Newsletter: The joy of kelp

Hi divers

Weekend dive plans

No diving The forecasts vary wildly this weekend. Windy says howling south easter everywhere, whilst other sites say mild wind suitable for some Atlantic diving. The mountain will break some of the wind so I am sure Table Bay sites will be good, and Hout Bay much the same. I have students for the pool this weekend so there are no launches planned.

Kelp night

Learn all about kelp at the Two Oceans Aquarium next Thursday evening, 31 January. There will be talks on kelp science, kelp as a habitat, and kelp as a snack. Read more here, and book tickets at Quicket.

Camera housing

Clare is selling her Sony underwater housing that fits the Sony RX100 range of cameras. If you’re interested, drop me a mail and I’ll put you in touch with her.

Stompneuspunt beacon

During the course of a West Coast road trip late last year, we stopped at the unmanned Stompneuspunt beacon. This striking, squat structure sits at the southern end of St Helena Bay. To get there, we had to drive through the eerie, deserted, badly laid out Shelley Point golf estate development (tell the guard at the gate that you want to visit the lighthouse). Persistence through the maze of narrow roads turning in upon each other is well rewarded.

The green-painted lantern house atop the structure looks like a minaret, and the whole building looks like an exotic transplant from the Middle East. The beacon is situated on a beach of coarse sand covered with thousands of empty mussel shells and inhabited by flocks of cormorants. The mussel shells wash up after winter storms and red tides, and because of predation by rock lobsters and other shellfish.

The beacon was commissioned in 1934, at which time it was a pyramid-shaped wooden structure. The present building was completed in 2001. The tower is 8 metres high, and the focal plane of the light is 12 metres above sea level. The intensity of the light is a modest 1,403 candelas, but this beacon doesn’t have to compete with much in the way of onshore light pollution. It’s visible from 10 nautical miles away.

My favourite lighthouse in Port Elizabeth (the others are the Hill lighthouse and the Deal light) – and possibly anywhere in South Africa – is Cape Recife. It’s magnificently situated on a headland at the south end of Algoa Bay, surrounded by shifting sand dunes (which sometimes complicate road access after high winds) and rocky reefs. I visited it very early one morning, with only fishermen about.

Cape Recife lighthouse was commissioned in 1851, the fourth lighthouse to be commissioned in South Africa. Of those still operational, it is the third oldest (after Green Point and Cape Agulhas). It comprises an octagonal masonry tower. It was originally painted with bands of white and red; today (as you can see from the eleventy million pictures I took) it’s painted black and white. This change was made in 1929.

The tower is 24 metres high, with focal plane 28 metres above sea level. The light’s intensity is 4,000,000 candelas (compare the Deal light’s 592,000 candelas) and is visible from 29 nautical miles away.

The Cape Recife light has the only large lens in South Africa that rotates on a steel track, resting on brass and steel rollers. The other large lenses (for example at Slangkop) float on a bath of mercury, an arrangement which has the advantage of being virtually frictionless. This allows for much faster and smoother rotation, with no wear and tear on the component parts. Unfortunately frequent exposure to mercury entails serious health hazards.

The lighthouse is situated next to the Cape Recife nature reserve, which has excellent bird watching. A small fee to enter the area is required – permits obtainable at Pine Lodge Resort (or possibly at the gate). Check before visiting. No diving is allowed in the area, and you will be fined if you are found with dive gear in your vehicle. SANCCOB (formerly SAMREC) runs a seabird rescue centre on the way to the lighthouse. If you visit SANCCOB, and get your entry ticket stamped to prove it, the permit fee is waived.

It’s possible to go inside the lighthouse on weekdays, by calling ahead to make an appointment. The number on the sign outside was (041) 507 2484. If dialling from outside South Africa, replace the (041) with +27 41.

You need this: the Shark Spotters smartphone app

The Shark Spotters app
The Shark Spotters app

After a successful Back a Buddy campaign, Shark Spotters launched their free shark safety smartphone app in the summer of 2016. The app has had excellent uptake by water users of all stripes, but I’d like to draw it to your attention in case you aren’t familiar with the ways in which it can make your beach life better and safer! Whether you’re a surfer, a diver, an ocean swimmer, a beach comber, or someone who looks forward to long summer days under an umbrella on the sand, the Shark Spotters app can make a difference to you.

