The California Academy of Sciences is looking to fill “probably the best Dive Safety Officer position on the planet” (says a CAS scientist).
If you are or know a DSO, here is the full job description.
The Diving Safety Officer (DSO) reports to the Director of Steinhart Aquarium and oversees all Academy staff and volunteer diving.
The DSO must have a broad knowledge base in all aspects of diving and diving technology that spans the reach of the Academy’s dive program, including diving for research and collections in global locations, and diving for maintenance and public programming at the Academy.
The DSO ensures the safety of SCUBA divers and the Steinhart Aquarium’s living collection, both within the facility and in the field, by implementing and enforcing diving protocols and regulations.
The DSO serves as a member of the California Academy of Sciences’ Diving Control Board (DCB), which has authority over all Academy diving.
The DSO shall be an active scientific diver, as defined by the American Academy of Underwater Sciences (AAUS), be a full member of the AAUS and an active underwater instructor certified by an internationally recognized agency.
The DSO supervises 2-3 full-time and on-call staff, a dive intern program, 50-75 volunteer divers, and manages departmental budgets. This is a full-time, salaried, exempt position.
EDUCATION and/or EXPERIENCE:
The ideal candidate will possess a combination of the following education and/or equivalent experience:
- Bachelors degree in biology, marine-sciences or a related field
- Be certified as a SCUBA instructor from an internationally recognized agency with endorsements in rescue and first aid; preferred minimum of 3 years experience as an instructor.
- Be certified as an Oxygen Administration, First Aid and CPR instructor.
- Preferred minimum of 5 years zoo, aquarium and field scientific diving experience.
- At least 2 years supervisory experience, including managing staff and budgets.
- Preferred certification on Hollis Prism2 closed-circuit rebreathers, ideally with mixed-gas diluent and working dives in the 75 to 100 meter depth range.
- Scientific diver training, including collecting, nitrox, rescue-diver, open water and surface-supplied diving.
- Be able to train others on proper techniques, equipment maintenance and operation.
- Proficiency with computer software such as Google apps, Microsoft office, and budget management systems
I first came across TUSA scooters being dived ‘in anger’ (aka used for real) during Divetech’s annual Inner Space rebreather event held in Grand Cayman.
I was happily bimbling along the wreck of the USS Kittiwake when a rebreather diver whizzed past me. For a brief moment I couldn’t work out how he was moving so fast. His hands were full of a quite large camera system and he wasn’t appearing to fin at all. And then I spotted that his legs were almost akimbo. He was sitting on a bright yellow TUSA SAV-7 EVO scooter – rather like someone would straddle a horse – and this was efficiently driving him through the water.
TUSA has just launched the the latest iteration of their diver propulsion vehicle – the TUSA SAV-7 EVO2.
This scooter has a useful depth rating of 70 metres / 230 feet and features the patented ‘Hands-Free Riding Saddle’. If you are not familiar with this DPV, this is a ‘hands free’ scooter. You navigate it by twisting and arching your body accordingly, leaving your hands free to take photographs or check your gauges and computer, hence the seat on both the EVO and EVO2 is quite important. Very loosely it could be compared to a Western saddle. A flange or flat raised pommel (incorporating a lifting handle) is located to the front and the rear of the saddle. Attached to the front plate of the saddle, below the flange, are two wing arms. One on each side of the plate. These are secured in place by a ‘super knob’, basically a large nut. To use the relevant wing, you unscrew the knob and swing the relevant arm out 90 degrees, before screwing home the knob again.
How does this work underwater? Just imagine the diver is lying horizontally face down with the DPV secured between their legs, as if they were sitting astride a bar stool. The wings are reminiscent of pillion foot pegs on a motorbike. However they are longer and there is no physical contact by the diver piloting the DPV, ie they are not lying on them. The wing is a handle for an additional diver to hold onto for towing purposes, or they are a means of attaching equipment to the DPV. Two holes have been cut into each wing, allowing you to clip or karabina off kit to the wing. When not in use, the wing(s) can be retracted and secured in place to provide better steamlining, as they lie on the front of the saddle plate. TUSA state that this DPV is capable of comfortably towing two divers, hence the two wings.
