Diving in the Kelp of South Korea



South Korea

I had fallen behind the group, again, and as I caught up with them they were all gathered round a couple of rocks, looking intently at something. Ralf, our dive guide, was pointing out. As I approached them, they all let me through (they were a lovely group to dive with!) to have a look and here were two beautiful, bright orange nudibranchs, both about six inches long, and certainly not something I expected to see among the kelp whilst diving off a harbour breakwater!

Last year, when I was planning an overseas holiday, I realised that it had been ten years since I last visited my family in South Korea. However, I wasn’t about to go on holiday and not go diving! There wasn’t, and still isn’t, a huge amount of information about diving in South Korea (in English; there’s plenty in Korean, but I read Korean a lot slower than English), but where there’s a will, there’s a way – and through the magic of Google, I booked six days of shore diving; four days off Jejudo with Big Blue 33, and two days off Busan with Busan Seaworld Dive Center. Both had owners/staff who spoke excellent English, so communication wasn’t a problem.

After paying my respects to various members of my family, I was off to Jejudo at the first available opportunity. Jejudo is the biggest island off the coast of Korea and its second biggest city, Seogwipo, has the best diving South Korea has to offer. Situated on the south side of Jejudo, Seogwipo is located in a temperate climate and has a tropical current coming from the south. All the pictures, videos and dive centre information promised that it wasn’t going to be tropical diving, but there was going to be an interesting mix of warm and cold water diving.

South Korea

We didn’t have the most auspicious start to the diving. A recent change in the interpretation of boat licensing laws by the local coastguard had put an end to all boat diving off Seogwipo and a typhoon in the Philippines (a thousand miles away!) was causing a lot of swell and poor visibility. This left us with a massive option of just one place to go diving, off the Seogwipo harbour breakwater. There was a lot of construction work happening in the harbour itself, but the workers had thoughtfully left a big enough gap among the massive concrete bollards for the local divers. The entry point was at the bottom of some concrete stairs, but with the larger than expected swell, getting in and out of the sea was at best, tricky!

However, once I put my head underwater, I knew immediately that I’d enjoy diving here! All the colours I would have expected to see in the Red Sea were swimming around and below me. The visibility wasn’t allegedly great due to the aforementioned typhoon but we still had at least 8 metres (after spending two years solely diving off the UK and Ireland, I rate that as good vis!), but being able to see masked butterfly fish swimming in among the kelp was a first for me and it got the photographer inside me very excited. The sea bed was mainly rocky, covered with boulders and massive concrete jacks from the breakwater, which were covered with kelp and anemones.

South Korea

After we surfaced at the end of the dive, it turned out that I had apparently enjoyed the dive more than the two other divers in group who weren’t too keen to get back in for a second dive. To be fair, the conditions were, if anything, getting worse, so I agreed to call it a day too. The swell was worse the second day, cancelling that day’s diving, which gave me the chance to see some of Seogwipo’s other sights that mainly consisted of some beautiful waterfalls, one of which falls straight into the sea.

Day three was grey and gloomy, but paradoxically, the diving conditions had improved! The Seogwipo harbour breakwater was still the only available dive site, but the visibility had improved to 10 meters and there was a lot more sealife out and about. Also, from a highly personal and photography-obsessed perspective, there were plenty of gobies and scorpion fish around that were willing to pose for a picture! Then towards the end of the day’s second dive, Ralf, my dive guide, pointed out two of the biggest nudibranchs that I’ve ever seen. I’m not the greatest at identifying nudibranchs but I believe that they were a species of Chromodoris. They really made my day and to celebrate a successful day’s diving, the group decided to go and eat a local delicacy, barbecued pork, in vast quantities!

South Korea

Day four in Seogwipo had also started promisingly. There were grey clouds and rain but the sea conditions had improved further and we were able to dive off another site, Weol Pyeong Beach. Weol Pyeong Beach is a cobblestone beach, which is also a popular fishing and picnic spot, a combination which led to occasional remnants of barbecued fish littering the beach, which gave some unwanted clues as to what to expect underwater. However, once we descended, it was brilliant! There was 15 metres visibility and an abundance of sealife. The cobblestones gave way to boulders that marked the edge of the rocky shore and the sandy seabed. There were numerous flounder chilling on the sand, shoals of mullet feeding and even a lionfish lurking in a crevice. There were more nudibranchs – two more of the massive Chormodoris –  another similarly sized Phyllidia, a tiny Bouphonia, numerous gobies and scorpion fish. Ralf took us to an artificial reef where there was some beautiful pink soft coral growing among the kelp. This was to be, by far, the best day’s diving in Korea that I’d get to experience.