The list of Shark Spotters beaches
The list of Shark Spotters beaches

Shark Spotters operate at eight beaches around the Cape Peninsula: four (Muizenberg, St James/Kalk Bay, Fish Hoek & Caves, Kogel Bay) year-round, and another four (Glencairn, Clovelly, Monwabisi and the Hoek, Noordhoek) from October to April, during the warmer months.

The app allows one to set a home beach – you can see from the image above that mine is Fish Hoek – and when you start the app, you’ll get information for your home beach immediately. Tapping on the home beach block at the top of the screen (where it says “Tap for more”) brings one to a series of screens that you can navigate through by swiping the bottom block on the screen.

The information provided is extensive. You can see information on the last three shark sightings at your home beach, the weather and sea conditions (temperature, wind direction, tides, moon phase, swell), and information on what marine life is in the area. This latter information is not a nice to have so you can look out for dolphins from shore, but an important indicator of the likelihood of a shark being in the area. Dolphins, rays and schools of fish can draw white sharks, while sunfish (and even seals) may be mistaken for a shark when viewed from a distance by an untrained observer.

There’s also information on what facilities are available at the beach, and a short video for each beach, usually taken each morning, showing the prevailing conditions.

All this information is available for all the Shark Spotters beaches, not just your home beach, and you can view a different beach by selecting it from the list that appears under your home beach on the home screen.

Digging into the app, you can find a detailed list of all the recorded shark sightings, and in the settings you can turn notifications of sightings on or off according to your preference. I have them switched on, because I like to be reminded of a world outside the office.

Shark Spotters app menu options
Shark Spotters app menu options

The further menu options, shown above, give you access to a large amount of data about the Shark Spotters program, the exclusion net at Fish Hoek beach, how the flag system works, great white sharks, and more. Most of the menu options also provide links to more detailed information online, if you want to know more.

You can download the app for iOS here, for Android here, or use the download links from the Shark Spotters website. The app is completely free of charge, but Shark Spotters is funded by the City of Cape Town, Save Our Seas Foundation, and other generous sponsors, including individuals. Shark Spotters welcomes donations. Click here to donate.

Merry Christmas divers!

If you celebrate Christmas, here are our very best wishes to you and your family. This year we’re having a white Christmas in Stockholm (Clare’s first proper brush with snow… I’ll let you know how many snowballs I manage to land before she exacts retribution)!

If you’re in or on the water this week, be safe and have fun, and spare a thought for – and say thank you to – the first responders who work to keep us all safe, even during holidays. These often unseen angels include the NSRI, lifeguards, Volunteer Wildfire Services, police, traffic officers, and law enforcement.

Here, also, is a (cellphone) picture of one of the aquarists from the Two Oceans Aquarium, feeding the fish in the I&J Ocean Exhibit this December. The apparent rain of snow is tiny bits of whatever the fish were getting for lunch that day – most likely chopped up squid and white mussel.

The Hill lighthouse (decommissioned)

A visit to Port Elizabeth can be very rewarding for the lighthouse enthusiast, with no less than three lights in close proximity. The Hill lighthouse is the oldest, and is almost in the centre of the town. It was commissioned in 1861, at which time it was seven metres high, and retired in 1973 when the competition from surrounding city lights became too intense.

It is a brick structure, and was originally stone coloured. In 1903 the eight panels of the tower were painted alternate bands of white and red, and in 1907 the entire tower was painted white (as it is today). In about 1921 a red band was painted half way up the tower.

The lighthouse keeper’s cottage below the tower was built in 1865 for Charles Hammond, the first lighthouse keeper, who served until 1881.

The Hill lighthouse was raised by nine metres during 1929-1930 in an attempt to distinguish it from the lights of Port Elizabeth, and was finally replaced by the Deal light, a short distance out of town, when it became apparent that as the city got larger and brighter, the Hill light was being overwhelmed.

There isn’t a lot of information available about the optics of this lighthouse, given that it hasn’t been in use for 45 years. It appears that a Chance Brothers lamp apparatus was installed in 1903, with a German-built optic, but more than that I haven’t found. Chance Brothers were glassmakers, who pioneered surrounding lighthouse lamps with a cage of fresnel lenses to make the light visible over greater distances.

The Hill lighthouse is situated in the Donkin Reserve, a surprising open space high on a hill overlooking the city and the harbour. The area is planted with indigenous vegetation, and boasts beautiful open spaces and a magnificent 470 square metre mosaic (the Piazza Mosaic) showing elements of the history and natural attributes of the city and surrounds.