I can see this scooter being quite popular in resorts like the Maldives where the currents are famous (or infamous?) for their strength. Whilst it is possible to mitigate for hard currents by diving at specific tide times, using reef hooks and diving with the current, there are times where you just want to go and look at a particular coral head, or fully explore a wreck, and you cannot get there because you are unable to swim against the hard current, or you do not have the time or gas to do it. TUSA state that by using a DPV you can travel 3 / 4 faster than finning normally. Plus using a diver propulsion vehicle can decrease fatigue and reduce gas consumption therefore allowing the diver to go further and faster in a variety of conditions, extending their time in underwater.
So what has TUSA changed on this model? Three things: speed, range and runtime.
The design of the rotational speed adjustment function has been reviewed to make it quicker and more responsive, and the DPV is now capable of 4.5km / 2.8 mph compared to 4.2km / 2.6mp on the previous model.
TUSA has also substantially increased the range, torque and burn time by exchanging the Lead-acid battery for a high performing, long-lasting Lithium-Ion Battery (complete with an L.E.D Battery Life Indicator). The SAV-7Evo had a range of 4,200 metres / 2.6 miles with a burn time of 80 minutes. The Evo2’s figures are quite impressive. A range of 7,200 metres / 4.5 miles with a burn time of 120 minutes. Available in black.
Here are the specifications:
Speed: 4.5 km / 2.8 mph
Depth Rating: 70 metres / 230 feet

Underwater Explorers in Dorset, England has advised us of an update on a popular Portland wreck.
Following an incident in May, Portland Harbour is taking measures to avoid diving incidents related to the Countess of Erne. The wreck is to be permanently marked with a buoy on the bow. Detailed handouts are also being prepared to give to visiting divers to help reduce in-water accidents.
On 22nd May three divers were swept out of the East Channel as a 90 metre tanker was being piloted in. The divers had apparently failed to find the Countess of Erne and started an ascent. During the ascent they conducted a 5 metre safety stop and ended up drifting through the channel as the tanker with a draft of 5.4 metres was being piloted in. It was only because the pilot boat spotted the divers’ SMB and the tanker was small enough to alter her course, that an incident was avoided. Had this been a larger less maneuverable vessel and the timings been a little different, this may have resulted in a very serious incident.
The look of our traditional high streets has evolved. A number of factors have contributed to our change of shopping habits including out of town retail parks and supermarkets, online shopping and the recession. Innovative councils have sought to reinvigorate the British high street using various mechanisms including adopting the ‘pop-up’ shop.
This trend is popular because it allows companies to market or test products, locations or markets, whilst some seasonal businesses use these temporary shops to reach their customers. A shop will ‘pop up’ in a temporary venue and sell merchandise for just a day, a week or a few weeks.
A Cornwall based diving clothing manufacturer has taken this concept to a new level, or should we say ‘depth’.
Fourth Element has a reputation for doing things a little differently, and they have now given the phrase “just popping down the shop” a whole new meaning!
Fourth Element has just launched the World’s first ‘pop-down’ shop at TEKCamp.2015.
For one week only TEKCampee’s have the opportunity of buying an exclusive t-shirt underwater from a ‘pop down’ shop, suspended at a depth of 6 metres / 19 feet.
All the t-shirts for sale are wrapped up in waterproof packaging!
Technical instructor trainer Martin Robson of Eau2 kindly lent his underwater habitat to Fourth Element for the week.
This ‘pop-down’ shop has been a great way of introducing divers to a habitat.
An underwater habitat is used by cave diving explorers so that they can decompress in relative comfort as exploration decompression times can run for many hours.
