RAD KI At Research and Discovery Coastal Tours Kangaroo Island (RAD KI), we offer a unique opportunity to explore Kangaroo Island's North Western coastline.
(1)

Our tours are tailored for those who share a passion for the marine environment. We welcome you to join us on our versatile 8m zodiac rib RADIKAL to explore the unexplored and to expect the unexpected! We will ferry you out to RADIKAL in our tender vessel from Stokes Bay boat ramp. This is where your adventure begins. After getting you all on board, we will head out wide in the search of various dolphin species, attempting to capture images of their dorsal fins for cataloging before heading back into the geological wonderland that compromises the far North West coastline of KI. RAD KI holds a permit to join sealion, seals and dolphins in the water. So if you are keen and the weather permits, we will seek out a sheltered cove and pop you into the water (with an underwater camera if you have one) to survey the incredible diversity of creatures, large and small, that we often encounter. Of specific interest are of course our at risk marine species such as the endangered Australian Sealion, the near threatened Leafy Seadragon and the vulnerable Western Blue Groper. But with 85% endemism of species in this little-explored section of our temperate Great Southern Reef, so much remains yet to be discovered, so who knows what you might come across. Not keen to hop in, no worries! There is just so much to see and do on the surface. We are actively monitoring the coastal raptors such as the ever-decreasing osprey population and the majestic white bellied sea eagles that nest along this coastline. You will no doubt also encounter many a pinniped (seal or sea lion) perched up on the rocky cliff face and may even observe the feeding frenzies of multiple species unfold causing havoc to the schools of small fish below. Never a dull moment, and always so much to record and see! And if you wish to just sit back and savor the journey, that's great too. We are happy to take care of the surveying for the day ourselves....and have you just feast you eyes on all that this incredible coastline has to offer whilst you just relax and enjoy. Following a fun filled morning we will indulge you in a mouthwatering lunch featuring all of Kangaroo Island's best local produce. From the delicious Stokes Bay smoked chicken, olives and sticky figs to the scrumptious D'Estrees Bakery rolls... there will be something for everyone in our bento box assortment of goodies. And naturally home made treats baked with KI's award winning local honey will accompany a hot cup of coffee or tea after underwater surveying. On our way home we will show you some of the most incredible geological wonders you have yet to see (promise!), and are happy to stop off at pristine inaccessible beaches on the way. But naturally if we come across a friendly pod of bottlenose dolphins, you may just feel that hoping into the water with them....or simply dropping down our hydrophone to hear what they have to say to us!...may take precedence over this. They are just so curious and playful. We have no itinerary per se. Every day is different. We let nature guide us from the very first moment you set foot on the boat. But we will aim to have you back within 5 to 6 hours of departure. At RAD KI we aim to discover the undiscovered with you. We aim to find out, through continual surveying, what is actually going on out there. And most importantly perhaps, we want you to be a part of this exciting journey of research and discovery with us. Who knows - you may well be the one to come across a whole new species! Give us a call. We can't wait to have you on board as fellow citizen scientist in this truly unique, exciting and just so incredibly beautiful part of the world. See you soon on RADIKAL! As a fully surveyed diving and research vessel we welcome any groups that wish to charter our vessel for this purpose only. Personal private charters very welcome also.

Back home on KI soon, but thought you might enjoy this short clip of an incredible swim I just had here in Tonga with feeding pilot whales and a curious shark.

It jumped in from our boat and was blessed with this incredible encounter. Just me and them. So special.

Sound up! Very vocal.

Three minutes of blis just 'hanging out' with our incredible short beaked common dolphins friends...

We interact with this stunning species on almost every tour or ocean outing.

Knowing that they too can contract, and have now contracted, the horrific bird flu is just unimaginable to this dolphinaholic.....

These guys are family to me.

*volume up - these guys are so very vocal!

Today it became personal.

H5N1 bird flu has been confirmed in a common dolphin found dead at Goolwa—the town where I grew up. It is the first confirmed case in a dolphin in Australia.

RAD KI has been following H5 closely, but we have said very little publicly. After a year spent documenting the devastation caused by the algal bloom, it has been difficult to find the words to speak about yet another threat to the wildlife and coastline we love so dearly.

But we are ready to speak again. As we did throughout the algal bloom, we will share what we see honestly and factually, and do our best to keep Kangaroo Island informed.

The thought of what may lie ahead is unimaginable. We wish this work were not necessary, but in times of such ecological distress, we must do everything we can to help build a scientific understanding of what is happening.

RAD KI will continue to contribute everything we can.

Rigorous citizen science is becoming increasingly important in these trying times.

Scientists and authorities are increasingly calling for help from citizen scientists to track species and changes.

DEW’s Marine Science Team, in partnership with Parks Australia, South Australian Research and Development Institute (SARDI), Flinders University and Deakin University, recently headed deep into uncharted waters to undercover one of Australia’s most remote, and least understood, marine environments – The Great Australian Bight.

The Great Australian Bight is vast, covering an area twice the size of Victoria and stretches from depths of 50 metres near coastal cliffs to up to abyssal depths of 5000 meters offshore. This dynamic and sometimes harsh environment is characterised with rough weather and an average swell of four metres.

Using underwater cameras and environmental DNA sampling, the team documented the remarkable species and habitats found within protected marine parks.

Early findings include previously unmapped reefs, sponge-dominated habitats and an abundance of sharks and rays. Researchers also tagged six great white sharks to better understand their movements.

Each camera deployment and water sample will help fill important knowledge gaps, giving scientists a clearer picture of life in the Bight and how it can be better protected.

Have you ever wondered how scientists, observers, hunters, and recreational whale watchers recognise different whale species from far away?

Well, there are many different methods of identifying different cetacean (whale, dolphin, and porpoise) species. We talked about one of them before—photo ID of humpback whales based on the uniqueness of their tail fluke. But there are many more methods of identification.

In the illustration you can see features that can help identify large cetaceans:
🐳 The position of the blowhole changes the way water spouts in different species, so that is one of the identifying characteristics. In s***m whales, for instance, the “blow” is aimed forward instead of upward.
🐬 Next is the way the animal surfaces for air. Some species only show a small part of their back or dorsal fin at a time, while others surface their entire body or even jump out of the water.
🐋 Some species are more likely to show their tails when diving, such as humpback or s***m whales, while some other species never do.

So the next time you are out at sea, keep your eyes open, and if you spot a whale, try to identify the species! In the meantime, make sure to read up on different species that live in the North Atlantic: https://nammco.no/whales-dolphins-and-porpoises/.
