Scuba Diving at Silfra Fissure

Scuba Diving at Silfra Fissure

One of the adventures I looked forward to most when visiting Iceland last year was the opportunity to dive in Silfra in the Thingvellir National Park.

There are two exciting draw-cards to diving at Silfra—the famously clear water and the fact that the dive occurs in the fissure between the continental plates of Europe and North America.

We booked on with DIVE.IS, and completed our dive medicals and equipment sizing online, well before we left Australia. DIVE.IS’ system and customer service were seamless and responsive.

We were picked up from our hotel in Reykjavik at about 7:15am and then travelled to Thingvellir National Park for our dive.

As stated, Silfra Fissure lies on the tectonic fissure between the North American and European continental shelves. Above the surface the fissure is a couple of kilometres wide, but underwater you can reach out and touch both continents simultaneously.

The visibility here was nothing short of amazing — it was at least 50m, but the range of vis was limited by the rock shelves and formations in the distance. The water is glacier fed water filtered through the rocks of decades and centuries.

The dive entered at a set of metal stairs onto a metal platform where one group enters at a time, does their buoyancy checks before descending to 5-6m. You swim along, coming back up to the top of a wall in <1m ,before re-descending to a maximum of 18m (we got to about 15m). After a time you do a left turn into a lagoon, with a separate exit platform followed by a short walk to the carpark.

The water was, of course, very cold. While the dive leader (Tanya) stated that the range was 2—4C, my (borrowed) Oceanic OC1 computer showed that the temp got down to <1C. The rental drysuits (Bear hyper crushed neoprene) and undergarments did a perfect job — no leaks. We also wore mitts and a hood, and although these were not sealed they did an adequate job of keeping relatively warm — although the hands did get so cold that you lost most dexterity.

No life to speak of in the fissure — the reason to dive the site is for the site itself, with its spectacular rock formations and crystal clear water. The guide did mention that there are fish in the lake Silfra empties into, but they don’t come back up in into fissure.

DIVE.IS1 is a professional dive operator, with good equipment, facilities at the dive site and very good leaders. Group sizes were small (3:1 max), and there was a very welcome hot chocolate waiting back in the carpark.

The dive itself was conducted very professionally, following strict safety protocols. There was oxygen at both the entry and exit points, and additional staff were on hand to assist with gearing up and de-kitting, and to assist during entries and exits.

With over 1,500 scuba dives to my name, I have had the opportunity to dive in many very special places, but the experience at Silfra will certainly go down as one of my top five dives to date.

An outstanding dive.

  1. As I write this the world is in the midst of the COVID-19 pandemic. DIVE.IS has suspended tours until things improve, and are currently intending on resuming limited operations in early May. I wish the DIVE.IS team all the best, and look forward to diving with them again in the future.

I was surprised today to see blog post from DeeperBlue on Diving Papua New Guinea, featuring one of my images from a trip my wife and I made there in 2006.

We love PNG, and have dived at Kavieng, Kimbe Bay (Walindi), Milne Bay (Tawali) and Tufi. These are all amazing diving locations, and I am happy to see one of my images being used to promote diving in this part of the world.

With that said, a bit of advance notice and link back would have been nice!

PADI Announces Commitment to Rebreather Training

PADI Announces Commitment to Rebreather Training

PADI, the world’s largest diver training organisation has announced that PADI will be launching rebreather training for closed circuit rebreathers (CCRs) in 2011.

Mark Caney, Director, Rebreather Technologies in PADI’s Technical Diving Division, today announced that PADI is planning to introduce its first rebreather courses to include closed circuit rebreathers next year.

PADI has had limited training for semiclosed rebreathers for some time, but the step into the launch of training for CCRs shows a recognition that these products are now ready for playing an important role, if not in the mainstream, on the edges of the mainstream.

Caney said that PADI will produce a range of rebreather courses covering the needs of recreational and technical divers, and that the first courses will become available next year. They will be supported by the usual high quality educational materials that PADI is well-known for.


No announcement has been made of which rebreathers will be initially supported, but I woud guess that the Hollis Prism 2 and the Poseidon Discovery units that have recently been, or about to be, released would be strong candidates, as they are well supported units that support a range of diving from recreational to technical.

Rebreathers, and rebreather training, are not new. Until now, however, they have been rather niche due to their cost and complexity, as well as the limited support for rebreather supplies in many parts of the world. With PADI coming on board to support CCRs with its high quality training, I suspect that the tipping point is approaching when they become more mainstream.

With that said, I also don’t think CCRs will be replacing traditional open circuit scuba any time soon. Instead they will become a great option for some divers and some diving applications.
