Bookshelf: The Annotated Old Fourlegs

The Annotated Old Fourlegs – Mike Bruton (and Prof J.L.B. Smith)

This is a beautifully designed and produced annotated version of Old Fourlegs, J.L.B. Smith’s account of the discovery and positive identification of a living coelacanth in 1938. Wide margins around the original text allow Mike Bruton to bring Old Fourlegs up to date with additional scientific information, as well as photographs, explanations, and other curiosities.

The Annotated Old Fourlegs
The Annotated Old Fourlegs

Old Fourlegs describes the months in 1938-1939 during which Smith confirmed the identity of the coelacanth with the essential assistance of Marjorie Courtenay-Latimer of the East London Museum. Ms Courtenay-Latimer acquired a fish specimen from a trawler captain, and, realising that it was an exceptional find, contacted Smith, an ichthyologist at Rhodes University. A rollercoaster of events – which involved the chartering of a South African Airforce plane and stretched all the way to then-Prime Minister D.F. Malan – was set in motion. Old Fourlegs is a surprisingly emotional, thrilling book by a man deeply invested in his work, and whose world was upended by the discovery of living coelacanths in the waters of the southern Indian Ocean.

It is also a book of its time, and today’s readers will find some parts by turns mystifying, and others offensive. The offensive bits – including lionising D.F. Malan, who, with his government, laid the foundations of the edifice of South Africa’s apartheid legislation – remain so, but Bruton’s annotated version provides context for readers unfamiliar with the history.

The book concludes with an examination of the cultural legacy of the coelacanth, which is disproportionately significant. The fish also has deep and wide links to South Africa and our research and diving community. If you have the appropriate (very deep diving) qualifications, you can dive with them in Jesser Canyon in Sodwana Bay. If you’ve never seen a video of one of these magical animals in motion, I encourage you to hit up youtube. Watch with the sound off for best effect.

Bookshelf: Between the Tides

Between the Tides: In Search of Sea Turtles – George Hughes

I have been late in coming to this book, which was published about five years ago. George Hughes is a world-renowned, South African turtle scientist whose work has done much to ensure protection for sea turtles in the southern Indian Ocean. He was the guest speaker at an event held at the Two Oceans Aquarium to celebrate the release of Yoshi, the loggerhead turtle who spent over 20 years at the aquarium and is now powering along the Namibian coastline in rude health.

Dr Hughes was CEO of the Natal Parks Board and then Ezemvelo KZN Wildlife, but Between the Tides relates his early career as a student looking for turtles along South Africa’s wild north east coast, in places that today support thriving dive and fishing charters. His legacy of turtle research continues.

Turtle surveys were conducted around Madagascar, the Comores, Reunion, the Seychelles, and on the Mozambique coast. The fact that the iSimangaliso Wetland Park now exists, offering a protected and well-regulated breeding environment for three species of turtles (loggerhead, leatherback and green – discovered there in 2014) is thanks to the early and persistent work of Dr Hughes and his colleagues. Turtles were first found nesting on this piece of coast in 1963, when it was still completely wild and mostly neglected by the authorities. In this book Dr Hughes recounts the development of the tagging program that he started, in which over 350,000 hatchlings were flipper tagged and/or marked over a period of 31 years.

Only about two out of every 1,000 hatchlings survive to return to the area in which they hatched, to breed. Female loggerheads are estimated to reach maturity around the age of 36 years, during which time they navigate an ocean of threats. This makes every surviving hatchling incredibly valuable.

The recovery of the number of loggerheads, in particular, has been quite spectacular, with more modest but noticeable gains in the leatherback population. More recently, as technology has allowed it, satellite tagging has shown their movements around the Indian ocean

If you find a baby sea turtle on the beach (this is the time of year when they start washing up), here is what you should do. The most important thing is to keep it dry, and to contact the aquarium as soon as possible.

Dr Hughes also discusses the sustainable use of sea turtles (for example, for food), something which I’d never thought about and which for that reason is fascinating – and very challenging to come at with an open mind, and appreciating the viewpoints of a scientist who has been steeped in turtle research for most of his life.  This is an excellent, proudly South African marine science book, written to be accessible even to those who aren’t turtle fanatics a priori. Highly recommended.

