Newsletter: Never easy

Hi divers

Weekend dive plans

Boat dives on Saturday or Sunday, swell permitting

The weekend outlook is not that easy to call. A 4 metre, long period swell is due tomorrow. How much of it arrives and precisely when is difficult to say, as the forecasts on the more frequently used weather sites are quite different.

Hout Bay was surprisingly flat today when I went to take a look (the boat had its annual SAMSA survey today) and False Bay had far more swell than expected. For both days this weekend the wind is favourable, so it all really hangs on the swell.

I would like to launch either Saturday or Sunday but will make that decision midday tomorrow. If you’d like the option of diving, reply to this mail, sms or Whatsapp me.

Last weekend we dived in the I&J Ocean Exhibit at the Two Oceans Aquarium. It’s an experience that comes highly recommended. The picture above is of Sandy, a rescued green turtle whose shell was badly damaged by a boat propellor, looking at her reflection in my camera lens.

Hi divers

Weekend dive plans

Sunday and Monday: Boat dives (location to be decided)

Last weekend we did some boating in Table Bay as a support boat for the Robben Island to Big Bay Freedom Swim. The remnants of the swell on Thursday and Friday was enough to give the swimmers a sizeable challenge with strong currents, choppy surface conditions and very cold patches of water.

The swell climbed from under 2 metres to a little over 5 metres this morning.  This means diving tomorrow is pretty much out, as is diving on Saturday (thanks also to the Two Oceans Marathon). The swell drops off during the day on Saturday so both Sunday and Monday should deliver some reasonable diving conditions.

It is difficult to say whether Hout Bay or False Bay would be better on Sunday and Monday, but I will make that decision late on Saturday afternoon. I have Open Water and Advanced Open Water students so one day is likely to include a deep dive to more than 18 metres.

If you are keen to dive on Sunday or Monday, let me know and I’ll schedule you in!

Hi divers

Weekend dive plans

No diving planned

We have some intense wind and swell coming our way in the next few days, and the weekend does not look suitable for diving.

Testing a self-inflating life jacket

If you’ve been on our boat, you may have noticed that I always wear a life vest. It’s a slimline one that we purchased in Denmark a few years ago. The vest contains a small gas cannister with a pellet (looks like a headache pill) that releases the gas in the cannister and inflates the jacket when the pellet gets wet enough to dissolve.

When we went back to Copenhagen between Christmas and New Year, we purchased replacement cannisters, thinking that for safety’s sake it would be wise to service our life jackets to ensure that when we need them, they’re in tip top condition.

The question then arose as to what to do with the existing, unused cannisters in the life vests. Since you can repack the vest with a new gas cannister and dry pellet after deployment, and neither Clare nor I had seen one of these life jackets in action before, we decided to let it fire off in the swimming pool. Here are the results:

It definitely renewed my confidence in the life jacket, an important component of our safety gear, and (as you can hear in the video) provided some significant entertainment for my camera person Clare.

Newsletter: Watching waves

Hi divers

Weekend plans

Saturday: Big wave surfing at Dungeons (we will watch, not surf)

Sunday: Boat dives in False Bay, from Simon’s Town jetty

The Bay has been on and off this week with some swell interfering with good diving. A 7 metre swell is expected tomorrow and this means that Dungeons may be worth a look early on Saturday. Odds are the swell doesn’t quite reach the forecast size, and Sunday diving in False Bay may pan out.

Text, whatsapp or email me if you want to be on either list and I will keep you posted… Saturday big wave watching or Sunday False Bay diving.

Things to do

The floating book shop Logos Hope is at the V&A Waterfront until 11 July.

Newsletter: Clean out

Hi divers

Weekend dive plans

Sunday: Launching from Simon’s Town jetty at 7.45 am to Roman Rock

We have been out a couple of times this week and False Bay is really clean. Visibility today south of Partridge Point was easily 15 metres and the water is 15 degrees. There is some south easter and some swell for tomorrow and Saturday, but by Sunday it will all be gone and the water should still be clean.

Partridge Point this morning

The boat is booked by a group of up country divers on Sunday and I will launch for them at 10.00 am and 12.00 pm. I will do an early launch at 7.45 am to Roman Rock, for those of you interested in an early morning dip in False Bay. Let me know if you’re keen.

A Christmas dive with cowsharks

One of Cape Town’s best known dive sites is called Shark Alley, located close to shore near Pyramid Rock in False Bay. Here, broadnose sevengill cowsharks may be seen fairly reliably. There are times when they aren’t around (perhaps owing to a recent orca predation, or some other mysterious cause).

Jerrel filmed this beautiful footage on a dive at Shark Alley in December 2014, on a calm day with pretty good visibility. Look out for our boat, Seahorse, and of course the sharks. Thanks to Jerrel for the video!

If you’re curious as to how one conducts a dive with three metre long apex predators, check our our protocol for scuba diving with cowsharks. An ethical dive operator will also inform you of the likelihood of seeing the cowsharks, and whether they have been seen recently (i.e. in the last few days) by divers, before accepting money to take you diving at the site.

Saturday: Double tank dive at 7.30am launching from Simon’s Town jetty

Sunday: Double tank dive at 7.30am launching from Simon’s Town jetty

I’ve been out several times this week and we’ve found clean, green and brown water in False Bay during this week’s dives. We’ll do double tank dives on both days of the weekend, starting early. I haven’t picked sites for the weekend as we will go looking for clean water when we launch. If you want to be on board, you know what to do.

A Day on the Bay: Freedom Swim 2016

Maryna and Table Mountain
Maryna and Table Mountain

A day early in April was the date for the annual Freedom Swim, a 7.5 kilometre open ocean cold water swim from Murray’s Bay harbour on Robben Island to Big Bay near Blouberg. As we have in several previous years, we provided boat support for a swimmer.

