Ang Thong National Park Expedition

We just returned from a great cave diving expedition to Ang Thong National Park in the Gulf ofThailand. The aim was to locate the cave that feed the saltwater lagoon on Koh Thali Nai, this saltwater lagoon is in the center of the island and surrounded by sheer cliffs. The lagoon is a saltwater cenote and fed by an underground cave to the sea.

 We found this map by some French cave explorers locating the entrance on the eastern side of the island. The main problem would

be locating the cave and predicting the flow in the cave, as at sometimes the cave would turn into a syphon, pushing you into the cave making it difficult or impossible to exit if the cave is impassable. Syphonic conditions are also dangerous as you need more gas to exit and sediment stirred up will washed into the cave with you.

We quickly located the seaward side entrance not far from the beach, with a high flow running out of the cave just one hour before low tide, as the lake was emptying into the sea. The cave was wide nearly 5 metres across but only 70 cm high making sidemount diving the only choice. After a primary tie off on the surface we descended to the entrance. With 3-4 knots current flowing out of the cave, it was impossible to swim against. Tim Lawrence and Myself had to push and pull ourselves along through the restriction. Each metre of penetration was hard work wriggling through the restrictions and pulling against the current. Fish and rocks came hurtling past, and any sand we disturbed was quickly swept away.
After 20 minutes of struggling against the current we decided to exit, and return the next day at a different state of tide.

On the following day we dived three hours after high tide, hoping that this would be the slackest time to dive. Flow out of the cave

however was not reduced; we managed to lay around 50 metres of new cave line into the cave and must have been close to the exit but again were turned around by the current. We walked over to the lakeward side and quickly located the entrance by following the flow out of the lake.

Advanced Course at Sail Rock

By , 12 October, 2011, No Comment

This week I was fortunate enough to take an advanced course to Sail Rock which is widely recognised as one of the best dive sites in South East Asia. It was a fantastic day all round, not only did we experience great conditions but I was with an excellent group of students which enabled us to have a couple of long, relaxed and spectacular dives. Sail Rock, as it sounds, is a great big rock which rises from the ocean floor and breaks the surface about two hours away from Koh Tao.

One of the main features of this dive site is that it has a coral ‘chimney’ which starts at around 6 meters and you dive through it to an opening at about 18 meters deep. It is an ideal site for an advanced course because apart from offering depths of up to 30 meters, it also has an amazing amount and diversity of aquatic life. On our dives this week we saw huge shoals of barracuda, trevally, big eye jacks, queen fish and giant groupers as well as thousands of other smaller species.

Everybody enjoyed the day trip, not least myself and my awesome divemaster Lucy, with cracking weather, great visibility and no waves at all.  All my students, Simon, Nanna, Chris and Adam had an amazing course and all are still diving here at DJL and we are all now looking forward to the next trip to Sail Rock!

C47 Civillian Transport Plane

By , 7 October, 2010, No Comment

Tim, Kris, Marielle and a new trimix student are out technical diving again around Koh Tao, looking to take advantage of the unusually calm weather we’ve got at the momen. We’ll be diving on mild tri-mix to take the edge off at 60m. We will be shooting some video and trying to find out what the cargo was, if any, as we’re having trouble finding out about any of the history of the C47 civillian transport plane.

We will be putting are findings, along with videos on our website www.davyjoneslocker.asia

DJL Explores Angthong Marine Park

DJL Divers at Sailrock

DJL Diving has recently returned from an exploration trip to Angthong National Marine Park. The group of 14 were made up of Divemaster Trainees, Divemasters, Instructors, friends, family and were led by Ali from DJL.

We left early Sunday morning for the first dive at Sail Rock, where we had an amazing time diving with the huge amounts of marine life south-south east of Koh Tao. From there we headed west to the marine park. Despite the long journey spirits were high with excitement of what to find at Angthong and with lots of music and a few beers the time flew by.

We arrived just after dark after some helpful thai fisherman guided us in(as you can imagine there aren’t many lights on Angthong!)

We spent the evening in a small beach resort, had a well deserved meal an spoke of what to expect when the sun rose.

The following morning everyone was up bright and early, ready for some exploring.

After breakfast we checked out the deserted white sandy beaches, photographed the local monkeys, discovered huge caves, climbed the limestone cliffs to amazing viewpoints and looked down over the emerald lake. We then took the DJL boat around the almost inhabited islands and experienced some breath-taking views.

After a busy day in Angthong we headed back north-north east to Koh Tao whilst fishing on route. We had a great sunset dive at shark island to help finish off a successful trip.

DJL Diving will be offering this trip starting January 2011, definitely one not to be missed!

I’d like to thank everyone who came along and helped make this research trip possible and a big thank you to Ali for driving the boat and leading the group!
