on purpose or accidentally, Bergmann thinks.
Because glass is denser than water, it quickly sinks to the bottom.again becomes a matter for discussion in the international forums. Radioactive wastes have been dumped at some 47 sites in the north Pacific and Atlantic oceans, and in the Kara Sea in the Arctic.

In response to the problem of garbage at sea, the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78), Annex V, came into force in For the first time, there were restrictions on where and what type of trash could be dumped into the oceans.
For centuries, the oceans have been a convenient dumping ground for waste generated on land. This continued until the s, with dumping at sea the accepted practise for disposal of nearly everything, including toxic material such as pesticides, chemical weapons, and radioactive waste.
