Sunday shore dive : 12th October 2014

Another club rhib trip was scheduled for Sunday and by the preceding Wednesday was fully subscribed showing the enthusiasm that has pervaded the club.
As it turned out we did not actually take the boat out due to a few call offs and a technical problem discovered at the last minute. However, three members did decide to make the most of it and go shore diving anyway.

The trip started, after a false start, with Steve and Chris descending on Tara for breakfast as Paul assembled his camera , and , having had a rather tasty sausage sandwich, spicy and succulent, in the luxurious surrounding of their new home, we headed off toward Crianlariach and on to Tyndrum where the venue for the day was settled. After a quick detour via the Isles of Skye hotel to check out the launch for a new a new dive site, we arrived at the Slates in damp but calm weather and unpacked the car.

What a variety of kit came out of the car, singles, twins, and a rebreather and as expected Steve was fully kitted up and waiting for the rest of us as we completed our faff checks. Buddy checks at the water and we were off down to 20m where Paul demonstrated an almost perfect rescue from depth as a drill to complete his Advanced Lifesaver award and become a rescue specialist in doing so! Continuing the dive, we traversed around the reef reaching the point before turning and retracing our steps back to the entry site after over an hour underwater. Quite remarkable was Steve’s ability to come up with a reserve in his 12l on this dive! There was some very nice fish life out today, blennies, rock cod, wrasse and pollack with all the hard surfaces covered is squidgy life.

The light was quite good today and while the water had a distinctly greenish hue to it the Sea Urchins were positively shining.

After a good two hour lunch break we went back in but this time went exploring in the East bay out from the slate sheds. Once out onto the slope beyond the confines of the bay, the dive is rather good. Occasional boulders provide reef habitat from nursery shoals and holes for larger fish such as the large ling that we saw , to hide in. Flat fish, scorpion fist and even if somewhat rarely, skate are seen here. The topography was at it’s best below the 20m mark (low water) at the furthest point in the dive, where small shelves and walls stepped down into the deep. It was here we turned and made our way up-slope finding a glacial slab, polished smooth by ice. A couple of Facelina Botoniensis slowed us down for a while, presenting a wonderful photo-opportunity as they raced across the slab. Above the slab, gravel gave way to sand and kelp and the surface. A rather splendid second dive.

That was it for the day, save to rush back to tea and cakes at Tara’s!

The Lesser Yellowshell : 21st September 2014

Diving with an objective adds a little extra to a days entertainment and so it was that we engaged in a survey for one of the least understood of Scotland’s marine invertebrates. There are many organisations and groups that document sighting of our native marine life and when a rare species is seen many people will go out of their way to visit sites with a view to finding and photographing the organism.

Over the last few years an invasive species, the hard-shelled, yellow back sea slug , also known as the Yellowshell, has gradually increased in abundance around our coastline. While most sighting have been associated with extreme depth or sites requiring a hardboat to access them, more and more often, reports have filtered through that they have been spotted near the shore. This then was our objective, to find and photograph this elusive beastie.

Perth-BSAC is not without some academic expertise when it comes to marine life identification, BSc’s, MSc’s and even a PhD or two abound not withstanding the enormous experience of the lay person with decades of actual diving experience and yet with all our combined knowledge there was perhaps only a handful of people who had reported seeing these animals in the wild and fewer still who actually admitted knowing a few rudimentary facts about their habits. What was known was that these shelled invertebrates were slow moving, usually dragging themselves along the bottom trailing vast amounts a silt, presumably a defensive mechanism to stop themselves becoming prey of the more aggressive scallop baggers. It had also been reported that they had been sighted recently in Loch Leven and so the venue for the search was set.

A crack team of five divers met a local expert at Craft’n’things in Ballachulish for 09:30 opening and after a bacon roll and a coffee, a detailed briefing was delivered on how best , given the combined, or rather lack of knowledge, to approach, photograph and possibly collect a specimen. My copy of the Safe Diving practices booklet on close inspection seemed to be missing any guidelines on this subject but it was possibly included in the appendix marked fictional creatures and dragons.

