The Ocean Voyages Institute's sailing cargo ship KWAI pulled into Pier 29 in Honolulu this morning with more than 103 tons of marine trash hauled from the middle of the Pacific Ocean, mission complete despite the ongoing pandemic. The Sausalito, Calf.-based nonprofit, led by Mary Crowley, once again chartered the locally-based, sailing cargo ship KWQAI for the 48-day expedition that set out in early May.
“I am so proud of our hard working crew,” said Crowley. “We exceeded our goal of capturing 100 tons of toxic consumer plastics and derelict ‘ghost’ nets, and in these challenging times, we are continuing to help restore the health of our ocean, which influences our own health and the health of the planet.”
The latest haul is more than double the one from last summer, which culled 42 tons of debris after 25 days out at sea. On last year’s expedition, the institute deployed GPS-enabled satellite beacons, drones and other technology to better track the debris in the ocean, and has found it plays a key role in more effectively removing it. The beacons were placed on nets with the help of crowd-sourced yachts and other commercial vessels, based on Crowley’s theory that one tracker leads to other nets.
Crowley, a lifelong sailor, was hoping to launch a considerably larger expedition this year, with more vessels over a three-month period, but had to scale back due to the impacts of the pandemic. The KWAI, captained by Capt. Brad Ives, nevertheless embarked on the expedition, departing from Hilo on May 4 after a self-imposed quarantine of three weeks.
“We were very careful to keep the crew quarantined, and to test any new crew members coming on board because we wanted to make sure the expedition was safe from a health perspective,” Crowley said.
She hopes the pro-active approach to removing the marine debris in the Gyre — halfway between Hawaii and California — will help spare coral reefs as well as wildlife, including whales, dolphins, and sea turtles from entanglements.
“We feel that our cleanup work in the Gyre really helps address some of this debris before it arrives in the islands,” she said. “The oceans can’t wait for these nets and debris to break down into microplastics which impair the ocean’s ability to store carbon and toxify the fragile ocean food web.”
With the help of Matson, the debris collected, including large piles of ropes and fishing nets and discarded consumer plastics, will be sent to West Coast destinations to be transformed into fuel and repurposed into building insulation.
Crowley is raising funds for another cleaning expedition by the KWAI to the Gyre, expected to depart at the end of June, as well as next summer. She hopes to organize cleanup expeditions to other parts of the world as well.
“Right now when the world is dealing with this very difficult time, it seems so important to pay attention to health on all levels,” she said. “I encourage people to take very good care of themselves right now, to follow all the procedures, to wear a mask, social distancing — all of these things are important. At the same time we should be paying attention to nature and making sure we keep the planet a healthy place to inhabit.”
She noted that the institute’s advisory board member, Sylvia Earle, often cites ignorance, rather than overfishing or garbage, as having the most harmful impact on oceans today.
“Most people don’t realize how closely our own health is tied to the health of the ocean,” said Crowley. “The ocean really produces two out of the three breaths we take. So we need to keep our ocean ecosystem healthy to help us stay healthy and to help the whole planet stay healthy.”
Meanwhile, just north of Hilo on the Big Island, 21 shipping containers have gone overboard from a Young Bros. barge. 2 have been recovered by the CG.
