Conditions look good for some weekend diving, but unfortunately I have other commitments so I can’t be the one squiring you around underwater.

Please keep safe on the roads and when you are out and about at this crazy time of year, and use this opportunity provided by Eskom to think about ways in which you can make yourself less dependent on fossil fuels. If that means romantic solar jar lighting year-round, so be it!

Christmas gift guide 2018

Chaps, Festivus (for those of you who find tinsel distracting) is around the corner. This year, as a principle, the gifts that I’m giving to the people I care about are skewed towards experiences, and when they are things, I’m trying to make them beautiful things that will enable my chums to live more sustainable lives.

Before I get going, however, can I point you to this excellent, far more comprehensive, far more inspired gifting guide over at twyg? Their first suggestion is “don’t gift at all”, and this is probably something well worth considering, if it won’t cause a domestic diplomatic incident.

Tinsel from the sea (Champia compressa)
Tinsel from the sea (Champia compressa)

Here’s a quick list of ideas in case you’re struggling.

An experience

A dive course or boat dive with Tony, a family photo shoot, a day out at Cape Point or up Table Mountain in the cable car, a digital magazine or streaming television subscription – use your imagination!

Something water wise

It’s likely that most of us will never, in good conscience, be able to resume watering our gardens the way we used to. For this reason, water wise plants are high on my list of excellent gifts for keen gardeners. For ideas of what plants to choose, your local nursery will help, or you and the avid coastal gardener in your life can consult this excellent book.

Something to minimise waste

  • A set of stainless steel or glass straws (Sustainable.co.za is one stockist), glass or copper straws (check out EbonyMoon for these), or a pack of paper or other biodegradeable straws to keep at home and/or carry around like a dork for use at restaurants.
  • A reusable coffee cup – Seattle Coffee Company sells beautiful Keep Cups, as do Vida e Caffe and many supermarkets. ecoffee cup sells beautiful bamboo cups, with a range of designs to choose from.
  • A reusable shopping bag – most supermarkets stock bags of some description, as does Faithful to Nature. 3friends has beautiful Shweshwe printed bags that are very special. We should all have a reusable shopping bag in our handbags, as well as several in the car.
  • A bokashi bin, which you can find at Builders Warehouse or at many nurseries. Don’t be grossed out – we have significantly improved the soil quality in our garden, and don’t put out any food waste or scraps with our garbage any more, thanks to diligent use of this nifty indoor composter!

Something to lift up someone else

Some deserving, marine-related recipients of a donation on your friend’s behalf are:

There are many more excellent non profits than just these three, and so much need, but do your research carefully. My rule of thumb is, if the founder’s face is plastered everywhere and it looks more like a personality cult than an NPO, it’s not a cause that I want to give my bucks to.

A donation of time is a way to do something great, and spend time with someone you care about. Promising to join a friend for a beach cleanup followed by a coffee (in your reusable cup, your treat) gives a gift to the planet, and the gift of time to someone you value. To find a local clean up, follow the Beach Co-Op (facebook) and Cape Town Beach Clean Up (facebook). The Two Oceans Aquarium also arranges periodic beach cleans. (Non-Capetonians, facebook and google search are your friend.)

Looking back

Previous years’ gift guides, which contain some good ideas – if I say so myself:

  • 2017 – for info on Wild Cards or My Green Cards, small specific gifts for divers and water people
  • 2015
  • 2014
  • 2013 – for info on gift ideas for readers
  • 2012
  • 2011
  • 2010

Be safe, be kind, be frugal, be wise! Thanks for reading.

Newsletter: Better than nothing

Hi divers

Weekend dive plans

Saturday and/or Sunday: Boat dives in False Bay

The forecast today is a little better for the weekend than it was earlier this week. There is some wind and some odd swell and swell direction changes but I believe it should be worth diving both Saturday and Sunday. Sunday will most likely be a little better. I have students on the boat on both days so there is not much space, however, if you are quick you can reserve a spot!

Things to do

It’s not as if one needs to actively seek out extra commitments at this time of year, but in case you’re at a loose end check out Wavescape’s Slide Night happening on Monday (you need to book in advance for this). You can get some adult education at UCT’s annual Summer School in January, and there’s something for you whether your interest is sharks or shipwrecks.

Sunday: A dive of some sort, boat or shore!

There is a better than average chance decent visibility will be found whether you dive Hout Bay False Bay, Table Bay or Gordons Bay. I think Sunday will be the better day and the most likely choice is False Bay for me.

The decision will, however, wait until late Saturday after I see what a drive around reveals. Text, mail or Whatsapp me to join.

