Last week our very own Ray Cramer added a very interesting lecture on Bathymetry to the ongoing series of lockdown lectures presented by BSAC.
For those of you that don’t know, bathymetry is the measurement of the depth of water in lakes, rivers or seas. Ray’s lecture covered how this information is collected, used and how it can be of use to divers.
Ray went on to show where to access some of the latest survey data and which software to use to get the best out of it. A sample image here showing the wreck of the Mongolian.
The whole lecture, along with many others are available to watch via the special interest section of the BSAC online learning hub. The website lists up and coming sessions along with a library of past lectures and training sessions.
With the club being shutdown at present because of Covid 19 our training team have taken to the internet to provide lectures via Zoom video conferencing for all who are interested. So far they have successfully run through all the Ocean Diver and Sports Diver lectures as well as Practical Rescue Management and Accelerated Decompression SDC’s with the Twin Set SDC in progress. Boat Handling will be next with other SDC’s are being assessed to see if they can be delivered via zoom.
The club has also been holding weekly zoom club nights and plans are underway for some diving talks and a quiz night.
Anyone wanting further information on club training sessions or talks should check out the club Facebook page or contact the Training Officer.

Alistair Reynolds ran another excellent, and well attended Gas Blending SDC last weekend, helped by Steve McElroy, Terry Maloney and Alan Jones.
The course started on Saturday morning with a series of lectures given by the team on the principles of blending Nitrox and Mixed Gases as well how to use the club blending equipment and safety precautions.
This was followed in the afternoon by a demonstration of Nitrox blending and a number of practical sessions to ensure everyone knew how to use the blending tables, applications and could safely mix different Nitrox blends.
Some of the students were only interested in blending Nitrox at present so chose to finish the course on the Saturday evening. The rest of us were split into two groups to return for one of two sessions on the Sunday.
On Sunday we were given a masterclass in blending Trimix by Steve then given a series of blends to try to mix ourselves working from the blending Trimix tables. A tricky and time consuming process.
Steve got to demonstrate an example of gas layering when adding helium to an existing mix, with a blend of 6/84 showing on the analyser after mixing! After rolling the cylinder on the floor for a minute this changed to a more expected 18/45.
Anyway, after an interesting couple of hours with hands on the equipment everyone seemed comfortable with the process and now ready to get out there and use it to dive….. when we’ve saved up enough for the Helium.
A big thanks to Steve, Terry, Alan and especially Alistair for giving up another of their weekends to pass on their knowledge. It is really appreciated.
This club night Chris Woods again ran the excellent AED course for first timers and as a refresher for those members who had done it before. This is a course with lots of practicals and plenty of opportunity for everyone to use the clubs training equipment and dummies to practice this life saving skill.
AEDs are getting to be more and more common and can be found in many public places. They are a valuable add-on to BLS/CPR and this course teaches their use and promotes the confidence to potentially save a life!
Another very enjoyable course run by Chris Woods this weekend with the help of Garry Bolland. The practicals in this course are always fun and those from this course were no exception. Plenty of practice tending to a variety of symptoms using anything to hand.
Great turn out again for this SDC, with lots of members having their first go as well as plenty returning as a refresher.
The BSAC First Aid for Divers SDC is a one-day course that teaches the basics of non-resuscitation first aid likely to be needed in the diving environment. There is lots of practice on the course giving you the confidence to give first aid in a real emergency. It includes making use of the resources likely to be available at the time including improvisation of dressings and splints using materials and equipment commonly found at the dive site or in a boat. If you already have first aid training, this course is a quick and easy way to ‘practice, practice, practice’ your skills, while learning the best way to apply them in diving.
Contact Chris Woods for details on further courses.
Another successful Oxygen Admin SDC was run by Chris Woods this weekend, ably assisted by Garry Bolland. The classroom was full with plenty of club members doing the course for the first time as well as a number returning for a refresher.
The course Chris runs is heavily biased towards practical sessions giving everyone plenty of opportunity to select the right equipment for the situation as well as to assemble and use the kit correctly in a variety of simulated scenarios.
Although the course has a serious side everyone enjoyed a fun day practicing with both the club kit as well as Chris’s own personal kit.
A successful day was rounded off with everyone passing the exam at the end of the course. Good result all round.
The BSAC Oxygen Administration SDC has a mix of classroom-based and practical lessons, teaching: • Basic life support • Use of the pocket mask • Oxygen and diving incidents and how they benefit from oxygen • Casualty assessment • The use of oxygen administration equipment
Contact Chris Woods if you are interested in any future courses.
Chartwork and Position Fixing SDC Saturday 11th and Sunday 12th May 2019
By popular demand there will be another running of the BSAC Chartwork and Position Fixing SDC in May this year. This course builds on the Boat Handling SDC and helps towards the Diver / Coxwain assessment.
The course involves a number of classroom lectures and practical exercises followed by time out on the river putting it all to good use.
There is an entry sheet on the notice board if you wish to take part. A £25 deposit will be needed before the end of January.
A group of new Branch 5 sports divers went off to Stoney Cove in Leicestershire last weekend for two days of progression diving under the expert guidance of Alan Jones.
With the help of Martin Campbell, John Dunne and Robbie Edwards all five were put through their paces. The water was cold and although the visibility wasn’t too bad down to about 25m it was pretty poor at the bottom. But everyone coped and by the end of the weekend all had been signed off to 35m.
Accommodation on Saturday evening was at the Mill on the Soar. An excellent inn less than a mile from the quarry with great rooms with breakfast at a very reasonable price. Everyone enjoyed an extended evening meal, a few well earned drinks and a lot of laughs.
Really enjoyable weekend was had by all even if the water was only 6 degrees. Certainly showed who had the best undersuits !
Organiser: John Rice Date: 19:30 – 21:30 Thursday 10th January
Another opportunity to learn to how to safely fill your own cylinders, and assist others with their tanks too. Alistair Reynolds will be running the course over a few weeks with the theory sessions delivered in the clubhouse, and the practical sessions in the compressor room/boathouse.
The theory side of this SDC has now been completed and practical sessions are taking place over the next few weeks.
Anyone interested in this course should contact Chris Woods to check when it will be run again.
Chartwork and Position Fixing SDC Saturday 15th and Sunday 16th December 2018
This weekends Chartwork and Position Fixing SDC was a fantastic success. All those who attended really enjoyed the course put together by Gary Bolland and Geoff Oldfield.
Along with Gary and Geoff, Alan Jones, Alistair Reynolds, Stuart Langley, and Tony Fitz were also on hand to give lectures on Nautical Charts, Position Fixing, Tides, Locating Dive Sites and Passage Planning.
As well as the lectures there were plenty of practical exercises Gary had put together to put the theory into practice and building towards a usable voyage plan.
Geoff also gave us a demonstration of an amazing piece of software from Neptune Navigation, which for just over £100 gives access to all the UK charts, tides and many wreck sites details. Click here for more details.
Unfortunately the weather prevented us from taking the boats out on the river for the water based part of the course so this has been put off until Sunday 7th April.
Everyone who attended the course would like to thank all the instructors for giving up their weekend and passing on their extensive knowledge of all the subjects covered. Its great to have this about of experience available to club members.
