Ocean Cleanup Diving in Korea: One Day Pulling Ghost Nets at Namae Beach

Ocean Cleanup Diving in Korea:
One Day at Namae Beach

Divers from Fourth Element, Peugeot and NB Divers went into the East Sea to pull out the nets that keep fishing long after everyone has stopped.

Ghost Nets Do Not Stop Fishing

Behind the mesh of an abandoned trap, a fish was still alive. It had swum in and could not find its way out. If nobody had gone down that day, it would have died there — not caught by anyone, just forgotten by everyone.

Lost and abandoned fishing gear — divers call it ghost gear — keeps trapping marine life for years. Add the estimated twelve million tonnes of waste entering the sea every year, and the water we love diving in Korea needs more than admiration. It needs hands.

What Ocean Cleanup Diving in Korea Looks Like

On 19 July 2024, instructors and crew from Fourth Element Korea, NB Divers and Namae Scuba Resort met at Namae Beach in Yangyang, Gangwon-do, with vehicle support from Peugeot. Everyone came as a volunteer. After lunch together and a safety briefing from the resort’s owner, the group split into scuba and freediving teams and went to work.

Scuba and freediving teams worked the same site in rotation — organised, briefed, and in buddy pairs.

The East Sea did what the East Sea does: the temperature dropped without warning and the visibility closed in. The teams stayed on task — cutting, lifting and hauling — and recovered a serious quantity of derelict nets and traps. A few fish found alive inside were released on the spot.

Fourth Element, the British dive brand behind the OceanPositive line, builds much of its range from recycled ghost nets, plastic bottles and old carpet — and backs marine charities like Ghost Gear, Reef-World and the Coral Restoration Foundation. Peugeot supports international marine-protection projects, from protected-area networks to research on ocean plastics, and put its cars at the crew’s disposal for the weekend.

Strangers at breakfast were buddies by noon. Between briefings and surface intervals, it felt less like a work day and more like one of our dive trips — with a purpose attached.

why we keep showing up

Diving Is Our Culture

NB Divers has been training divers in Seoul since 2000 — slowly, in small groups of one to three students, with staff instructors who each carry more than a decade of teaching. Our teaching and consulting team is led by women, and our dive professionals communicate in English, as well as Korean and Japanese. We believe education carries responsibility with it: learn it slow, keep it forever applies to the ocean, not just to skills. Not for everyone, only for you.

How Any Diver Can Help

You do not need an event, a sponsor or a slogan. Think of the sea as your own room: clean a little, often, and it is never a mess when guests arrive. On any dive, that means three habits:

  • Pick up one piece of trash per dive — one piece, every dive.
  • Leave heavy nets and lines to trained hands; report them instead of pulling.
  • Keep your buoyancy sharp so you can work near the bottom without touching it.

That last one is a skill, and it is trainable. Good buoyancy and rescue awareness are exactly what the next courses after Open Water are built around — they are what make a diver useful, not just present, on a cleanup. If you are not certified yet, the path starts with an Open Water course; the ocean can always use one more pair of trained hands. With action, there is hope.

Dive With a Purpose

Curious about cleanup dives, or about learning to dive well enough to join one? Ask us anything — the consultation is free, there is no registration needed to ask, and nobody will push you into a course.

Questions About Cleanup Diving in Korea

What is a ghost net?
A ghost net is fishing gear that has been lost or abandoned at sea. Because modern nets are made of plastic, they keep trapping fish, crabs and other marine life for years — long after anyone benefits from the catch. Removing them is one of the most direct ways divers can help the ocean.
Do I need a special certification to join an ocean cleanup dive?
For most cleanup events an Open Water certification with solid buoyancy control is the practical minimum, and net-cutting work is handled by experienced divers. Programmes like PADI’s Dive Against Debris specialty teach the survey and recovery side properly.
Can beginners take part?
Yes — shore support, sorting recovered gear and shallow-water roles are real contributions. In the water, newer divers are paired with experienced buddies and given simple, safe tasks. Nobody is sent to cut nets on their first sea dives.
Where do cleanup dives happen in Korea?
Anywhere divers dive: the East Sea coast of Gangwon-do (this event ran at Namae Beach in Yangyang), Jeju Island and the South Sea. Local dive resorts usually host, because they know their sites and where derelict gear collects.
Is the East Sea cold?
It can be, even in July — thermoclines can drop the temperature suddenly at depth, as they did during this event. With the right exposure suit and a briefing from people who dive the site often, it is entirely manageable, and the marine life makes it worth it.
I live in Korea but do not speak Korean. Can I still join?
Yes. Our dive professionals communicate in English, as well as Korean and Japanese, and briefings can be given in English. Many of our students and fun divers are expats living in Seoul.
What is Fourth Element OceanPositive?
OceanPositive is Fourth Element’s commitment to make diving good for the ocean: producing gear from recycled ghost nets and plastic waste, extending product lifespans to reduce throwaway consumption, working toward carbon neutrality, and funding marine conservation charities.
What happens to the recovered nets?
They are hauled ashore, sorted and sent for proper disposal or recycling. Some recovered fishing nets worldwide are recycled into new material — including fabric used in dive gear.
How do I get certified so I can join the next one?
Start with the PADI Open Water Diver course, then build buoyancy and rescue skills through Advanced-level training. We teach in small groups of one to three students, so your pace is the pace. Stop partway through a course and you are billed only for what you did, with the rest refunded.