This entails providing a straight course for the swimmer so as to minimise the distance swum, and keeping an eye on them to ensure that they don’t get too cold or show any other symptoms of hypothermia or distress. It requires communication with race control by radio, and a bit of boat and swimmer dodging in the early stages of the race when the water is thick with activity.

There was a 3.5 metre swell on the day, which made the ride out to the island a bit bumpy. As soon as we were in the shelter of the island, however, the sea was flattened as the swell diverted around the island. The water remained calm until we got quite close to shore, at which point the swell picked up. The final stretch from the rocks at Big Bay to the beach must have been very hairy for the swimmers!

Our swimmer, Maryna, swam in a wetsuit. She was part of the Lighthouse Swim relay team we supported last year. The water was relatively warm (13-16 degrees) clear at the island, and we could see kelp and quite far down into the sea. Great red streaks of water, probably an algae bloom, were filled with sea jellies (which stung Maryna, but she continued strongly). These were replaced by murky green water close to the shore, where the swell had lifted the sand particles into the water column.

It was a good day out, and always a pleasure to see Table Mountain in its majesty from the water.

How to help marine wildlife in distress

 

It’s not uncommon to come across marine wildlife – seabirds, seals, turtles – apparently in distress. This is not always the case, so before you mount a complex and dangerous rescue mission, or try to provide help where none is needed, it may be wise to get an expert on the telephone to help you determine whether it really is necessary. Fortunately there is a range of 24-hour wildlife hotlines to choose from, depending on what species you are dealing with.

Seals

Seals with plastic or fishing line around their necks should be reported to the Two Oceans Aquarium (if the seal was spotted around Cape Town harbour or the Waterfront), or, more generally to the SPCA Wildlife Unit on +27 (0) 21 700 4158/4159, or +27 (0) 83 326 1604 after hours and on weekends. Unfortunately the odds are your seal is probably not going to get the help it needs if it isn’t in the port of Cape Town or at the Waterfront; this doesn’t mean you shouldn’t do your darndest to advocate on its behalf.

You can help to deal with this problem at its source by retrieving any loops of plastic that you see floating in the water when you’re on a boat. Hout Bay harbour is a particular cesspit of plastic pollution, and with a nearby seal colony it’s a recipe for disaster. Cutting through any closed loops on plastic items (such as beer can holders) that you recycle or dispose of yourself also ensures that should the plastic end up in the wild, it won’t entangle an animal.

Seals found lying on the beach are usually not in trouble. Juvenile seals may rest for long periods – a couple of days at a time – on shore, and the most important thing to do is not to disturb them. They don’t need to be kept wet, they don’t need to be fed, and they can inflict a nasty bite. Encourage other members of the public to give the animal a wide berth, particularly if they have dogs. Lead by example. If the animal appears visibly unwell (fitting, for example) or is bleeding, then call the SPCA Wildlife Unit for a chat about what course of action is best.

Seabirds

Seabirds are most often found entangled in fishing line or plastic, pierced by fishing hooks, or, in the event of an oil spill, with oiled feathers. It is important to get help if possible, particularly for oiled birds.

SANCCOB has a 24 hour rescue centre which can be reached on +27 (0)21 557 6155 or +27 (0) 78 638 3731 (after hours & weekends). Their website provides the following advice to would-be seabird rescuers:

What to do when you have found an injured/sick/oiled seabird:

  • If you are unable to handle the seabird, SANCCOB will send out a unit to collect the bird.
  • If you approach any seabird, please approach with care. Some seabirds such as Cape Gannets and African Penguins have sharp beaks.
  • Have with you a towel, or blanket and wear protection over your hands and eyes. Use a towel/blanket to throw over the bird to catch it, ensuring that the bird is able to breathe.
  • If you have a large box ensure that there are holes for air before you place the injured/sick marine bird.

More information can be found here.

Turtles

During the autumn and winter months, juvenile and sub-adult sea turtles sometimes strand on Western Cape beaches. These animals are often shocked by the cold and in poor shape – they do not typically occur in Cape waters but are washed down in eddies of the Agulhas current.

Do not put the turtle back in the sea or into water. It is probably weak, dehydrated and hypothermic, and is likely to drown. Keep it dry, and call the Two Oceans Aquarium for further instructions and assistance. The aquarium rehabilitates and releases the turtles in warmer water when they are healthy.

Here’s detailed information from the Two Oceans Aquarium on what to do if you find a stranded turtle. Do the right thing!

Whales and dolphins

The City of Cape Town would like ocean users to report whale carcasses before they end up on the beach. This is mostly for public safety and resource allocation purposes, but if we can do anything to keep a whale carcass out at sea (or on a secluded non-swimming beach), it serves a conservation purpose as well. There’s a phone number you can use to do this – read more here.

If you come across a current or imminent live whale or dolphin stranding, contact the NSRI on +27 (0) 21 449 3500 immediately. They will activate the relevant authorities. Try to bear in mind that these events often do not end well for the animals concerned, as they are often sick or disoriented and impossible to assist. Be a help, not a hindrance, and obey whatever instructions you are given by the NSRI, SanParks, or whoever comes to take charge.

A free-swimming but entangled whale should be immediately reported to the NSRI as well – they will activate the South African Whale Disentanglement Network. Do not attempt to assist the whale yourself – this could be fatal for you (not the whale) – rather make a note of the direction it is swimming, and its precise location, and whatever other helpful information you can provide. Whale entanglements seem to be increasing in frequency around False Bay in particular, as more experimental fisheries are approved. (If this worries you, you could write a letter to DAFF about it.)