Article: The Atlantic on how much of the sea is fished

The proportion of the world’s oceans that are fished has recently been the subject of two papers in Science, both of which used the same data set to reach different conclusions. One study concluded that 55% of the ocean is affected by fishing, while a follow up (using the original data set, but at finer resolution) concluded that the number is closer to 4%.

A janbruin emerges from a school of fish at Atlantis

Ed Yong of The Atlantic sets out the disagreement, and explains the subtleties and the points of view on each side of the debate. Far from being an insoluble  scientific crisis, the divergent findings show the iterative nature of the scientific process and the manner in which back and forth between scientists leads to progress. It brings to light important questions worth considering, ones that are more important than simply asking the original question of how much of the ocean is fished.

Instead, you have to ask different and more refined questions. How much of that fishing is sustainable? Which species are being targeted? How are they faring? Can they bounce back?

We’re in Port Elizabeth for a long weekend, so I won’t be running any dives. If you do go out, be safe and don’t go deeper than the bottom!

Baboons on the beach

Baboon on the beach Baboon on the beach

A recent low tide visit to the beach at Platboom near Cape Point, on the Atlantic coast of the peninsula, enabled us to watch a troop of Chacma baboons (Papio ursinus)  foraging for limpets, mussels and other marine snacks on the rocks at low tide. The baboons bite the tops off the limpets with their formidable incisors, or pry them from the rocks intact to get at the protein-rich flesh. They also eat mussels.

Baboons foraging for seafood at Platboom Baboons foraging for seafood at Platboom

This foraging behaviour is extremely rare among primates. In baboons, it is only observed on the Cape Peninsula and in one other species in Somalia. Matthew Lewis studied this troop of baboons as they foraged around the Cape Point nature reserve, and his thesis makes for fascinating reading. (Wild Card Magazine also featured Matthew’s research.)

Baboon on the beach Baboon on the beach

The amount of time the baboons are able to spend foraging on the shore is largely determined by the height of the tide, and by weather conditions. As a result, the amount of time the baboons spend seeking marine food sources is small compared with the time they spend looking for roots, bulbs, insects, berries, and small animals.

Low tide at Platboom Low tide at Platboom

These baboons are part of the Kanonkop troop which ranges freely in the Cape of Good Hope section of Table Mountain National Park and whose home range does not bring them into conflict with humans (or, as a rule, allow them access to any anthropogenic food sources). They were completely uninterested in us and our vehicle, unlike the baboons we see further up the peninsula around Millers Point, for example.

The weather forecast for the weekend is wild and windy, and definitely not diving weather.

Diversnight 2017 at Long Beach
Diversnight 2017 at Long Beach

We had a great night dive last Saturday evening at Long Beach. It was calm but crisp, and we spent a lot of time watching a vast array of fish and invertebrates marauding around on the sand, hunting for their dinner. Clouds of fish fry, so thick that at the beginning of the dive we couldn’t see our feet, provided food for an array of predators. There were a lot of divers in the water, and it was great to see the dive clubs take ownership of this community diving event. Watch out for Diversnight 2019!

Newsletter: Diversnight ahoy

Hi divers

Weekend dive plans

Saturday: Night dive at Long Beach – meet at 7.00pm

I took a look at Hout Bay as well as False Bay today, and neither look all that great. There has been big swell and strong winds this week so it’s a little messy. Saturday is a calm, quiet day with neither swell nor wind, so this should help settle the ocean enough for a decent night dive on Saturday evening. It is not inconceivable that very early boat dives could work on Sunday, however that’s a decision that can only be made late on Saturday.

Diversnight

Diversnight is this Saturday, 3 November. We plan to meet at Long Beach (the tide is against us for a jetty dive) at 7.00 pm. My plan is to start the dive just on 8.00 pm. There are several groups and clubs doing dives for Diversnight so there will be several shore-based people around to keep an eye on the cars.

If you are joining us please let me know sooner rather than later (it makes cake baking easier), and if you require any gear!

Newsletter: Playing the odds

Hi divers

Weekend dive plans

Sunday: Boat dives, location TBC

The odds are good that diving will be sort of okay on both sides of the peninsula, on both days of the weekend. We had 3-4 metre visibility yesterday in False Bay with lots of red tide patches. Strong south easterly winds tomorrow should push the red tide a little further into the bay.

The weekend has very little swell and although the wind does fool around a little, I think Sunday will be the best option. Hout Bay or False Bay I cannot say but will decide that on Saturday. If you’re up for a dive, get in touch.

Next Saturday, 3 November, we’re night diving at Long Beach. If you’re keen to participate in Diversnight, we’d love to see you. If you are going to need gear, let me know sooner rather than later.