A short transfer to the site and the first wave, equipped with torches, probes and specimen collection jars was duly dispatched on the initial search, the objective was to confirm the site details, identify any potential dangers involved in specimen collection, identify suitable survey areas and report back to the surface support team, where upon the survey teams would enter the water to photograph and collect a specimen. Soon it became clear, by the surface bubble patterns, that a battle royale was in progress and the second team was dispatched to provide assistance. In went the second team and immediately swan perpendicular to the direction the first team had taken avoiding all contact and enjoying excellent vis and fish life. The first team surfaced on time reporting no sightings but an enjoyable dive around the main reef. Meanwhile the second team, while feeling that they were always very close to a Yellowshell, never actually identified either a silt trail or the animal itself and surfacing an hour later reported drawing a blank. The final team, surveying the reef at a slightly shallower depth, reported finding a silt trail left by a yellow hardback but again did not actually spot the animal. They reported another excellent dive with some very large saithe, pollack and ling as well as the varied squidgy life this reef is well known for.

With all teams on the surface and time for lunch a review of the survey techniques was called for and changes implemented. A slightly different search area was called for and the first wave, wanting to complete the survey data for the primary search area, retraced their steps in reverse to ensure the beastie was not hiding beneath some small overhang. The remaining teams decided the second reef was more likely to be a potential habitat and set off to survey it. Out and back went the first team shortly followed by the last group who at the turn reported a sighting ironically as they passed the other group on the way back. Clearly group two had by this time become despondent and had given up surveying, looking instead for other marine life and fishing weights attached to mono filament which was collected where possible. The sighting was of interest but without corroborative evidence other than some Lochness monster style images taken from a camera, shaken in the excitement of the encounter and we are still not able to confirm the existence of the elusive Yellowshell. Anecdotal evidence provided by the third team seemed to suggest that the animal was a poor free swimmer, tending instead to bump along the bottom creating it’s silt trail. They did report that they would need a larger catch bag to land a specimen.

Well there you have it. Perth-BSAC first attempt at surveying for the Yellowshell, some success and a steep learning curve for all involved. With this experience it is hoped that we will be able to get much more conclusive evidence on future dives and unequivocally demonstrate the existence of this creature on some if not all of our dive sites. Thanks all for coming and supporting this event and I look forward to working with you in future.

(Ed- what a load of rubbish. Of course they exist, I’ll dig out an image from the Sunday Sport that shows one!)

The June DTP at Loch Fyne

It’s a fact of life that the more you put in to something, the more you get out and this was very obvious at this months DTP at Loch Fyne. With the holiday season upon us and with other folk washing their hair Perth_BSAC provided the lion’s share of the instructor and people prepared to muck in and help out. Only fair really as we also took most trainees!

On what can only be described as a fantastic west-coast day with a flat calm sea, warm water and good vis the Perth club had three sessions running. Firstly a drysuit and buoyancy familiarization being led by Chirs and an Ocean diver completing his dive Leader lesson under Steve’s watchful gaze with another buddy pair practicing their navigation and buoyancy within the confines of the bay. One other pair from Dundee were undertaking Sports diver training under Edward Haynes’ watchful gaze.

Leading_a_dive_training

All the hard work was today rewarded with firstly a good session being completed covering drysuits and buoyancy culminating in two exploratory dives where the new skills were put into practice. Steve was set a hard task and asked to teach dive leading to a team consisting of an Ocean Diver and a Dive Leader trainee. By running the Dive leader sessions as examples of best practice our Ocean diver had some of the most comprehensive training for his grade possible. Well done to Steve for his innovative approach, clearly an Advanced Instructor in waiting ! Edward reported varying levels of success with his trainees who struggled with deco stops partly due in part to a poorly fitting drysuit and using skills no longer part of the BSAC syllabus and seldom practiced (never a good idea on an assessment). A greater emphasis will be seen here in upcoming months as BSAC reviews buoyancy skills in training.

