Greetings to you from this altered reality. There’s nothing to report on the diving front, but I did want to draw your attention to an important biodiversity project that might help to lift the lockdown blues this weekend, after you bake a loaf of sourdough.

City Nature Challenge – Lockdown Edition
It’s the City Nature Challenge this weekend, from tomorrow until Monday (24-27 April). This year it’s a bit different than usual (like everything, unfortunately) – we’d love to be doing this on the beach or underwater. But it’s not to be. Spot plants, birds and animals in your garden, and log the sightings using the iNaturalist app.
You don’t have to know what you’re spotting; experts will assist with identification after the fact. Get outside, learn some more about your surroundings, and blow away those video conferencing cobwebs. There’s a facebook page here, with some fun challenges (Bioblitz bingo, anyone?) and a facebook event here.
Stay at home, stay safe, and we hope to see you again when this has passed.
I’ve got students in the pool on Saturday, and Sunday looks too windy for dives, so we’ll have to wait to get in some salt water until conditions improve.
Turtle time
It’s the start of that time of year when turtles strand on the beaches of the Western Cape. What to do if you find one? Don’t throw it back into the sea. The Two Oceans Aquarium explains how you should proceed. Read more here.
The Seabird’s Cry: The Lives and Loves of Puffins, Gannets and Other Ocean Voyagers – Adam Nicolson
The Seabird’s Cry
This is such a wonderful book that I read it twice within the span of six months. In between my two readings, during the northern hemisphere spring, Tony and I visited Pembrokeshire in Wales. This is not the home of Mr Darcy, but rather the location of several islands on which seabirds breed. Seeing puffins, gannets and shearwaters in all their glorious breeding plumage animated Nicolson’s descriptions of their precarious lives. (I do plan to share some photos and details of that visit in future posts.)
Early in this book, Nicolson points out that seabirds are the only creatures on earth that are at home in the water, on land, and in the air. To most of us, albatross are perhaps the most familiar pelagic seabirds – Carl Safina’s Eye of the Albatross both introduced and immortalised these extraordinary ocean wanderers for a popular audience. Nicolson devotes a chapter to each of ten species of seabird, including albatross, and writes with such extraordinary lyricism that at at times it’s possible to mistake this book for something other than popular science.
This blurring of boundaries is quite intentional, and completely revelatory. Rather than sounding pretentious or foolish, as most of us would if we tried to channel Seamus Heaney while summarising scientific papers and interviewing researchers, Nicolson achieves a remarkable feat of science communication. He speaks of the wonder that comes not from ignorance, but from knowledge and understanding, and how powerful a thing it is to know the facts of these animals’ lives.
If the idea of trying to join the worlds of science and poetry (or literature, or culture) grabs you, you may enjoy this video of a conversation on the subject between Adam Nicolson and Tim Birkenhead, a professor of ornithology.
Seabirds are in trouble worldwide, more threatened than any other group of birds. They are facing – amongst others – challenges wrought by changing ecosystems as the climate warms and industrial fishing robs them of their prey. To help them, we need to act, and action comes after seeing and understanding. In this book Nicolson makes an appeal to a part of us other than the rational, fact-collecting, logical entity, and asks us to empathise with these strikingly “other” creatures. I urge you to read this book.
I had to write a short article about Shark Spotters a while ago, for the quarterly magazine of the company I work for. It was fun to write within the constraints of quite a punitive word count, and to try and emphasise the aspects of the program that I think are poorly understood by the public. Here’s the article:
Shark Spotters developed into Cape Town’s primary shark safety strategy out of two similar, informal initiatives. At Muizenberg and Fish Hoek in 2004, surfers arranged with lifeguards, car guards and trek fishermen to warn them when sharks were sighted. Today, Shark Spotters is a NPO funded primarily by the City of Cape Town, Save Our Seas Foundation, and public donations. It operates year-round at four beaches and during summer at another four. These are beaches that have both many water users and relatively common shark sightings.
A team of 30 spotters equipped with binoculars, polarising sunglasses and all-weather gear watch from the mountainside, and when a shark is sighted they notify colleagues at the beach to sound a siren and raise the appropriate flag. The flags indicate the current or recent presence of a shark, that spotting conditions are poor, or that it is safe to swim.
The spotters, all drawn from local communities, are trained in safety, first aid and shark behaviour. A further 10 team members deploy and retrieve the shark exclusion net at Fish Hoek beach during summer. Unlike the gill nets protecting beaches in KwaZulu Natal, this net does not catch sharks. It provides a physical barrier between sharks and swimmers. It is designed to be retrieved at the end of the day, or, to prevent entanglement, when there are marine mammals nearby. The Fish Hoek shark exclusion net is unique worldwide as an environmentally friendly shark attack mitigation measure.
It is the combination of favourable topography and surface-swimming sharks that makes Shark Spotters’ work possible and effective. The land around many of Cape Town’s beaches slopes steeply towards the sea, providing raised vantage points from which to spot. The sharks which pose the primary danger to water users, because of their size and curious natures, are great white sharks. Fortunately these sharks spend much time swimming on the surface, and their distinctive swimming style is readily recognisable.