Also on the Donkin Reserve, and right next to the lighthouse, is a ten metre high stone pyramid erected by Sir Rufane Donkin in memory of his wife, Elizabeth, after whom the city was named. Donkin was acting Governor General of the Cape Colony from 1820-1821, sent here to recover from the death of his young wife.

It’s possible for the public to visit and climb the lighthouse, from which beautiful views of the city are visible. As with most lighthouses, the climb is narrow and vertiginous, but recommended! You can find more information about visiting hours here. There’s a nominal fee but the opening hours are far more favourable than most lighthouses I’ve visited. You just need to go into the tourism office under the lighthouse, tell the person on duty you want to climb the tower, and get further instructions there.

Cape Town’s visible shipwrecks: Commodore II finds a home

Commodore II by the Milnerton lagoon
Commodore II by the Milnerton lagoon

I am happy to report that the Commodore II has finally been paid the attention she deserves, and moved to a permanent position on the shore of Milnerton lagoon. SAHRA began a process in late 2016 (when the wreck still lay on the beach close to the lagoon mouth) that has finally concluded with the wreck being moved on Friday 23 November. There are some pictures of that endeavour here and here.

View towards Lagoon Beach hotel

We first wrote about the Commodore II in 2015, and I was amazed that a wreck with such a fascinating and high-profile history could have practically disappeared into obscurity. There appeared to be no desire from the keepers of our maritime heritage to protect her, and when she washed up the Milnerton lagoon during a storm in late 2017, it seemed that she would be carted away piecemeal for firewood before anyone realised what was being lost.

View of the Commodore II

Late last year, an enterprising local resident secured the wreck to the banks of the lagoon off Esplanade road, at his personal expense, to prevent it from washing around inside the lagoon and injuring paddlers or damaging the historic bridge further up. We wrote about his efforts here.

The new, and hopefully final location of the wreck is just next to the small parking area outside the Lagoon Beach hotel and Wang Thai restaurant. It’s entirely accessible at all hours of the day and night, and there are promises of interpretive signage to share the wreck’s history with passers by.

Tube worms cover the lower portion of the wreck
Tube worms cover the lower portion of the wreck

I went to visit the wreck a week after she was moved. Dried pond weed still covers some of the planking, and thousands of tiny tube worms cover the lower part of the structure that was submerged (I can’t tell what kind – most likely Ficopomatus enigmatus, the estuarine tube worm that thrives in brackish water).

It’s great that the Commodore II is now firmly on the radar as one of Cape Town’s historic shipwrecks, worthy of preservation. I’ll be updating my ebook to reflect her new location before year-end. Meanwhile, read about her chequered history here.

According to our weather station this week, the south easterly winds have arrived, and hopefully this is a signal for warmer weather to move in.

False Bay has been on and off this week with some swell, however the colour is not too shabby. I am launching tomorrow, and depending on what we find, on Sunday I’ll shore dive at Long Beach or boat dive from False Bay Yacht Club. If you’d like to dive, let me know.

Hi divers

Weekend dive plans

Saturday: Boat dives from False Bay Yacht Club

The forecast for Saturday looks rosy so we will launch from the Simon’s Town jetty at 9.30 and 12.00. Both dives will be shallow, most likely Roman Rock and Photographer’s Reef. False Bay is a little patchy so dive sites might change.

Turtles

Amazingly, we still meet people who don’t realise that baby sea turtles – and even big ones, if they’re poorly – can’t survive for long in the cold waters around the Western Cape. Luckily the Two Oceans Aquarium has a well-developed turtle rehab facility, where they look after turtle hatchlings and older turtles brought in by members of the public.

The turtles receive veterinary treatment, vitamin supplements, a healthy diet, and excellent care from a dedicated team of aquarists. The aim is to return all the turtles that regain sufficient health to survive independently, to the wild, as most sea turtle species are vulnerable. These turtles are released in each year in December, when the warm Agulhas current is at its closest to Cape Point, giving the turtles their best chance of survival. The most famous release story is Yoshi, who swam all the way to Angolan waters, and is now off Namibia again, heading south. Maybe she misses us.

If you find a stranded sea turtle, keep it safe and dry, and notify the aquarium as soon as possible. The NSRI can assist with large turtles, and know how to help. There’s more information on what to do here.

Like turtles? Want to read about turtle science in South Africa? We have just the book for you.

Diversnight 2018

This year, Diversnight is on Saturday 3 November. The aim is for as many divers to be underwater at 20h18 as possible. More details to follow closer to the time!