All in all a very good event with some good diving and with a diver competing his Ocean Diver practical sessions, a very good result.

South Scotland Regional DTP, Loch Fyne, 8th March 2014

It’s not until you step out of your comfort zone and try something a little different that you really appreciate the effort that other people put in. This month the usual organiser had asked me to stand in and run the event, well how hard could that be? I was about to find out.

Preparations starts in earnest about a week before the event with a trickle of notes coming in from people asking to join and as these increase you start to worry about the number of instructors that you have in the pool to assist. You can count on most but illness and other potential commitments sees you phoning each in turn to get that oh so important commitment to show up and coach trainees. A late surge of interest and finally the ’11th hourists’ and we were set with just enough instructors to cover the variety of skills that had been asked for. Of course on the day it never follows the plan!

This month I am very please to report that Perth-BSAC played a lions share in the days events with two instructors, an assistant diving instructor and an assist Dive manager, all of who were key to the days activities. Well done guys!

Having completed the Welcome speech, site brief and allocated trainees to instructors, it was on to the first lesson. Paul went off to start sports diver training with two trainees from Dundee, Hamish practiced his instructional abilities under the watchful gaze of an NQI and while various other groups went about their lessons I supervised a trainee OWI putting Hadyn and another trainees through a weight check and their first dive in the bay area. After an initial shout for more weight we sank into terrible vis which we had to put up with until, basic drills completed, we were able to move into slightly deeper water (3m) where we found the vis actually improved. The stour was an edge effect and in real terms vis was quite good once you got away from the beach. Conscious of the fact this was a first dive for Haydn we didn’t go far or deep just bimbled, looking at crabs, starfish and the other life that we usually take for granted. We ended up doing a clockwise circuit onto the shallow reef to the right of the bay were much to Haydn’s delight and my intense surprise we found a very large and old, admiralty pattern anchor. Next week we will go back and find the rest of the wreck!

After the break and now with Euan performing the role of Assistant Dive manager things flowed more smoothly and the dive slate no longer languished forlornly neglected on the beach. Paul continued with his trainees who both performed well, another great performance there. Hadyn went for a dive along the inner reef seeing some good life including a superb Polycera nudibranch and coming out with a smile broader than his hood.

Some impressive stats on today’s dives but from a club’s perspective some good training delivered, a couple of lessons signed off, a first open water dive and we found a wreck ! (anchors don’t count – Ed!) Many thanks to all the instructors and helpers who made the day possible. Remember the event runs every 2nd Saturday of the month, looking forward to seeing you in April.

Kintallen Wall, Sunday 2nd March 2014

Having advertised a club trip two divers made it out on Sunday to join a couple friends from Fyne Divers across in Ballachulish. deciding to dive Kentallan Wall over the morning coffee saw us drive the short distance around the coast towards Oban to arrive at an almost full dive site. The view across to Morven here has got to rival any views from a dive site on Mainland Scotland.

The tide was on the flood so a clockwise circuit was decided on and the teams, diving in two loose pairs reported varying degrees of success in finding the edge of the wall. Paul and Chris drifted slowly along the wall at the 25m mark eventually finding the hanging rope and heading for home while Edwards and Claire who were perhaps further West reported rocks, shelves and a mud slope which they followed down to the 30m mark.

A short break in the Hotel for lunch before the second dive. E&C were training which left the second pair free to explore the Northern reef in what turned out to be an interesting dive. Initially over sand and stones where anchor chains and mooring rubbish littered the bay, the bottom sloped onto silty mud with scattered sea-pens while on the return trip the small wall and slabs of the reef provided interest. Some interesting life on this dive which while scattered around more than made up for the flat nature of most of the dive.

Two good dives again today in very reasonable visibility for once though only one type of nudibranch spotted today which was far to small photograph ! (or was it? -Ed)

Sunday shore diving. Loch Leven. 23rd Februry 2014

A couple of hardy souls drove across to the west coast for a shore dive on Sunday through some very wet landscapes. Loch Earn was full and the Glen Falloch was flooded and in spate. Loch Tulla was lapping at the A82 and sheep stranded by the rising water where clustering on small islands waiting to be rescued.

