Newsletter: Birds and dolphins

Hello everyone

This was the sight that we experienced at Long Beach while kitting up for a days diving.

Finally a weekend of diving!!!! We had really good weather this weekend and despite a rather large swell in the Bay the conditions were good. Saturday we spent the morning doing a Divemaster mapping project, the target: a concrete yacht that sank some years ago and that now lies 25 metres inshore of the north western yellow marker buoy at Long Beach. You can read all about it here.

Navigating our way out there  it suddenly seemed to get a little darker, more so than when  the clouds cover the sun and at the same time Corne surfaced to get a bearing only to find the surface covered with hundreds of cormorants. I was waiting at the bottom and was amazed at these birds’ ability to dive, stop suddenly, look around, then swim off.  I am not sure who got a bigger fright, them or me, but suddenly they seemed to be everywhere, perhaps our bubbles made them think there was a school of fish they could feast on, but instead they just found neoprene clad divers, way bigger than they could muster so they went off somewhere else. We saw them all again on Sunday, this time further out and from the surface.

Saturday afternoon five of us were back in the water and whilst swimming around the centre platform of the wreck these klipfish seemed keen on conveying some form of message to us  so they all lined up. I never did get to work out what they were trying to say… So much to learn in the ocean.

I can honestly say that I cannot remember a dive where I have not seen something new, or a creature I have seen before doing something new. We see warty pleurobranchs  ploughing their way over everything lately but on Saturday I saw a few doing acrobatic swimming and performing the most amazing somersaults… So much for me thinking they were like snowploughs… They seem more like circus animals!

Sunday we spent on the boat, the first dive was to Maidstone Rock. Andrew was completing his Advanced course and Gerard and Cecil were … well, only they know! The second launch took us to a new reef discovered by Grant and Peter Southwood called Tivoli Pinnacles, near Roman Rock. Being  a new dive site we were possibly the first to see a few amazing features and Clare discovered her first underwater treasure… a hand wheel from either a stem valve or a fuel valve, with a diameter of 120mm and made of brass. It has clearly been in the ocean for some time given the amount of corrosion on the material (a salt water corrosion resistant material). We will clean it up and see what it looks like.

There was also what seemed to be a huge brass ring almost a metre across so this will be a dive site worth exploring further.

Despite two amazing dives on a flat calm sea with great visibility, the good stuff was not yet over and when we surfaced  we were treated to the sight of a flock of I would guess at least a thousand cormorants and then Grant took us for a ride to a point just off the Kalk Bay harbour where we witnessed a pod of around 300–400 Dolphins. All in all a very pleasant day of diving.

This weekend

On Friday I will be doing Discover Scuba  Diving students at Long Beach all day, then on Saturday will continue with the Open Water course started last weekend and more DSD students. There are also two promising boat days looming.

Sunday looks good for shore entries and we will dive with the cowsharks if the swell is small or perhaps A Frame and or Sunny Cove.

Congratulations

…are also in order for Kate, who last year in October arrived in Cape Town wanting to learn to dive. By the end of November she had done OpenWater, Advanced, Nitrox specialty, Night Diving specialty and Wreck specialty as well as Rescue and Divemaster. Back in the UK for Christmas she did a Drysuit specialty and an Equipment specialty, and returned here in April to do a Deep specialty and then achieve the highest non professional qualification, Master Scuba Diver. It did not stop here and we dived as often as possible over the last few weeks to get her log book up to 100 dives and today she finished her Instructor course and Instructor Examination in Sodwana and is now officially an Open Water Scuba Instructor. Well done Kate! To achieve this much in such a short period of time takes determination, hard work and commitment.

DAN talks

We attended a DAN talk last week on ears at one of the local dive centres. It was run by DAN SA and we had a doctor talk us through what goes on in the ear and why whilst diving and the importance looking after those pink bits. We also received a free diving emergency booklet that has lots of info on handling diving related issues. These talks will be on a monthly basis and the next one will most likely be about lungs… So if you dive and have lungs… You should be there… It’s free and its very valuable knowledge to have.

If you wish to dive this weekend please text me sooner rather than later because the weather is good and the bookings will fill up.

Newsletter: Who is a lunatic?

Hi everyone

Diving is often called an extreme sport, why, I don’t know but if you think diving is risky look at these options (photos taken by me, this week).

Two weeks ago I was raving about the fantastic weather and just to exclude me from a career in weather forecasting the ocean put me in my place and delivered this, a grumpy sea with an 8 metre swell and strong winds… Waves larger than the Clan Stuart eliminating any chance of a casual shore dive!

Without the option of diving and stalking creatures underwater I decided to stalk a few creatures on land instead.

The weather and diving this weekend

NO COMMENT!

However…

Saturday looks (text removed to protect my ego) for shore diving, somewhere along the coastline and I will decide where early on Saturday morning once I have seen the sea with my own eyes. Sunday we will be on the boat, three launches with Long Beach pick ups (Grant will decide where when he has seen the ocean with HIS own eyes).

be good and have fun

Bookshelf: The Devil’s Teeth

The Devil’s Teeth – Susan Casey

Devil's Teeth
Devil's Teeth

It’s rare for me to take as complete and instant a dislike to the author of a book as I did in this case (Elizabeth Gilbert of Eat, Pray, Love fame is the only other example I can summon to mind). Susan Casey is a magazine journalist who counts employment at O Magazine among her career highlights – but this isn’t the reason I took a dislike to her… Keep reading.