Responsible diving during a drought part 1: Your dive gear

It is no secret that Cape Town is a little low on water. The coastal dive industry, even though we spend a lot of time in the ocean, is actually quite a heavy user of fresh water. Everything thing you learn about taking care of your equipment revolves around the phrase “rinse well with clean water.” Clearly this is not an option in Cape Town at the moment

Dive gear in the driveway
Dive gear in the driveway

So how do you maintain your dive gear and keep it in safe condition during such circumstances? For a dive centre or training facility the volume of gear that needs cleaning can be overwhelming at the end of the day. Here are a few suggestions on how to manage.

No matter how well you de-kit after a shore dive, wet dive gear tends to collect sand. (You can minimise this by using something like the Wetsac, but this isn’t always an option with my students.) I take the gear back into the ocean and rinse it as well as I can in the shallows. This involves several trips as wet dive gear is heavy.

Wetsuits are rugged and don’t too much mind being left salty. They do end up being a little crispy after a while, but the most important, non-negotiable aspect is hygiene. I take a spray bottle with a mixture of Savlon or Dettol and spray the inside of the salty wet suit, then let it dry. Gloves, booties, hoodies and rash vests get the same treatment.

Regulators get a similar treatment, without the disinfectant. I give them an overall light spray with warm water in a spray bottle, with a good spray into the mouth piece. The inflator hose nipple also needs to be rinsed well as this does not handle salt build-up too well and could get stuck during a dive (at best, annoying… at worst, life-threatening).

Cameras, dive computers, torches and compasses do need a little more care, but fortunately are relatively small and have lesser water requirements. I use a narrow, tall bucket and put the bucket in the shower. While showering you can easily catch enough water to cover these items…. Seldom more than a litre is required, and you can leave them to soak.

The biggest challenge is a BCD. Again, it is a tough and rugged piece of gear, but the inflator mechanism does not like salt build up. Using the same bucket of water used for the camera and dive computers, I soak the inflators overnight. I then connect an airline and inflate and deflate the BCD to help flush out the valves behind the inflate/deflate buttons.

Whilst such basic, minimalistic care for your dive gear is not as thorough as that recommended by the manufacturer, it is a method of extending the use of your gear when the availability of fresh water is close to zero. As a rule I prefer to only have two students per class and can effectively wash three sets of gear in less than three litres of water.

It goes without saying that as soon as it rains, you should be collecting that water to give your gear the long, luxurious soak it deserves (and probably needs by that stage)!

Bookshelf: Scuba Professional

Scuba Professional: Insights into Sport Diver Training and Operations – Simon Pridmore

Have you ever wanted to run away and become a scuba instructor? Have you been intoxicated by promises of a lifestyle of tousled, barefoot, beach-based freedom from the rat race? Have you passed your instructor training course and are trying to decide what to do next? Or are you already a dive professional, perhaps looking to solidify your dive business, diversify your income streams, or branch out in the dive industry?

Scuba Professional
Scuba Professional

This is the final, and possibly most important, book in Simon Pridmore’s scuba trilogy (the other two are Scuba Fundamental and Scuba Confidential). Like the other two, it has much to offer – this time, to dive professionals and wannabe dive professionals.

Some of the topics Pridmore discusses are hard truths, such as the fact that becoming a scuba instructor is less about diving than about teaching. A person who doesn’t feel a vocation to teach should probably look for employment elsewhere in the dive industry rather than trying to attain instructor status. He devotes a whole section to teaching issues, many of which will be extremely useful to new instructors looking to move quickly up the learning curve.

An often overlooked feature of the dive industry is that there are many people who make a living from diving, but not by teaching students. Pridmore includes an incredibly helpful chapter in which he interviews several such dive professionals about their jobs, including a gear distributor, a photojournalist, a liveaboard cruise director, and a dive travel specialist. All of these professions include many of the positive aspects of the dive industry, and should provide inspiration for anyone who is keen on the underwater world but doesn’t necessarily feel the urge to teach.