We arrived slightly early and had a look at the Slates dive site and were very pleased to see that it was sheltered from the Southerlies that were sweeping across the loch raising water sprites which flung themselves along the far shore. Retiring to Craft and Things to meet ours guests and friends we were soon enjoying egg rolls and fresh coffee and watching squalls stravage through the glen wreaking havoc while we sheltered in the friendly warmth that the cafe had to offer. With one new member in the team and admin completed it was back to the site to give a short brief and get the first wave in. Edward and Alan and then Hamish and Alistair were in first which gave Chris a chance to work with Claire doing some prep for her upcoming PIE while providing shore cover. The first pair circumvented the main spit while the second pair did a there and back coming back to their entry point, both pair kept good time and stuck to their dive plans ! (Kudos — Ed). Chris and Claire went into the bay to practice AS drills and then extended the dive along the wall, coming back on time and again to plan. Both waves reported exceptionally good visibility with numerous dogfish and a superb Nudibranch (possibly Cadlina laevis)

After a brief surface interval, the afternoon dive saw the same teams back in the water squeezing out a second dive from the mornings tanks taking advantage of a shallower profile. Hamish and buddy went off to explore the reef again getting some impressive perspective of the angle in the excellent visibility while the other teams bumbled around to the right of the bay exploring the large anchors and chains and finding some big glacial slabs. On the way back and in the shallows, the rocks supported colonies of sponges. Of note was a blue rayed limpet reflecting iridescent in a torch beam and of course a couple of nudibranchs, much smaller than the mornings specimen.

That was it, a final warm up in the cafe to chew the cudd before driving back to Perth although we couldn’t resist the opportunity to pay our respects to the badger! Another superb day in the water with great company and a good lesson that you can always get in somewhere if you really want too.

Loch Etive, MV Chana and Loch Creran, Saturday 20th July

With most of the club divers either on the Summer Lewis trip or unable to dive on Saturdays, Kim and I found ourselves joining a few friends loosely associated with Fyne divers or the Regional training attendees.

Meeting everyone in the Green Welly at Tyndrum at 09:00am gave us a leisurely drive across, getting through Loch Earnhead before their highland games started and arriving in plently of time for coffee. We were soon joined by the rest of the team and made our way down to Taynuilt and the first site.

I had dived this site before and was confident that I could find the little wreck again but unfortunately a few of the buoys had been moved and we were left wondering which one gave the start point for finding the wreck. The plan was two waves with the last team providing shore cover. The first team would locate the wreck and mark it with a DSMB, no DSMB no wreck.

And so it was that Kim and I slowily swam out to the buoy and having got our breath back descended the life encrusted chain to the bottom where I almost landed on a large skate. Beautiful fish ! We lined off in a NE direction and found the wreck. Interestingly enough while we could not see the wreck from the chain, the chain was readily apparent from the wreck!

Swimming a couple of time around the wreck, firstly at the level of the sea bed, then at deck level where we deployed and fixed the DSMB and poked our heads into the cabin. We spend a very pleasant 30 minutes enjoying what was a shallow dive at an amazing 15 degrees C, possitively balmy.

Yes ok, there was an initial hickup with my navigation as we swam back to shore on the bottom, picking up the odd pebble (would that be ‘with rough barnacles heavily encrusting a sinking stone’ Ed — hum!) as we did so but when we surfaced we saw our DSMB signal had been received and the other team of divers in the first wave were already on the wreck. The second wave went in as we stripped out of our boil in the bag costumes.

With the divers coming out on cue, we decided to move up to Loch Creran for the second dive via a coffee shop to avail ourselves of icecream, tea and of course the facilities. So we had a leisurely surface interval before moving around to ‘the Steps’ where we had another interesting dive with an amazing variety of loch life including Scorpion fish, ling and the usual gobies and juvenile flat fish and of course one or two Queen scallops.