I suppose I am looking for a book about sharks that doesn’t exist. Briefly, here and there, this was that book. Casey describes the Farallon Islands, remote and hostile rocky outcrops some 50 kilometres from San Fransisco. Like our Seal Island in False Bay, the Farallones are home to many marine mammals and a large number of great white sharks (some of epic proportions).

Casey describes the birth of her obsession with the islands (she watched a TV show) and the sharks that call them home, as well as their history as a source of seabird eggs (they are an important nesting site). She recounts various visits she took to the islands, culminating in a long stay in 2003.

Casey’s ruminations about how dirty her hair was, what she packed for the trip to the islands, how clueless she is about boats, and how obsessed she – personally – is with white sharks are uninteresting, but her descriptions of the sharks themselves, the research being conducted with them, and the individuals – incredible to a man – conducting that research, are at times rewarding. A keen objectifier of men (like Elizabeth Gilbert, actually), Casey spends a lot of time describing the rugged good looks and well-defined musculature of the various researchers and scientists she encounters – really classy, and respectful of them as scientists and individuals rather than as eye candy. HA! I did wonder more than once if a continuation of this line of thought could explain how she managed to secure a stay on the islands despite them being officially closed to visitors…

Fascinating nuggets are, however, gleaned here and there. The predations at the Farallones generally do not involve the breaching we see at Seal Island, perhaps because the sluggish elephant seals living there do not require the same degree of exertion as frisky Cape fur seal pups do. The attacks mostly take place at high tide. The observations of Ron Elliott, a commercial diver who harvested sea urchins at the islands (the only one who dared) are fascinating – he’d see sharks on almost every dive he did, and hid from them under the rocks where necessary. Upon climing into the water, he’d duck straight under his little boat so as to avoid presenting an interesting silhouette from below.

On two occasions orcas killed a white shark at the island (in one case by holding the shark upside down until it drowned); after both predations, the other great whites vanished – just disappeared en masse. This is intriguing. Many marine mammals pass by – the islands are a popular whale watching location and up to 60 blue whales have been sighted at once. One of the researchers even became the first (and I think only) person to observe humpback whales copulating there. Apparently it takes two… Plus an assistant!

Something else I discovered here that I didn’t know is that the Monterey Bay Aquarium in California, one of the foremost aquaria in the world, has had great white sharks on exhibit on several separate occasions, starting in 2004. They don’t keep the sharks indefinitely – they grow fast – but they’ve managed to keep five sharks mostly happy and healthy, before realeasing them (tagged) back into the wild. The reasons for release varied from increased size, increased aggression, to refusal to feed.

Ultimately, this book is an account of a tragedy caused by its author, who seems unaware of the extent of the damage she wrought, and hence unrepentant. She forced herself – there’s no other word – into a delicate web comprising the predators, prey, and the scientists who observed their interactions, and then tore down part of the web by her very presence. Because of her stay on the islands, Peter Pyle, the researcher in charge of the Shark Project on the Farralones, lost his job. Thanking him profusely in the acknowledgements doesn’t really cut it, especially after quoting Pyle elsewhere in her book as saying that he loved the Farallones, and being on the islands, “more than life.”

Aside from shutting down an entire shark research project singlehandedly and causing a ten year veteran of the project to lose his job, Casey also misplaces a borrowed sailboat and breaks the law repeatedly and with gusto. If I’d made such an utter fool of myself, I wouldn’t have written a book about it, but she glosses over her responsibility so thoroughly that I suppose some readers may fail to ascribe to her the blame she deserves.

Buy the book here if you’re South African, otherwise here. Actually, don’t buy it – this woman doesn’t deserve any support at all.

Movie: Finding Nemo

Finding Nemo
Finding Nemo

I adore this movie. It’s hilarious and meticulously researched. We refer to it often at the Two Oceans Aquarium – it’s a great point of reference for the children when we tell them that the sea anemone they are looking at is like Nemo’s home on the reef.

We meet a phenomenal array of creatures, from Nemo and his dad Marlin the clownfish, Bruce the vegetarian shark, to Crush the turtle, who shouts “Righteous, dude!” as he rides the East Australian Current (EAC). Little facts are included at every turn… Nemo has to brush in the morning before he goes to school: not his teeth, but his body against the tentacles of his anemone residence. This, as his father points out, prevents him from being stung. Crush the turtle is 150 years old.

We see reef, harbour and shipwreck environments as well as blue sea as Marlin and Dory ride the EAC. The artwork is gorgeous and the fish and birds are rendered with accuracy and charm.

There’s a strong message of respect for the ocean alongside the usual Disney message (it’s ok to be different… we all have something special to do… be a true friend and help others). We see that Gil, another fish in the fish tank that Nemo finds himself in, misses the ocean and has the symptoms of depression. Even a child could understand that the diver’s action in taking Nemo off the reef at the beginning of the movie was wrong – he was not “clinging to life”, as the dentist puts it, but thriving.

My favourite character is Dory (voiced by Ellen DeGeneres), who reminds me strongly of my friend Tami (she protests). Her efforts to “speak whale” are hilarious.

The DVD can be obtained here if you’re in South Africa, otherwise from here.
