Diving groups tackle cleanup of plastic waste

Undersea volunteers remove litter on New York coastline

NEW YORK — A throwaway culture of single-use plastics and other hard-to-degrade material has sullied the world’s waters over the decades, posing a danger to marine life such as seals and seabirds.

Dive by dive, small groups have been trying to undo some of the damage as part of the DIVERS-ity Initiative, which promotes inclusion in the sport.

On a recent Sunday afternoon, the divers arrived on a thin strip of sand at the furthest, watery edge of New York City. Air tanks strapped to their backs, they waded into the sea and descended into an environment far different from their usual terrestrial surroundings of concrete, traffic and trash-strewn sidewalks.

Horseshoe crabs and other crustaceans crawl on a seabed encrusted with barnacles and colonies of coral. Spiny-finned sea robin, blackfish and wayward angelfish swim in the murky ocean tinted green by sheets of algae.

Not all is pretty. Plastic bottles, candy wrappers and miles and miles of fishing line drift with the tides, endangering sea life.

The undersea litter isn’t always visible from the shore. But it has long been a concern of Nicole Zelek, founder of the dive school SuperDive. Four years ago she launched monthly cleanups at this small cove in the community of Far Rockaway, where New York City meets the Atlantic Ocean, about 4 miles south of John F. Kennedy International Airport in Queens.

“Every month we have a prize for the weirdest find,” she said. They have included the occasional goat skull, perhaps used as part of some ritual, Zelek surmises.

“The best find of all time was an actual ATM machine. Unfortunately, it was empty,” she said.

The divers’ haul one late-summer Sunday wasn’t much, but there were clumps and clumps of fishing line untangled from underwater objects. What the divers can’t pull away by hand is cut with scissors.

While more ambitious projects are underway to scoop up huge accumulations of floating debris in deeper waters, smallscale coastal cleanups like Zelek’s are an important part of the battle against ocean pollution, said Nick Mallos, vice president of conservation for Ocean Conservancy.

“The science is very clear, and that’s to tackle our global plastic pollution crisis,” he said. “We have to do it all.”

Every September, the conservancy holds month-long international coastal cleanups. Since its inception nearly four decades ago, the cleanups have retrieved about 400 million pounds of trash from coastal areas around the world.

The best way to combat plastics going into the oceans, Mallos said, is to reduce the globe’s dependence on them, particularly in packaging consumer products. But human-powered cleanup is the least costly of all cleanup options.

By 2025, some 250 million tons of plastic will have found its way into the oceans, according to the PADI AWARE Foundation, a conservation group sponsoring a global project called Dive Against Debris.

The project invites what organizers call “citizen scientists” to survey their diving sites to help catalog the myriad items that don’t belong in oceans, lakes and other bodies of water. By the group’s count, more than 90,000 participants have conducted more than 21,000 such surveys and removed 2.2 million pieces of junk, big and small.

Zelek and her fellow divers have contributed their finds to the project.

Surface trash might be easy enough to clear with a rake, but the task is more challenging beneath the water. Over the years, the layers of monofilament fishing line have accumulated. And until a few years ago, no one was scooping out the line, hooks and lead weights.

Untangled, a pound of medium-weight fishing filament would stretch to a bit more than 4 miles.

“Those small things are really what start to accumulate and become a much larger and bigger problem,” said Tanasia Swift, who has been with the group for a year and works for an environmental nonprofit focused on restoring the health of New York City’s waters.

While the drivers work, fishermen cast their lines from a ledge where the city’s concrete stops. The beach is frequented mostly by residents who live nearby.

Raquel Gonzalez is one such resident, and she’s been coming to the beach for years. She and a neighbor brought a rake with them on the same Sunday the divers were there.

“Needs a lot of cleanup here. There’s nobody that does any cleanup around here. We have to clean it up ourselves,” she said.

“I love this spot, I love the scuba divers,” Gonzalez said. “Look at all the good people here.”