For owners of dive businesses such as dive shops, charters or small training operations, Pridmore has much advice gleaned from running his own dive centre on the island of Guam. Many of his recommendations seem like common sense to anyone who has paid attention to the cycle of boom and bust that seems to characterise the dive industry in some locations, but they are hard-won insights that likely are only obvious after the fact. Unsurprisingly (perhaps?) several relate to safety considerations and gear maintenance. Many of the recommendations Pridmore provides are illustrates with anecdotes describing how he arrived at his viewpoint.

A whole section is devoted to developing a culture of safety in diving, something that featured in Scuba Confidential as well. It can be difficult to discuss dive safety and it seems to me that the industry doesn’t even try. None of the professional member forums I’ve attended, presented by training agency employees with access to incident reports, statistics and trends, has ever addressed dive safety directly. It would be tremendously helpful for instructors and divemasters to know that, for example (I’m making what follows up to make a point) most potential dive accidents happen on dive two of the Open Water course, during mask remove and replace, or during regulator recovery. Because instructors are obliged to report such incidents, training agencies know all about them.

Finally, the future of the dive industry comes under the spotlight, with a discussion of rebreathers (are they the future?) and the likely origin of the next wave of scuba diving students and tourists (Pridmore reckons, China). I was surprisingly moved (for a book about being a dive professional) by the chapter about dive tourism businesses, which concludes with the insistence that the only way a dive business in a remote, exotic location will flourish, is by involving the local community, training them to work in all levels of the business, and spreading a message of conservation that includes the people who live in the paradise in question. This kind of cultural sensitivity has not been the norm in many places, but where it is, the results are special.

Bookshelf: Scuba Confidential

Scuba Confidential: An Insider’s Guide to Becoming a Better Diver – Simon Pridmore

The natural sequel to Scuba Fundamental (though it was written later), this book is aimed at qualified divers who may have reached a plateau with the sport, and want to improve their skills and explore more of what diving has to offer. Author Simon Pridmore does not shy away from subjects such as solo diving, deep diving and technical diving, and offers valuable perspectives from a lifetime in the dive industry.

Scuba Confidential
Scuba Confidential

Pridmore begins with a subject that isn’t discussed enough (because it would supposedly scare away potential new divers): safety. He talks about why divers die, survival strategies, and the essential mental preparation that should come before diving.

Many divers who have passed the first, awkward stage of their careers on scuba seek to improve their skills. Pridmore discusses buoyancy, navigation, and the touchy subject of deco. The following section addresses some of the specialty options available to divers who wish to extend their qualifications: night diving, wreck diving, drift diving, cave diving, ice diving, and technical diving. While you may decide that some of these types of diving are definitely not for you, there is still much to learn from the techniques and thought processes required to do these types of dives safely.

Pridmore also deals extensively with equipment issues, returning to the subject of deploying an SMB, care and use of dive cylinders, mastering your BCD, and dive computers. In many instances, these items of gear are a matter of life and death, and well worth talking about. Narcosis, nitrox, rebreathers and other gas-related subjects round up the sections of the book that pertain to dive safety.

The final chapters deal with dive travel, with a section on liveaboards and a recap of some etiquette, which becomes increasingly important when one is diving with people one doesn’t know.

This book will satisfy a growing diver’s thirst for knowledge, draw attention to areas that need improvement or reflection, and prompt further exploration of dive-related subjects. It’s an excellent gift for the curious diver in your life.

Scuba Fundamental: Start Diving the Right Way – Simon Pridmore

When I first learned how to dive, all I wanted was to find books about scuba diving that were relevant to my stage of knowledge and skill, so that I could learn more (my learning style is by reading). Unfortunately at that time the only books about scuba diving in South Africa that I could find were absolute rubbish (fortunately the situation has improved immeasurably – here’s a quality example). I wish I’d had this book to hand, but it was only published last year, so sorry for me.

Scuba Fundamental
Scuba Fundamental

I read it anyway, with my jaded old eyes. It isn’t specific to South Africa, but it’s written for people who are contemplating learning to dive, who are busy learning, or who are still early in their diving careers. Many of the topics that Simon Pridmore covers are ones that Tony and I tried to deal with in the early days of this blog. He is eminently sensible, and writes from a position of deep, international experience in the dive industry.