South Korea

The water temperature off Seogwipo was 27 degrees, which made my 5mm wetsuit more than adequate! The deepest we reached off the harbour breakwater was 16 metres and 20 metres off Weol Pyeong Beach. And for those of us that don’t like filling our luggage with dive gear, Big Blue 33 will rent out what you need to go diving.

There was yet another far away typhoon starting to affect the sea conditions, so feeling lucky to have had two successful days of diving, I moved onto Busan, South Korea’s second city. After the relaxing atmosphere of Seogwipo, being back in a 24/7 metropolis was a bit of a shock! Also my planning for this leg of the trip left a lot to be desired as it turned out that my accommodation was an hour and a half away from the dive site, Taejungdae Beach. As I didn’t have a car, this was to be an hour and a half of on public transport! So having unexpectedly added to my life experiences the joys of lugging full dive gear and a camera through an underground rail network, I met up with my dive guide, Stacie, for another day’s diving. For the record, Busan Seaworld Dive Center do rent out dive gear – I just like to use my own!

South Korea

Taejungdae Beach was another cobblestone beach, but this time crammed with tarpaulin restaurants offering every kind of barbecued local seafood. All had two blue hoses going in and out of the sea, which served to keep their live ingredients fresh and for my dive guide and I, it helped with our navigation!

Stacie had already advised me that Busan’s diving wouldn’t be a good as Jejudo’s, so my expectations had been suitably lowered; but with 4 metres visibility, I found it to be very enjoyable! Perhaps I’ve been diving exclusively in the UK and Ireland for too long, but 4 metres visibility is more than plenty for me to enjoy myself underwater, especially when it was a glorious sunny day and the water a lovely 24 degrees.

South Korea

The deepest we went to was 12 metres. The seabed was mainly covered with boulders and the sealife was noticeably different to Jejudo – there were plenty of fish, although less of the tropical variety. What stood out for me here were the numerous feather stars growing in between the crevices. Among them were crabs, gobies, scorpion fish and on the second dive, I spotted another nudibranch, although it wasn’t of the gigantic variety, but a tiny Bouphonia. My dive guide was more surprised than I was by the Bouphonia, but just as excited.

South Korea

In keeping with tradition, we celebrated by eating more delicious Korean cuisine, although we decided against a seaside barbecue. I love seafood, but having just enjoyed diving and photographing the local sealife, I wasn’t quite ready to eat it straight away. So we filled up this time on meelmyun (spicy cold noodles). Unfortunately for the final day’s diving Mother Nature intervened again with another typhoon off the Philippines (later I felt guilty about a complaining about a ruined day’s diving when in the Philippines the situation was probably a bit more serious). I was told that I had been unlucky with the weather as typhoons generally only affect South Korea much later in the year. To console myself, I finally brought myself round to eating some of the local catch in the form of hwedobbab, Korean sashimi served with rice, vegetables, dried seaweed and a generous dollop of chilli paste, before heading back to see more of my family in Seoul.

Overall, I had a great time. I loved the diving that Mother Nature allowed me to do and I had a lot of fun eating Korean food, drinking Korean soju (in moderation whilst diving of course), and meeting new people whilst enjoying the rich culture Korea has to offer. I think another ‘family’ visit is in store in the near future!

Yo-Han Cha is a member of the Northern Underwater Photography Group and started taking underwater photos with a Canon Ixus 980 IS before upgrading to an Olympus OM-D EM-5 two years ago. He has a BSc (Hons) in Biochemistry and works as a Network Engineer for a telecoms company, neither of which is relevant to his underwater photography. Well, the job pays for the kit and trips, so it’s kind of relevant. He learned to dive whilst backpacking in Australia as he thought it would be the best way to see the Great Barrier Reef, and when he got back, started diving in the UK as he wanted to dive with seals. He is a member of both Bolton Area Divers (PADI) and Manchester University Sub Aqua Club (BSAC) as he finds it difficult to turn down diving opportunities. He loves going diving and is usually at his happiest when either taking photographs of nudibranchs or of seals. He prefers scenic diving but concedes that wrecks make lovely artificial reefs.

Exhibition: Protecting UNESCO Marine World Heritage through scientific research



From now until 30 October, the photo exhibition “Protecting UNESCO Marine World Heritage through scientific research” features 21 photographs at UNESCO Headquarters, Paris, as well as a digital edition.