Shark Spotters also conducts research on sharks to improve safety measures and provide management and conservation recommendations. As a result, the movements of great white sharks in False Bay are well understood. Sharks visit the beaches year-round, but with a distinct seasonal pattern. During winter the sharks congregate at Seal Island to feed on juvenile seals. During summer, sharks head for the backline of Cape Town’s beaches – probably to feed on the fish species found in False Bay at this time, and to rest in the highly oxygenated water close to shore. This is when they pose the greatest risk to water users.
Why support Shark Spotters?
I love the fact that Shark Spotters combines care for people with concern for the environment. The program takes a scientific stance backed by research, and has attracted worldwide recognition. It also provides training and employment for 40 residents of some of Cape Town’s most impoverished communities. I sit on the non-executive committee as a representative of Cape Town’s scuba diving community, and it’s a privilege to work with fellow water users and ocean lovers, and hopefully to provide a benefit to the greater community through our small contribution.
(Of course, lately white shark movements in False Bay are slightly less well understood than they have been, probably thanks to a pair of orcas whose irregular visits to Seal Island and Millers Point to hunt white sharks and sevengills seem to clear out the neighbourhood a bit! Fear not, Shark Spotters’ research is aiming to understand these changes, too.)
Seaweed Chronicles: A World at the Water’s Edge – Susan Hand Shetterly
Seaweed Chronicles
This is one of the best kinds of popular science book. It reads so easily that by the time you’ve absorbed enough material to attain a diploma in phycology (the study of seaweed), you also feel as though you’ve met and befriended a varied cast of individuals whose lives revolve – in various ways – around slippery marine algae.
It’s written by an American author, and the book centres squarely on the coast of Maine in the United States, obviously much loved by the author. It’s not clear initially that the geographical focus of the book is so narrow; some readers may want to know this in advance. While reading, I was grateful for the perspective that a Veld and Sea seaweed foraging course gave me on our local seaweeds.
Vignettes of seaweed-centred lives, from foragers turned businesspeople, to scientists, to shepherds whose flocks feast on seaweed during their coastal sojourns, introduce us to a cast of characters illustrating the many uses and commercial possibilities of seaweed, as well as the management and conservation challenges associated with its harvest. Seaweeds are pivotal in coastal ecosystems, providing vital habitat and sustenance. This isn’t just a science book (which some may find frustrating). It’s as much about the people as about the seaweed – but you will learn some science from it!
There’s a good review here at the New York Journal of Books.
Get the book here if you’re in South Africa, otherwise here.
Poacher: Confessions from the Abalone Underworld – Kimon de Greef and Shuhood Abader
Poacher
Abalone (perlemoen to locals) are inoffensive, slow moving marine snails, with frilly grey bodies covered by a knobbly shell that doesn’t look like anything special until you find an empty one on the beach and see the mother of pearl interior, polished for years by the body of the now-dead snail. Some people like to eat them; in Asia, many people like to eat them, and they are seen as a status symbol. They are farmed, at enormous expense and for staggering profits, at several locations along South Africa’s coast. When we visited an abalone farm in Hermanus several years ago, the tour guide told us that the demand for abalone from the east is essentially “limitless”. You can imagine, if you don’t know already, the financial temptation that such a creature might present.
Kimon de Greef is a South African journalist with a longstanding interest in perlemoen poaching and other forms of illicit trade. His reporting on abalone poaching has been longstanding, nuanced and detailed – one example here, and another here. A 2014 report (pdf) he wrote for Traffic, the wildlife trade monitoring network, is also worth a read. The second author of Poacher, Shuhood Abader (not his real name), is a former abalone poacher, and this book is his story.
Rather than a focus on statistics and an analysis of the scale of the abalone poaching problem in South Africa and how to fix it, Poacher comes at the issue in a deeply personal way, thus forcing us out of our righteous outrage and into the uncomfortable space of empathy with someone whose actions we disapprove of. We hear Abader’s story in his own words, with context provided by de Greef’s reporting and analysis.
Being a South African today is complicated. Our history gives none of us a free pass to relax into ignorant bliss, simple judgments or two dimensional interpretations of where we find ourselves and where we are going as people and a country. Yes, it might seem tiring for those of us whose privilege is showing, but the last several hundred years of our history demands a reckoning and we ought to show up for that, no matter what it requires. This reckoning extends beyond hard conversations and simple matters of ensuring everyone access to healthcare, education, property, jobs, credit, public spaces, and the like. It extends even to nature reserves and marine protected areas, those spaces that we view as sacred and untouchable. (I remind you of this discussion we had on the Tsitsikamma MPA – similar complexities exist for many, if not all the wild spaces in South Africa.)
Marine poachers are fairly visible to the scuba diving community. (Recreational divers are even mistaken for them on occasion.) The ISS has published two in depth reports (Steinberg and Goga) on the subject, some years apart. Abalone poaching is one of those issues that seems to cause particular outrage among scuba divers and the ocean-loving community, and this is, to some extent, understandable. Poacher, however, asks us to set aside that outrage and to learn another side to the story. This may disturb your equilibrium – the more the idea of there even being “another side” troubles or enrages you, the more strongly I recommend you read this book.