How does one choose a dive course? How does one choose a diving instructorWhen shouldn’t one dive? Which certification agency is best? Should a new diver buy their own equipment, and where does one even begin with that? Once qualified, what next? What about diving in cold water and cold weather? How can divers keep safe on the surface? Pridmore also discusses some important elements of dive etiquette such as peeing in your wetsuit, entry techniques (giant strides, backward rolls, and so on), seasickness, dive boat etiquette, behaviour around marine animals, and what to do if your dive buddy surfaces with a giant booger.

If you’re thinking of learning to dive, are busy with your course, have done fewer than 30 dives, or are just seeking some direction in the early stages of your love affair with scuba diving, consider this guide. If you have a friend or family member you’d like to start a conversation with about diving, or would like to buy a dive course for but can’t afford it, this book is an excellent starting point. I found myself agreeing out loud with the author’s observations more times than I can count.

Newsletter: Gremlins

Hi divers

Weekend dive plans

Sunday: shore dives at Long Beach

Monday: boat dives from Simon’s Town, conditions permitting

We had a small gremlin interfere with our newsletter timing yesterday and for this we apologise.

We had decent conditions on Wednesday with dives in the vicinity of Roman Rock. There was a dirty layer on the surface, but underneath there was clear water with visibility of about 12 metres. Today we are taking visitors from Port Elizabeth to explore some local dive sites.

Roman Rock lighthouse on Wednesday

It is the Cape Town Dive Festival this weekend, held at False Bay Yacht Club, so the slipway will be quite busy. I plan for student pool training on Saturday, shore dives at Long Beach on Sunday (working the students hard) and boat launches on Monday (a glorious public holiday).

If you are keen for a shore dive on Sunday or want to be kept in the loop about boat dives on Monday, let me know.

Say yes to 22 new Marine Protected Areas for South Africa

Twenty two new marine protected areas have been proposed for South Africa. The benefits of MPAs are well known, so this is excellent news for the future of our marine environment. The public is invited to comment on the proposal, and as a responsible ocean loving individual, sending an email to comment would be one of the ways you can save the ocean. Read on to find out the details.

Proposed new MPAs for South Africa (existing ones in navy blue)
Proposed new MPAs for South Africa (existing ones in navy blue)

Included in the proposed new Marine Protected Areas are South Africa’s first offshore MPAs. The press release from the Department of Environmental Affairs states that:

Many of these new MPAs aim to protect offshore ecosystems and species, ranging from deep areas along the Namibian border to a more than tenfold expansion of iSimangaliso Wetland Park in the KwaZulu-Natal Province. They include charismatic features, such as, fossilised yellow wood forest at a depth of 120m off Port Nolloth, a deep cold-water coral reef standing 30m high off the seabed near Port Elizabeth and a world famous diving destination where seven shark species aggregate, at Protea Banks in KwaZulu-Natal. These MPAs also include undersea mountains, canyons, sandy plains, deep and shallow muds and diverse gravel habitats with unique fauna.

What good will these MPAs do? According to the press release:

The new MPAs will secure protection of marine habitats like reefs, mangroves and coastal wetlands which are required to help protect coastal communities from the results of storm surges, rising sea-levels and extreme weather. Offshore, these MPAs will protect vulnerable habitats and secure spawning grounds for various marine species, therefore helping to sustain fisheries and ensure long-term benefits important to food and job security.

The new MPAs will increase the protected portion of South Africa’s territorial waters from less than 0.5%, to 5%. The government has undertaken to get this figure to 10% by 2019.

What does this mean for you?

Scuba diving

If you’re a scuba diver, you probably know that diving in a Marine Protected Area – particularly in a no-take zone – is an extra special experience because of the abundant fish and other marine life. The prospect of richer, more diverse dive sites to explore is an exciting one, but there are more benefits to this proposal than just enhanced eco-tourism opportunities.

Scuba diving businesses will have to acquire permits from the Department of Environmental Affairs (for about R500 per year) to operate in the Marine Protected Areas. (This has been in force for some time, and ethical dive operators in Cape Town who take clients diving in any of the existing MPAs should be in possession of a permit already.) There are also the permits issued to individual scuba divers (for about R100 per year, obtainable at the post office) to dive in an MPA – you will see this mentioned in Tony’s newsletter now and then, as a reminder.

