Upon his June 8 return from a 21-day mission to the Northwestern Hawaiian Islands, also known as Papahanaumokuakea, aboard the NOAA ship Hi‘ialakai, Sustainable Coastlines Hawaii director Kahi Pacarro says he's hoping to return again to clear even more of it from those remote isles.
NOAA partnered with Sustainable Coastlines Hawaii for a pilot project to pick up terrestrial marine debris and plastics from the beaches of Kure Atoll, Lisianski Island, Pearl and Hermes Atoll and French Frigate Shoals during three weeks in May and June. As part of the project, the types and sources of debris will be identified, along with an estimate of accumulation rates.
In total, the team hauled back about 5,000 pounds of debris — large pieces of plastic, buoys, and nets. Most of it will be recycled and used for an installation art piece, according to Pacarro.
The Green Leaf sat down for a Q&A with Kahi.
Q: How did you end up going on this trip with NOAA?
A: The Hawaiian Monk Seal Research Program goes out every year and leaves as a full boat, drops off field teams and supplies and comes back with a barebones crew. They saw an opportunity, and said, why don't we start bringing back some of the marine debris on the way back? They thought of my organization because they've seen us get the work done and pick up marine debris versus just talking about it. That's kind of how it started.
Q: Was it a challenge?
A: For us, it was figuring out where the marine debris was coming from, how to put it on a small boat, how to get it from reef to boat, how to make sure it's stored safely, how to get it off the boat and into a storage facility...The NOAA marine debris program focuses on entanglement hazards, so that's going to be nets floating on nearshore waters, nets on shores and beaches, and those attached to reefs...Then there's the terrestrial plastic polluting the beach. That's the stuff the Monk Seal Research Program team has to walk by on a daily basis to check on the monk seals...So we picked up those piles, and ended up bringing back about 5,000 pounds of marine debris.

Q: What will you do with 5,000 pounds of that marine debris?
A: We'll be incorporating them into the state's largest marine debris art installation at Thomas Square (in time for) the 2016 IUCN (Sept. 1-10) conference. When completed, it will be recycled through our partnerships with Method and Parley for the Oceans. Whatever they can't take, ropes and what not, if we don't have a source for somebody to recycle it, it will go to our trash energy program...
Q: Since this was your first time out there, what was your first impression? What was the most interesting observation you made out there?
A: The first place we landed was Tern Island at French Frigate Shoals...There were so many birds. It was like stepping into a National Geographic television show...They're everywhere, and you have to look where you step because there are eggs everywhere. It's a very fragile ecosystem. One false step and you've killed a baby bird.
Q: What about the amount of marine debris out there?
A: What I saw was the dirtiest beach I'd ever been to, and that was on Laysan. It must have been accumulation of plastics since the invention of plastics. It was the dominant feature of the landscape. It outnumbered birds. The birds just live amongst it, and so do the [Hawaiian monk] seals, and so do the turtles. They live with this marine debris and they become dull to it just like society becomes dull to it. What we have to do is raise awareness...

When we did our first beach cleanup, there were only eight of us cleaning this south section of Lisianski island, this thing was three or four football fields, and there was marine debris everywhere. There was no way eight of us were going to make a dent in this zone. We said, 'You know what? Let's just try.' Within six hours, we had that area completely clean... We just put out heads down, drank a lot of water and pt on a lot of sunscreen. It was really hot, but it was so rewarding...We created this technique, using old ropes to string up the [commercial fishing] buoys like they were a 200-pound lei, and like football players pulled them up oto the high tide line where they couldn't be easily washed away. Knowing we could up that much area with so few people gives you hope...
Q: Was it an eye-opener for you, even though you already deal with marine debris at your beach cleanups?
A: Yeah, definitely. I didn't expect there to be that much trash. Some key things that stuck out in my mind were the amount of commercial fishing gear that was out there...I saw multiple smart FADs (Fish Aggregating Devices) used in the commercial fishing industry...It's like a dome, it floats, has a solar panel, electronics within with sonar testers that can be calibrated to determine how many fish are underneath...it also has GPS coordinates...We saw at least 100 FADs out there...We looked up these companies and their focus is on bluefin tuna. I eat so much tuna. I love spicy ahi donburi — now what am I supposed to do because I am contributing to this problem? It's a tough realization, yet I am contributing to this problem on a large-scale by firing up on spicy ahi donburi, unless it's coming from my local fisherman... It comes down to regulation, it also comes down to us as consumers...
Q: What type of marine debris did you find most of out there?
A: I was expecting to find a lot of single-use plastic water bottles out there. The only bottles making it out there were bottles where the cap was left on. Every single bottle that we found out there had a cap on it...That means that billions of bottles that do make it into the ocean are sinking to the bottom and lining the ocean floor...The No. 1 trash items were from the hag fish and oyster industries...Hag fish traps and oyster spacers, then buoys...And we still found a lot of [plastic] straws, a lot of toothbrushes and a lot of razors, even deodorant.

Q: How does this change your perspective on marine debris and your mission at Sustainable Coastlines Hawaii?
A: It strengthens our existing desire to clean more marine debris, increase recycling of marine debris using what's existing versus virgin products, along with being better consumers, and using the power of our wallets to effect change within our society. That transcends beyond marine debris and plastics. That goes into what you eat, what you eat it out of, energy, where you get your energy from...
Q: Will you return to Papahanaumokuakea next year?
A: I sure hope so...Potentially, next year what we'd like to do, is probably have one of us on the boat for the whole time. When it gets to Midway, have a crew of our own meet them there and come down as a team to exponentially increase the amount of marine debris we can pick up...
PUT IT ON YOUR CALENDAR
