A huge current rotates in the Pacific Ocean, causing floating plastic trash to gather in a giant vortex of garbage in the middle of the ocean – it’s become the world’s biggest dump. Project Kaisei has sent two ships to the area to study the problem. Doug Woodring is on the New Horizon. He talked with Lester Graham by satellite phone:

Lester Graham: You’re in the middle of the Pacific right now, looking for the Great Pacific Garbage patch. How much luck have you had in locating some of this plastic debris?

Doug Woodring: Unfortunately, too much luck. (laughs) It hasn’t been very difficult. In fact, I’m running into, ah, I can look out the window and see a big floating piece, right now, as we’re going by. But we’ve been, the last 5-6 days, we’ve been in it consistently. It’s not as many big pieces as the world might think, but it’s way many more small pieces than people know. And the reason is, with the UV dedrigation in the plastics, it get very brittle when it’s broken down by the sun, so after some time in the water, when the wave action, it’s very easy for everything to break down and sort of crack. So what we’re getting is what they call ‘confetti’, and it’s just literally in some places many, many pieces per square meter of this stuff. And we are really looking mostly at the surface, so it’s not known yet how deep this is either. So, there’s a lot of stuff out here.

Graham: Why’s this bad for the environment?

Woodring: When you get small pieces, you’ve got mistaken potential food source for animals. So, the marine life can be eating this. It is possible that it gets in the food chain. There are toxins, heavy metals, and persistent organic pollutants that attach themselves to plastics when they float. So, it’s not just a piece of plastic that a marine life eats, it’s a polluted piece of plastic. It’s also a little island, or a little flotation for species that can float around the ocean – and invasive species can go to different parts of the waters or land that wouldn’t have traveled that way otherwise. So, there’s a lot of implications that this science is only just now starting to help us figure out what’s going on.

Graham: Does anybody have any idea what we can do to reduce the impact of this huge garbage patch or to clean it up?

Woodring: Well, this is what we’re out here for. That’s the main part of our mission is to find solutions. And we can’t find solutions until we have some of the answers, and some of the data. So what we’re out here is with two vessels now, over a 30 day period, really looking for that data – water depth, leadings and temperatures and flows and salinity – to see how the plastics and the material, the debris might move around in the ocean. We will, later, be doing some analysis on the material, science of the plastics, to see if it’s recognizable by satellite. Because, obviously, without satellite imagery, it’s impossible to know exactly where the bigger masses are. You know, ‘how to clean it up,’ is going to be a very tricky thing, because the oceans are so big and these particles are not big. It’s all going to come back to what we’re doing on land, really, and the land policies for different ways to bring in better recycling and rebate programs to get a lot of the plastic that is out there today to be reused instead of simply thrown away, and so it doesn’t get into the rivers or the oceans in the first place.

Doug Woodring is a co-founder of Project Kaisei. He spoke with The Environment Report’s Lester Graham.
