Practically six tons of marine particles collected from a distant island have been offloaded in Ketchikan on Wednesday. The particles is sure for recycling in Seattle — however researchers hope it may additionally make clear the sorts of rubbish that finds its method into the ocean.
Crews hauled huge material baggage stuffed with rubbish off of the F/V Polar Woman on Wednesday — 11,500 kilos in all. All of it got here from Forrester Island.
That’s an uninhabited islet 40 or so miles southwest of Prince of Wales Island referred to as Gaskuu within the Haida language.
Equipment Cunningham is a technician with the state division of Fish and Sport’s marine mammal program and a graduate pupil on the College of Alaska Fairbanks. She’s finding out the rubbish as a part of a analysis mission for her thesis.
“I wish to know the place the particles is coming from and the way lengthy it’s been within the water,” Cunningham mentioned. “And a method we’re type of wanting into that’s if there’s any development on the marine particles.”
That development is named “biofouling.” Issues like algae, barnacles and the like can provide clues in regards to the origin of the marine particles that washes ashore.
Cunningham’s newest journey to the island comes after she participated in a examine of the island’s Steller sea lions final 12 months.
“There’s at all times been fairly a little bit of trash and marine particles on the market, so it was type of the proper candidate,” she mentioned.
The work was funded by a Nationwide Oceanic and Atmospheric Administration grant program.
Cunningham and two crews, working in shifts, spent simply over a month choosing up trash on the island.
However why does a lot particles pile up on this specific island within the North Pacific? Cunningham mentioned the situation might have one thing to do with it.
“It’s one thing that I’m nonetheless studying about proper now, however I’d guess that because it’s alongside the continental shelf, a variety of currents undergo there — there’s really some actually cool images of storms rolling in,” she defined. “And Forrester, Gaskuu, it’s really the very first thing they hit. So, I feel simply a variety of currents and storms, it’s only a excellent catching spot.”
Alaska Common Seafoods offered two tenders and a skiff for the elimination work. Alaska Marine Traces offered two, forty-foot-long delivery containers to switch the rubbish to Seattle.
Among the many particles have been a couple of glass buoys and bottles — one even had a observe inside.
“It was fairly wild,” she mentioned. “It was really somebody writing to a beloved one who had handed, and simply expressing a variety of love and appreciation for that individual.”
However maybe extra attention-grabbing to Cunningham are the plastics: principally outdated buoys, bottles and Styrofoam.
She mentioned her analysis into the particles may final into subsequent summer time. She’s going to attempt to decide what sorts of plastics have been most typical on the island.
However she’s not simply finding out the trash. Whereas she was on the island, Cunningham collected the vomit samples from sea birds and fecal samples from the Steller sea lions.
She’ll be sending these samples to a professor to see if there are any microplastics within the animal’s diets.
If there are, she defined she desires to study if it’s the identical type of plastic discovered on the island. She mentioned she’s anticipating outcomes later this 12 months.
