Pacific Ocean garbage patch worries researchers



By MICHELLE RINDELS, Associated Press Writer Michelle Rindels, Associated Press Writer – Fri Aug 28, 1:16 am ET

LOS ANGELES – A tawny stuffed puppy bobs in cold sea water, his four stiff legs tangled in the green net of some nameless fisherman.

It's one of the bigger pieces of trash in a sprawling mass of garbage-littered water, known as the Great Pacific Garbage Patch, where most of the plastic looks like snowy confetti against the deep blue of the north Pacific Ocean.

Most of the trash has broken into bite-sized plastic bits, and scientists want to know whether it's sickening or killing the small fish, plankton and birds that ingest it.

During their August fact-finding expedition, a group of University of California scientists found much more debris than they expected. The team announced their observations at a San Diego press conference Thursday.

"It's pretty shocking — it's unusual to find exactly what you're looking for," said Miriam Goldstein, who led fellow researchers from the Scripps Institution of Oceanography at UC San Diego on the three-week voyage.

While scientists have documented trash's harmful effects for coastal marine life, there's little research on garbage patches, which were first explored extensively by self-trained ocean researcher Charles Moore just a decade ago. There's also scant research on the marine life at the bottom of the food chain that inhabit the patch.

But even the weather-beaten, sunbleached plastic flakes that are smaller than a thumbnail can be alarming.

"They're the right size to be interacting with the food chain out there," Goldstein said.

The team also netted occasional water bottles with barnacles clinging to the side. Some of the trash had labels written in Chinese and English, hints of the long journeys garbage takes to arrive mid-ocean.

Plastic sea trash doesn't biodegrade and often floats at the surface. Bottlecaps, bags and wrappers that end up in the ocean from the wind or through overflowing sewage systems can then drift thousands of miles.

The sheer quantity of plastic that accumulates in the North Pacific Gyre, a vortex formed by ocean and wind currents and located 1,000 miles off the California coast, has the scientists worried about how it might harm the sea creatures there.

A study released earlier this month estimated that thousands of tons of plastic debris wind up in the oceans every year, and some of that has ended up in the swirling currents of the Great Pacific Garbage Patch.

Katsuhiko Saido, a chemist at Nihon University, Chiba, Japan, told the annual meeting of the American Chemical Society last week that plastic actually does decompose, releasing potentially toxic chemicals that can disrupt the functioning of hormones in animals and marine life.

The Scripps team hopes the samples they gathered during the trip nail down answers to questions of the trash's environmental impact. Does eating plastic poison plankton? Is the ecosystem in trouble when new sea creatures hitchhike on the side of a water bottle?

Plastics have entangled birds and turned up in the bellies of fish, and one paper cited by the National Oceanic and Atmospheric Administration estimates 100,000 marine mammals die trash-related deaths each year.

The scientists hope their data gives clues as to the density and extent of marine debris, especially since the Great Pacific Garbage Patch may have company in the Southern Hemisphere, where scientists say the gyre is four times bigger.

"We're afraid at what we're going to find in the South Gyre, but we've got to go there," said Tony Haymet, director of the Scripps Institution.

Only humans are to blame for ocean debris, Goldstein said. In a blog entry posted a day before the science ship arrived in Newport, Ore., she wrote the research showed her the consequences of humanity's footprint on nature.

"Seeing that influence just floating out here in the middle of nowhere makes our power painfully obvious, and the consequences of the industrial age plain," she wrote. "It's not a pretty sight."

"The Great Pacific Garbage Patch"

This is the first time I have ever heard the term or of it's existence. Oh, I have been aware of oil spills and pollution in the water and the danger to sea life.

"The Great Pacific Garbage Patch"

A foreboding title.

Also contributing to this delima, are "Cruise Ships"!!! Two years ago we were on a cruise, & I was getting myself a tan on the fantail section of the ship. And low & behold, I looked out into the ocean, and see at least "40" or more 50 gallon black plastic bags floating behind the ship. So I got up to look over the side to see what I could see, and what do I see, those same black bags being thrown out of a door way from the kitchen area. After a while the bags sank, but consider how many cruise ships are in the ocean daily, doing the same thing every day, on the cruise out, and then on the cruise back!!! Alarming!

I hate to see the barges dumping garbage into the sea. But, I certainly don't see any great solutions as we throw away so much garbage each day:mad: I'm trying hard to reduce.reuse.recycle, but it is hard to do at times.



The gargage barges are supposed to go 100 miles out to sea and dump garbage, but not anything toxic......~~~~~sure:thinking:~~~~~



Anyway, they don't go out that far. When you dive into the ocean at times, you surface surrounded by garbage.....gum wrappers, soda cans, plastic, cut down trees and other nasties....:mad: Yuck....

There's a great documentary on plastic called "Addicted to Plastic" that goes into depth about the garbage patch, and has some disturbing footage of it.