The habitat allows the diver(s) to get out of the water (either partially or fully) and dekit, thereby reducing their physical and thermal stress. During these prolonged decompression stop the diver(s) will talk, eat, drink, breath oxygen and write up exploration notes.
The phrase “plan the dive, dive the plan” was coined Hal Watts, founder of PSAI. (He was also the one to name an alternative air source ‘an octopus’, but that’s another story.)
Let’s face it, the fundamentals of dive planning remain the same for all divers, a process that every diver should follow. However, when it comes to recording your proposed plan, what do you do? It can be quite simple data or something far more complex, depending on what level of dive you have planned for.
I wish that ‘Deco-Decals‘ has been in existence in March 1999 during my trimix training. I can vividly remember sitting in the cabin of MV Karin – a Scapa Flow liveaboard – with a roll of masking tape, and very precisely covering my wrist slate with strips of it. Once this was evenly applied I would then carefully draw a specific grid in biro. Finally I would take my time to write out my dive schedule and two bailout tables. It would typically take me about 30 minutes to plan my dive and get my slate ready for a dive. Whilst I found the process quite theraputic, the task was a bit of a time thief, and I would lose chunks of my day complying with best practice in dive planning.
Today there is a better option for both OC and CCR advanced and technical divers to record their proposed dive – along with the various bail out options – thanks to a collaboration between Huw Singer and Brit based Bristol Channel Diving Services. The team designed and developed a range of self-adhesive, ‘traffic light’ colour-coded slate stickers called ‘Deco-Decals’. They should fit pretty much every scuba-diving wrist slate available (Size: 200mm x 118mm).
Green – the dive is going to plan.
Amber – depth or time has been exceed and adjustments should be made, ie next depth, next time.
Red – there is an issue that requires immediate action, ie loss of decompression gas, or bailout is needed.
We all know that colour is absorbed at depth, so what is the point of colour coding each decal? In low light conditions the diver will use a light to read their slate – and in blue water there will be a visual difference, albeit subtle. The significance of the colour coding also makes the students think beyond the immediate dive plan and understand the implications of properly planning for set scenarios, in addition to the original dive plan.
Each Deco-Decal is logically laid out, in an accessible format for training scenarios or every day diving up to 70 metre / 230 feet diving, and is available in both metric and imperial. (There is also a V2 version of Deco-Decal dive planning set which is printed slightly larger, apparently making it easier to read underwater for those with slightly older eyes.)
The green slate has a two useful key way points to prompt you where you need to turn your dive – gas pressure or time. Plus you can see the gas mixtures you are carrying, both back gas and deco gas.
The reusable decals are varnished and durable, and you simply write on them using an ultra-fine tipped waterproof marker. Once you have completed your dive and want to input fresh data, just wipe the decal clean with a ‘Magic Sponge’ / ‘Magic Eraser’ or similar product. After multiple use (10+ dives) you can replace a decal by peeling it off cleanly, leaving little, if any, adhesive residue.
The Undersea & Hyperbaric Medical Society (UHMS) is the primary source of information for diving and hyperbaric medicine physiology worldwide. Last month the UHMS held their annual scientific meeting in Montreal, Canada. During the conference 113 posters and 42 oral presentations were given, including two by researchers from DDRC.
Scuba divers should ensure a high standard of dental health and receive dental checks regularly. Studies have discussed the barodontalgia, and orofacial barotraumas of scuba divers, but few have attempted to observe the broad state of dental health in recreational divers. As part of an ongoing study of the health of UK recreational divers, DDRC attempted to gain an insight into the general dental health of divers and other related problems experienced.
The following day Marguerite St Leger Dowse and Dr Gary Smerdon of DDRC Healthcare presented some preliminary findings from the latest element of the ‘Health of Divers’ project.
Both talks were very well received. In fact Marguerite’s talk went down so well that she won the ‘Associates Award for Excellence in Presentation’ Award.
