You need this: the Shark Spotters smartphone 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

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.

We are headed to the Tankwa Karoo for some star (and moon) gazing this weekend, so I won’t be launching. Will see you all next week!

Shark Spotters app

The Shark Spotters mobile app has been nominated for an award for best use of tech by an NGO, and your help with voting would be much appreciated by the team. Go here to vote. It’s a lot of multiple choice votes but five minutes of your time would mean a lot! You can find links to download the very useful Shark Spotters app here.

Hi divers

Weekend dive plans

Sunday: Early morning double tank dive, location to be confirmed

Conditions last weekend were pretty good. Not much wind or swell and decent visibility. The wind and swell for the weekend ahead look great with very little of either. False Bay, on the other hand, looks a little messy from some humping south easterly wind today.

The wind dies tomorrow and stays away for the weekend. I don’t doubt that both False Bay and the Atlantic will offer decent diving if you take the time to check before you choose. I plan to launch on Sunday as early as possible for a double tank dive somewhere clean. I have family arriving at midday from abroad and want to be done by then. If you are up for a early dive let me know and I will add you to the list.

Great news

The Shark Spotters mobile app is available – search for Shark Spotters in the Apple app store or Google Play store and download it for free!

Weekend dive plans

Saturday and Sunday: early launches (around 7 am), location to be confirmed

I am working through some student dives as we enter the final quarter of the year, so am planning launches for both Saturday and Sunday. They will likely be early double tank dives, around 7.00 am, because the wind is forecast to pick up later in the day. The location – Hout Bay or False Bay – will be confirmed tomorrow afternoon when it’s clear which of all the contradictory weather forecasts are accurate! Want to dive? Let me know.

Shark Spotters have been keeping bathers and surfers safe, and providing groundbreaking research on Cape Town’s white sharks, for over 10 years. They are currently developing a smartphone app that will provide information on sightings of sharks and other marine life, sea conditions, and other information pertinent to the Shark Spotters program.

The app will be available free of charge, but there are some development costs that have to be raised before it can be launched.

Newsletter: Diving 9 to 5

Hi divers

Weekend dive plans

Saturday: Shore dives at Long Beach

Sunday: Boat dives from Simon’s Town jetty at 10.00 to the wreck of the Brunswick and 12.30, site to be determined on the day

The cold front seems to have passed by and the second one that was meant to arrive tomorrow seems now to be giving us a miss. We had 40 mm of rain at home on Thursday, for which we are grateful. The break in the weather means there is a good chance some diving might happen this weekend!

I am going to shore dive on Saturday at Long Beach and launch on Sunday, the first dive being to the Brunswick, meeting on the jetty in Simon’s Town at 10.00am. The second dive will be at 12.30, the location weather and viz dependent.

If you want to dive, let me know!

Support Shark Spotters

Don’t forget to donate to help the Shark Spotters complete their beach info smartphone app! Also, there’s an auction and comedy evening (with Nik Rabinowitz!) at the Two Oceans Aquarium on Wednesday 27 July, also in aid of Shark Spotters’ research. There’s more information about the event here.

Newsletter: Wishing winter away

Hi divers

Weekend dive plans

Sunday: Boat dives from Simon’s Town jetty to Photographer’s Reef and Roman Rock OR shore dives at Long Beach

I know we are barely past the halfway mark of winter, but the last few warm and pleasant days have got me wishing summer was here.

Some swell and lots of south easterly wind are in the forecast for Saturday, so Sunday will be the better option for diving. We will aim for a later start to see how well False Bay fares during Saturday’s onslaught. If we decide to launch the boat it will be from the Simon’s Town Jetty at 9.30 and 12.00 and the most likely sites will be Photographer’s Reef and Roman Rock.

If the conditions aren’t boat-worthy on Sunday, we’ll shore dive at Long Beach.

An app for beach lovers

Shark Spotters, who do pioneering beach safety work and shark research in Cape Town, are crowdfunding a mobile app which will provide information on beach and surf conditions, shark and other marine animal sightings, and whether the Fish Hoek exclusion net is currently deployed. The app will be available free of charge. Watch this video for more information about the app, and give your support by donating here!

The NSRI SafeTRX app

At the beginning of this year, the NSRI launched the SafeTrx smartphone app. It is available in other countries, and the NSRI brought it to South Africa. I have been using it since February. It has taken a bit of getting used to with a few missteps on my part, but it now provides great peace of mind whenever I go out to sea. The app is a journey planner for boaters, with the capability of activating emergency contacts should you not return to port on time.

The app is available for iOS and Android systems. Skippers using the app can register a vessel (or more than one vessel) with the app (mine is Seahorse). You can provide a photo of the boat, its registration number, its radio call sign, and whether it has an emergency beacon (EPIRB or similar). When you depart for a trip, you select which vessel you are travelling in, how many passengers, what type of trip you’re doing (diving, cruising, safety, etc.), and an estimated time of arrival. You can also specify the route you’re taking by including waypoints on the trip map.

Once you’ve set up your journey, you can text it to your emergency contact(s). On your return to port, you re-open the app, close your journey, and have the option to text your emergency contacts again to let them know you’re home safely. These are screen shots from Clare’s phone showing the start and end of a trip with six people (including me) on board:

The SafeTrx app comes with a login to the SafeTrx website, which allows you to review your journeys online. You can actually see updates in real time; Clare took this screen shot from the website when I was out at Duiker Island in Hout Bay. When I started to return to Hout Bay harbour, the boat icon could be seen moving (jerkily) towards the harbour entrance.

The website information also allows you to evaluate the directness of the sea routes you follow, which is important when supporting open water swimmers, and gives useful statistics about how far you’ve travelled on the boat and for how long.

The first time I used the app, I didn’t set my ETA (estimated time of arrival) correctly, and left it on the default value, which is fifteen minutes after the current time. Not long after that time had elapsed, Clare (my emergency contact when she’s not on board) received a phonecall from Maritime Rescue stating that I was overdue and had she been in contact with me? She assured them that she had and that I was a first time user of the app, hence the mistake! We were extremely impressed by the speedy response, and glad to know that the system works so efficiently. Needless to say I have not made the same mistake again.

I encourage you to visit the NSRI website for more information about the use of the app, including download links. If you see me on the jetty and want to take a look at the app set up on my phone, please feel free to ask!

Google street view goes to the Antarctic

The ice-obsessed will rejoice with me at this (not at all recent, actually) news: Google has included a number of Antarctic destinations on street view. Destinations include Half Moon Island in the South Shetlands, South Georgia Island, where Sir Ernest Shackleton is buried, Robert Falcon Scott’s hut from his ill-fated 1912 expedition, Shackleton’s hut on Ross Island, an adélie penguin rookery at Cape Royds, the South Pole telescope, the ceremonial south pole, and a couple more on the Antarctic continent.

While we’re down in the Antarctic with Google, they have also provided an interactive map of Shackleton’s Endurance mission of 1914 that gives an excellent idea of the distances covered, and includes both recent and historical photographs.

The Antarctic imagery joins Google’s prior imaging of coral reefs in Australia and a view of the inside a ship.

It’ll be quite a long while (a lot of lottery plays!) before we can afford to go to the Antarctic, and the continent might be much changed by global warming by the time we get there, but in the mean time there’s Google…
