Newsletter: Back in Town

Hi divers

Weekend dive plans

No diving The weekend is too windy for good diving, with strong south easterly winds starting on Friday evening. We won’t be diving, but I’ve got a boat launch tomorrow and I’ll share the conditions on facebook.

Newsletter: Electric sea

Hi divers

Weekend dive plans

No diving

We won’t be diving this weekend, and there won’t be a newsletter (or diving) next week, but we’ll be back in business after the public holiday on Heritage Day (24 September). This weekend, Saturday looks good, and Sunday ok for diving.

I launched for divers on Tuesday, and they had fairly good conditions (5-6 metre visibility at Sherwood Forest and Castle Pinnacles) but the surface conditions deteriorated as the day progressed and the wind picked up.

This past weekend, helped by the south easter and then the heat, a thick red tide got caught in Fish Hoek bay and as a result we were treated to some incredible bioluminescence (caused by a type of plankton that fluoresces when disturbed by wave action) on Saturday evening.

This occurs at least a couple of times a year, usually in spring and autumn, on this side of False Bay (and it often makes its way around to the Kogel Bay area on the eastern shore). It is an incredible sight to see. There’s a little video here (pardon the screaming – the beach was packed and the people were excited).

Anyway – see you in 10 days.

False Bay is currently a frothy mess from very strong south easterly winds today. The wind dies down for the next two days but I very much doubt the visibility will get better than a metre or two, so we have no dives planned. On the plus side, there are several days next week that look like decent diving days.

Hi divers

Weekend dive plans

Sunday: False Bay dives, conditions permitting

The tree in our driveway has a tiny green bud containing a new leaf. Despite the cold this week, I declare spring.

False Bay is quite surgy after some large swell this week, but I hope it’ll have settled down enough by Sunday for some reasonable diving. I’ll only make the call on Saturday afternoon; please let me know if you’d like to be notified of any developing plans.

There’s a fascinating update this week from Shark Spotters on False Bay’s white sharks (spoiler: they’re awol but we’re not quite certain why yet) – read more here.

Pool sessions!

This weekend I have pool sessions planned, so we won’t be getting salty. But the weather looks quite good if you do plan to head out. Saturday is probably the best day for diving as there is a slight chance of rain on Sunday. If you’re in town, remember that it’s the Blisters for Bread walk around Green Point on Sunday, which might cause a bit of traffic.

It is still winter – time for lots of swell, and sometimes odd wind directions. There is all of that this weekend, with too many “maybes” at play to make a diving plan. Hout Bay may work on Sunday but the same could be said for False Bay. I don’t think the odds are too good so we have nothing planned.

Bookshelf: The Seabird’s Cry

The Seabird’s Cry: The Lives and Loves of Puffins, Gannets and Other Ocean Voyagers – Adam Nicolson

The Seabird's Cry
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.

You can read rapturous reviews of this book on The Guardian’s website, on Literary Hub, and at the Financial Times.

Get a copy here (South Africa), or here. It is available for Kindle, but you’ll have to search for that one yourself!

Saturday morning looks to be the best time this weekend for a spot of diving. We are heading offshore on a pelagic birding trip / hunt for fishing trawlers which means no inshore diving for us until next week.

Shark Spotters in brief

The Shark Spotters centre at Muizenberg
The Shark Spotters centre at Muizenberg

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.

For more information, visit www.sharkspotters.org.za.

(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.)

Newsletter: Still wintry!

Hi divers

Weekend dive plans

Sunday: Shore dives at Long Beach The water remains cold… But then it is winter. Both Saturday and Sunday should be reasonably decent for diving, but I think Sunday will be best. I will shore dive on Sunday, most likely around 10.00 am, once things have warmed up marginally. Let me know if you want to join us.

Turtle and seal rescue

The Kommetjie NSRI team rescued a seal and loggerhead turtle, entangled in fishing net, that washed up this week. The seal swam off, relieved, and the turtle is at the aquarium having some TLC and a health check, after which it will be released. Read all about it here.