Environmental protection

Some of the new MPAs are in offshore regions that would otherwise be at risk from destructive trawl fishing and other exploitative activities such as mineral, oil and gas extraction from the seabed.

Many of these MPAs will, like the Tsitsikamma MPA, serve as nurseries for fish stocks. Recreational and commercial fisheries will benefit from allowing the fish to spawn unmolested in protected areas along the coast. Holding ourselves back from fishing everywhere, at every opportunity, shows long-term thinking, and will have short-term benefits as well as for future generations.

Undesirable activities

Not all of the MPAs will be closed to fishing – those of you familiar with the network of protected areas around the Cape Peninsula will be familiar with this idea. For example, a number of pelagic game- and baitfish species may be caught within the Controlled Pelagic Zones of the Amathole, iSimangaliso, Protea and Aliwal Shoal Marine Protected Areas. Commercial fishing permits may also be issued for use in the MPAs.

Existing discharges of effluent are permitted to continue – specifically into the Aliwal Shoal MPA.  This means that SAPPI may continue to pump wood-pulp effluent onto the dive sites there.

What to do?

If you would like to show your support for the proposal – and who doesn’t love a well-chosen MPA? – send an email to MPARegs@environment.gov.za. You have until 2 May 2016 to do so, and you can include any other relevant comments about the MPA proposal in your missive.

You can download the full document detailing the proposed new MPAs complete with maps, management regulations and co-ordinates (a 336 page pdf) here.

Tony and I are looking forward to passing over some of the new MPAs on the Agulhas Bank (maybe numbers 11 and 12 on the map above) next year – without getting wet. You can come too! (But you may have to impersonate a twitcher.)

Who to thank?

This project has been spearheaded by a team at SANBI (the South African National Biodiversity Institute) led by Dr Kerry Sink. Dr Sink has been awarded a prestigious Pew Fellowship in Marine Conservation for 2016, and her fellowship work encompasses a range of projects aimed at strengthening and expanding South Africa’s network of Marine Protected Areas.

We are extraordinarily fortunate to have a scientist and conservationist of Dr Sink’s calibre as a champion for MPAs in South Africa. So you can thank her!

Weekend dive plans

Sunday: Launching from the Simon’s Town jetty at 8.30 am for Maidstone Rock / 11.00 am for Atlantis

I think most people are keen for summer to arrive. I know I am. We dived last Friday at Atlantis and Boat Rock and had pretty good conditions – thank you to Arne for the photo above! Last weekend was a washout and the week has been dry thanks to the spring tides, swell and some wind.

The whales heard my complaints from last week, and on Friday a young whale breached in front of us again. This time while Geoff was holding the camera and he got a great photo!

False Bay is currently flat but not very clean. We are meant to have two days of westerly or north westerly winds so I think Sunday will be an option. There is also less swell on Sunday. I don’t think it is going to be paradise, but it will certainly improve over what we have right now.

We will launch on Sunday from theSimon’s Town jetty at 8.30 am for Maidstone Rock and 11.00 am for Atlantis. This is the plan, but the dive sites may change as I prefer to dive in better visibility if we go that far south, so will change sites to suit the conditions.

In other news

Diarise Diversnight 2015 for the evening of Saturday 7 November! More details to follow.

Also, as of yesterday we are a PADI Resort Dive Centre – the only major difference so far is that we now appear here

Newsletter: Loose ends

Hi divers

Weekend plans

Saturday: Launching from Hout Bay to the BOS 400 and Tafelberg Reef

Text me or reply to this mail if you want to dive.

We did not manage any diving last weekend as the boat was scheduled to launch in Gordon’s Bay for the Aqualung Fun Day on Saturday but we were cancelled on Friday evening because of bad visibility on that side. Sunday was a howling south easter day so no diving was done.

This weekend has a forecast similar to last weekend but with a few differences. The 3 metre swell that is in every forecast does not appear to be around as the Atlantic wave buoy registers 2 metre swell at the moment and False Bay was relatively flat today. The wind is another matter… There is however less wind on Saturday, so an early launch in Hout Bay is on the cards. We will dive the BOS 400 and Tafelberg Reef. Sunday will be too windy for my kind of diving.

Thanks very much to Jerrel for this week’s photo – taken two weekends ago on a dive to Roman Rock.
