Extraordinary underwater living project re-visited

Bournemouth and Poole Sub Aqua Club in the UK celebrated their 60th anniversary by recounting the inspirational story of a former member who made history by living underwater for an entire week.

Back in September 1965, Colin Irwin, who was then aged 19 and science officer for the club, spent seven days on the seabed of Plymouth Sound in a specially made steel cylinder to investigate long-term survival in an underwater habitat.

The Glaucus Project – named after a Greek sea god – was a tremendous success and still has its place in the Guinness Book of Records.

Colin gave a gripping account of his adventure to members of the club when they gathered to mark its 60th anniversary at a special event in the Harbour View Suite of the RNLI College in Poole on Saturday 29th March.

Inspired by similar experiments carried out in the early 1960s by legendary French diver Jacques Cousteau, he decided to set up a project to put an undersea habitat in place and occupy it for a week along with fellow club member John Heath, then 21.

Adrian King, who has been a member of the club since 1976 and served as its chairman for the past six years, said: “Even by modern standards this was a hugely ambitious project which at the time – and indeed since – had only been attempted by a few majorly funded operations such as Jacques Cousteau and the likes of the America Sea Lab.

“A sub-committee was formed to raise the £1,000 needed to finance the project. The father of one of the members owned a local boatyard and they built the steel cylinder for the project from scratch. Weighing two tons, it was 3 .7 metres long and 2.1 metres in diameter, standing on legs and ballasted by weight in a tray beneath it.

“Entry was made via a tube on the underside which was open to the water. Pressure inside would therefore be the same as the surrounding water, resulting in the divers being at pressure for the duration of the project.

“The main cylinder was equipped with two compartments, a main living area and a separate toilet compartment.

“The two young men kept in touch with the surface via an old ex-army wind up telephone and there was also a small CCTV camera to allow the condition of the crew to be monitored constantly from above.

“The cylinder was towed into place by a tug then lowered 35 feet or 11 metres to the seabed near the Breakwater Fort and marked by a buoy on the surface.”

Adrian added: “Where this one differed significantly from the Cousteau and American experiments was that the Glaucus Project cylinder was not linked to the surface by an airline but had its own artificially maintained air environment with a chemical `scrubber’ to remove the carbon dioxide.

“It was for this reason and the length of time the two men spent underwater that Glaucus still has a place in the Guinness Book of Records.

“The cylinder was far from comfortable to be in with the temperature being about 16 degrees. In addition the near 100% humidity caused by the open entrance meant that condensation was colossal and keeping anything dry became almost impossible. Food and drinks were sent down to them in army field pressure cookers.

“Despite these difficult conditions Colin and John continued with the project and even ventured from the cylinder into the surrounding waters to conduct a number of surveys aimed at proving the ability of divers to both live and work at depth.”

At the end of seven days, attempts to slowly bring the cylinder to the surface were abandoned due to buoyancy problems and the two crew members eventually made their way to the surface wearing scuba gear.

Colin Irwin, who now lives in the Liverpool area, has enjoyed a varied life of adventure including working for National Geographic magazine and sailing on a yacht through the North West Passage of Canada.

Now aged 68, he is a Research Fellow in the Department of Politics at the University of Liverpool and in the Institute of Governance at Queen’s University Belfast.

Colin said: “Although it was nearly 50 years ago I still clearly remember the time John and I spent down in the cylinder. In fact, I still have the daily log for the project.

“We had heard about the Cousteau experiments and didn’t want it to be something that was just done by the French, so we thought we would do our own experiment.

“What I recall most about our time in the cylinder is that it was very cold and damp. However, we did have our food sent down in an army thermos.

“After we had been down there for a couple of days a really ferocious gale blew up on the surface but luckily it didn’t affect us too much and the project was able to continue.

“John and I did some experiments in artificial atmosphere while we were down there. We raised the oxygen level to a point where we wouldn’t get the `bends’ when we came up and I think this must have worked because we didn’t get them.”

The Glaucus cylinder is still underwater not far from its original site. It is dived regularly and the club now has a project to fix a plaque to the structure marking the achievement of 49 years ago.

christmas

SCUBAPRO, the world’s premier manufacturer of high-quality scuba diving equipment, introduces its second generation Luna 2.0, an easy-to-read, intuitive dive computer loaded with easy-to-use features and available in two versions, the Luna 2.0 and Luna 2.0 AI with wireless air integration.

Designed for new and casual recreational divers, the low-profile Luna 2.0 sits comfortably on the wrist. Its oil-filled plastic housing helps ensure reliable performance to depths of 120 meters. A large widescreen display features a high-contrast black and white matrix-segment LCD with full-sized characters for easy reading in all dive conditions. An intuitive menu and simple two-button interface lets the diver navigate the system with ease, aided by clearly marked screen prompts. The LUNA 2.0 offers two algorithms – Predictive Multi-Gas Bühlmann ZH-L16 ADT MB PMG or ZH-L16 + GF PURE, plus 21-50% nitrox compatibility and three selectable gasses for open circuit diving. Three dive modes are available – Scuba, Apnea and Gauge – to suit a range of diving activities.

The Luna 2.0 AI (air integrated) offers the same easy-to-use features and functions as the standard Luna 2.0 plus adds wireless air integration. This not only enables to easily monitor ythe tank pressure, it also provides true remaining bottom time (RBT) and allows the air consumption to be factored into the decompression calculation. Also available with the Luna 2.0 AI is an optional integrated heart rate monitor that lets visually track the heart rate and skin temperature to help staying in the personal target zone.

Both Luna 2.0 models include personalized dive management functions like PDIS (Profile Dependent Intermediate Stops) which calculates an intermediate stop based on N2 loading, current and previous dives and breathing mixes, and Microbubble levels that give the option to adjust the level of conservatism in the algorithm to match the individual experience level, age and physical conditioning for a more enjoyable dive.

The soft silicone arm strap offers a comfortable fit on the wrist, plus bungee mounts on the corners of the housing allow for alternate attachment methods. A Bluetooth Low Energy interface enables the download of the dive data to any iOS or Android device or PC/Mac (firmware can be user-updated), and the CR2450 battery is rated for up to two years or 300 dives.