Exceptional photographs highlight how innovative marine experts and scientists take the pulse of the ocean by exploring ecosystems, studying the movement of species, or revealing the hidden biodiversity of coral reefs. Scientific discoveries are more important than ever for the protection and sustainable conservation of our Marine World Heritage. This memorable exhibition comes ahead of the launch, in 2021, of the United Nations Decade of Ocean Science for Sustainable Development (“Ocean Decade”). The exhibition was jointly developed by UNESCO and the Principality of Monaco.

The 50 marine sites inscribed on the UNESCO World Heritage List, distributed across 37 countries, include a wide variety of habitats as well as rare marine life still largely unknown. Renowned for their unmatched beauty and emblematic biodiversity, these exceptional ecosystems play a leading role in the field of marine conservation. Through scientific field research and innovation, concrete actions to foster global preservation of the ocean are being implemented locally in these unique natural sites all over the world. They are true symbols of hope in a changing ocean.

Since 2017, the Principality of Monaco supports UNESCO to strengthen conservation and scientific understanding of the marine sites inscribed on the World Heritage List. This strategic partnership allows local management teams to benefit from the results obtained during the scientific missions of Monaco Explorations. The partnership also draws international attention to the conservation challenges facing the world’s most iconic ocean sites.

The exhibition invites viewers to take a passionate dive into the heart of the scientific missions led by Monaco Explorations in four marine World Heritage sites: Tubbataha Reefs Natural Park (Philippines), Malpelo Fauna and Flora Sanctuary (Colombia), Rock Islands Southern Lagoon (Palau), and the Lagoons of New Caledonia: Reef Diversity and Associated Ecosystems (France). It is also an opportunity to discover the work of a megafauna census; the study of the resilience of coral reefs and their adaptation in a changing climate; the exploration of the deep sea; and the monitoring of large marine predators through satellite data.

Deptherapy returns to its Roots – Part 7



Join Richard Cullen from Deptherapy for the final part of his Blog about the charity’s recent expedition to Roots Red Sea, El Quseir, Egypt.

Deptherapy expeditions do not just magically happen, they need planning and they need funding.  This expedition was funded by our long-term partners the Veterans’ Foundation.  The funding is part of a grant they awarded us for programmes this year, which were then put on hold because of COVID.

All charities in the Armed Forces’ Sector are struggling for funds. Deptherapy desperately needs support going forward and every penny counts.

We know what we do works and at the end of this blog you will find details of the research studies into Deptherapy’s programmes and how they impact on the lives of our beneficiaries.  This includes details that are hot off the press about the latest study that reports that what we offer through scuba diving and 24/7 support has benefits beyond those found in other sporting rehabilitation programmes.

Well tomorrow we fly home, late in the evening with the journey home for some of the guys who live up North taking around 15 hours after leaving Roots.

We want to make the most of today but with the tide running we are not going to be able to dive until later this morning which means only two dives today.

Oatsie and Swars about to start their sidemount dives

Things, however are really busy over at the dive centre with Swars and Oatsie putting their sidemount kit together for their training dives with Steve Rattle leading to their RAID sidemount qualification.  It has been nice to be able to offer the guys this extra training, given the amount of work they have put in this week.  They have needed to get through their theory quickly but given the RADI online learning system this has not been too arduous.

Steve came diving with us yesterday to get some more photos and was really amazed at the progress that Corey had made. He was quite open in his praise, as in his view Corey has gone from a non-diver to being a very competent OW diver capable of diving, unsupervised, with a buddy.  Praise indeed.

Other than the sidemount course we are diving as a group today: Corey, Keiron, Michael, Moudi and me. Corey has been given some tasks – SMB deployment on both dives and the afternoon dive will be a ‘naturalist dive’.  Guy Henderson has set Corey a task: ‘to identify three species of fish and record the time into the dive and the depth at which each one was spotted’.  Guy runs Marine Biology courses on the reef and knows where the fish are to be found, how long into the dive, and at what time.

The two Toms are getting put through their paces. They have walked their cylinders down to the entry point, but Steve sends them back to the dive centre to collect other kit they should have brought with them.

Our general dive goes well and the sidemount guys appear from their sidemount dive some 90 minutes after dipping their heads under the water.

Corey enjoying being a RAID OW20 Diver

Lots of bubbly chat at lunchtime, a group of really happy divers. Corey really has benefited from the week and over lunch thanked the team for making him a diver. He has very quickly become part of the family and after returning home he published an amazing post on Facebook about his experience.  Corey really gets Deptherapy and had soon realised that we see past mental and physical injuries and see the person inside and work with that person.  He also realised that we want beneficiaries to see their fellow beneficiaries in the same light.  He knows he now has another ‘family’ – a family of brothers in arms who have two things in common, they served their country and they have suffered life changing injuries or illnesses.