Please read this book. Get a copy at your local bookstore, online in South Africa here, or on Amazon.
If you read this in time, Kimon de Greef is discussing the book on the evening Thursday 4 July 2019 at Kalk Bay Books – phone them for details and to RSVP (essential).
There is a week of strong north westerly wind planned for us… Added to this is a fair amount of swell. As a rule wind from this direction will turn False Bay in to a viz wonderland. Once the swell fades, of course! I have no dives planned for this weekend, but I expect conditions next week to be very good.

Octopus fishermen strike again
UNBELIEVABLY, the octopus fishery in False Bay caught and killed another whale this week. If you haven’t signed the petition yet, please do.
Please also send an email to our new minster of Environment, Forestry and Fisheries, Minister Barbara Creecy. She has solicited suggestions for environmental policies that will shape the future of South Africa to the email address DEAMedia@environment.gov.za, and I reckon this is a good place to start.
I suggest letting your ward councillors know that this is unacceptable, even more so in a marine protected area, and that you are behind the City’s call to the government to put a stop to the whaling.
You could also send a letter to Herman Oosthuizen, South Africa’s representative (“commissioner“) on the International Whaling Commission. Dig around here for his contact details (a postal address), or try the email address listed on this paper – click on Author Information just under the list of authors’ names. It goes without saying that you need to be polite, reasonable and respectful when you contact people, no matter how emotional this issue makes you.
Abalone poaching – read all about it
Kimon de Greef, author of the outstanding book Poacher along with Shuhood Abader (the pen name of a former perlemoen poacher), will be discussing the subject next Thursday evening, 4 July, at Kalk Bay books. It’s bound to be a very popular event and rsvp is essential. Details here. (We’re reviewing the book on the blog on Monday.)
The weather forecast predicts that we are soon to be lashed with 50 km/h winds, a 7 metre swell, and no small amount of rain. It seldom is as bad as the forecasts claim, however the swell size and direction will hammer False Bay. Despite Sunday’s weather looking peachy, I don’t think the ocean will be, so we will plan for a dry weekend… It is winter after all.

Shark Spotters supporters program
We are proud to announce that we have signed on as official supporters of Shark Spotters. We are Silver partners, and for larger businesses there are higher levels of support on offer. (We are hoping to encourage some of the other dive centres to consider supporting Shark Spotters, too…) Individuals can also sign on to the supporters program, or donate in many different ways.
We’ll write a blog post with more information soon – but in the mean time, we’re very happy to be contributing to the important work of Shark Spotters. If you’d like to as well, visit their website to find out how to lend your support, or drop me an email and I’ll connect you with the right people.
We are in a week long period of practically windless days, not quite winter temperatures and not too much of the dreaded, huge winter swells. You could choose to dive on any of the three days this weekend, or all of them, and I have picked Monday. We will launch from Simons Town at 9.30am and 12.00pm for Atlantis and Photographer’s Reef. Let me know if you’re keen to get out on (and in) False Bay.
Brydes whale showing his head
Whale entanglement
It’s been a horrible week. A beautiful Brydes whale became entangled in the ropes of the experimental octopus fishery in False Bay, and drowned. Read about it here (there are some disturbing photos, so take care). In response, there’s a petition to end octopus fishing in False Bay – please sign it.
Can I also encourage you to amplify this issue outside of your usual social networks, who are probably ocean-loving people or friends of ocean lovers, and know about this already. Write an email or call the Department of Environmental Affairs, contact the provincial government, talk to your elected representatives, write to the newspaper. There are some other contact details to be found in one of the links we provided in this newsletter from 2014 that may or may not be useful – sadly this is not a new issue at all.
Beach cleanups
There’s a beach clean up in Cape Town practically every weekend, and it’s fantastic. To find out when they are, follow The Beach Co-Op (facebook / website), and Cape Town Beach Cleanup (facebook / website) to start with. Luckily South Africans are used to doing things themselves, and while the amount of trash recovered is eye-watering, it’s wonderful to see how many people are getting involved with looking after their environment.
Sunday: Boat dives from False Bay Yacht Club to Roman Rock
We are out on the boat tomorrow for a False Bay crossing – a swim – from that side of False Bay to this side. I won’t be swimming. It’s for a good cause and if you want to show support visit the Mad Swimmers facebook page. I don’t expect to be done much before nightfall so we will skip Saturday and launch on Sunday.
It’s been a while since dived the Northern Pinnacle at Roman Rock so that will be the first dive, and the second will be the ledge and channel slightly south of the pinnacle.
We hope you’ll use your time underwater to record some species and log them as soon as you’re on land again, but other very cool sounding events include rock pooling with ocean rockstars George and Margo Branch on Monday late afternoon (details here), and, if Monday is tricky, there’s a tidal pool bioblitz on Saturday afternoon that promises to be a lot of fun (details here).
If this is all Greek to you, check out last week’s newsletter for some links and more detailed background info.