Back into the water for the afternoon dive and Corey identifies the fish and records the details on a slate.  The two Tom’s complete their second dive and qualify as RAID Sidemount Divers. Great!

Kit packed away and it is time to return to the camp for a few well-earned last night drinks.

I am often asked why we use Roots as our exclusive base for diving. I have mentioned before that it offers us an ideal retreat, away from the hustle and bustle of everyday life. We are secluded and there are no distractions such as late-night bars etc.

Roots Accessible Room

The second reason is the amazing welcome we receive from Steve, Clare, Moudi and the team.  We have been going to Roots since 2014 and many of the staff have become good friends, they understand our needs and are the friendliest people you could ever wish to meet.

The third reason is the huge investment Steve and Clare have made in making the resort and dive centre accessible for those with physical injuries including those who need to use wheelchairs.  All our beneficiaries can enjoy Roots and, in fact, love it here.  The reef is perfect for us and in non-COVID times we can travel to the Salem Express and other dive sites to enjoy more of the Red Sea experience.

Accessible toilet on the Roots beach

After discussions with the team I was very proud to be able to tell Corey that his progress had been such that we were inviting him on the Armed Forces Covenant Fund Trust sponsored two-week Marine Biology Course at Roots in June 2021. There is lots of homework to undertake under the guidance of Dr Debbie McNeill of Open Oceans and Corey will be sent the Red Sea Guide which is the basis for study.

While on that programme, Corey with fellow beneficiary Dale Mallin, will complete his RAID Advanced 35 course.  This all builds to a 10-day Red Sea liveaboard in 2022, onboard Roots’ new boat Big Blue where 18 beneficiaries will compare the coral and aquatic life on the wrecks of the SS Thistlegorm and the less known SS Turkia that is to be found in the Gulf of Suez and is rarely dived.

Paul Rose, our Vice President, is supporting the programme and is seeking the support of the UN and the Royal Geographical Society. A comprehensive report will be submitted to our partners in the project and to the Egyptian Authorities.

Last night and chill

What we do works:

In recent years there have been three academic studies into our work:

2018 – A study by a team from the University of Sheffield Medical School.

2019 – A study by The Centre of Trauma at Nottingham University.

Both these studies reported very positively on Deptherapy’s work both underwater but also in terms of the provision of 24/7 support.

The following is from our press release which was issued on 26th October:

‘A new study into Scuba Diving Rehabilitation Charity Deptherapy’s approach to supporting Armed Forces veterans with psychological injuries such as Post-traumatic Stress Disorder (PTSD) through the medium of scuba diving has been carried out by Petra Walker in conjunction with Hanna Kampman of the Posttraumatic Growth Research Unit at the University of East London.

This study, which used Interpretive Phenomenological Analysis (IPA), demonstrates that scuba diving has rehabilitation benefits beyond those found in other forms of sporting rehabilitation exercise. IPA is a qualitative methodology that examines the experiences of participants and has been used in previous studies of Posttraumatic Growth (PTG) in para-athletes.

Petra is an experienced diver herself and was exploring the wellbeing aspects of scuba diving as part of her Masters in Applied Positive Psychology and Coaching Psychology when she came across a previous study on Deptherapy. Past studies have mainly focused on the medical aspects of diving, so the opportunity to examine the mental health side of rehabilitative scuba diving was impossible to ignore. The full study is currently embargoed until it is published at a future date in an academic journal, but it follows similar academic research into the work of Deptherapy by the University of Sheffield Medical School (2018) and the University of Nottingham (2019).’

This is amazing news and sets us apart from other sporting rehabilitation programmes.

We are currently working with our VP Richard Castle who is a Consultant Psychologist and our Dive Medicine Advisor Mark Downs to identify further areas of psychological and physical dive related research.

We end the week on a happy note.  A young man who has learned to dive properly with a RAID OW 20 certification, a new RAID Master Rescue Diver, two new RAID Sidemount Divers, 5 new RAID O2 Providers, many assessments for our DMs but most of all a week of learning, of making new friendships, renewing old friendships, and building on our family ethos.

Until we meet again…

For us, Deptherapy is a journey, a journey that continues to push boundaries in the use of scuba diving in the rehabilitation of those suffering life changing mental and/or physical challenges.  On our journey we want to change the way the scuba diving industry views diving for those with disabilities.

In the new year, we will be launching, with our diver training agency partners RAID, a new and exciting adaptive teaching programme that will offer diving to the disabled community. We can’t wait to share it with you!
