SWIMMING WITH THE POD

What is the likelihood of a tsunami hitting your favourite beach? Dr. Hannah Power, from University of Newcastle's School of Environmental and Life Sciences, conducts research on ocean waves, and recently published on the likelihood and consequences of a tsunami hitting Sydney Harbour. She has also developed the risk forecast for the Figure Eight Pool in Sydney's Royal National Park. This forecast examines the likelihood of being struck by large waves on your journey across the rock shelf.

Have you ever had the visibility in a swim drop to a few centimeters? Has it ever gone a bit brown? Perhaps you've ended up swimming through sewage!
This happened to Dr. Ian Wright in the 90s, and is likely to have happened to any ocean swimmer who was swimming off the coast of Sydney in that period. Ian is a keen ocean swimmer and a senior lecturer in the School of Science and Health at Western Sydney University, whose research interests include freshwater ecology, water chemistry and water pollution. We chatted about the poo problem at Sydney's beaches.

Scott Portelli is an acclaimed wildlife and underwater photographer, and has swum with whales and other magnificent creatures of the deep in some of the world's most exotic locations, like Antarctica, Tonga, the Falkland Islands and Norway. Among many other awards, Scott was awarded Wildlife Photographer of the Year in 2016, and he runs tours that you can join up with around the world to swim with whales.

During winter, you're probably familiar with human snot, but are you familiar with whale snot? Dr. Vanessa Pirotta is!
Vanessa is a marine biologist, naturalist and science communicator, and has been collecting snot from whale spouts using bespoke drones in order to understand whale health. She's collected viruses, bacteria and DNA from the snot, in a much less invasive way than other methods. She's also run whale watching tours, swum with whales in Tonga and observed them in Antarctica.

Last time we talked about stingers, we learnt some valuable insights - don't wee on them! Turns out, there may be some better solutions on the horizon. Associate Professor Greg Neely, from the School of Life and Environmental Sciences at the University of Sydney, has discovered an antidote to the sting of the most venomous creature on Earth -  the Australian box jellyfish.
Greg's antidote, discovered using CRISPR genome editing technology, blocks the symptoms within 15 minutes, and overlaps interestingly with research conducted into cholesterol. This means that the drug development may already be out there and we could see something in the hands of life-savers sooner rather than later.

Whether you are an experienced or aspiring ocean swimmer, if you are in Australia or New Zealand, you will visit oceanswims.com. Oceanswims.com handles the entries for the majority of organised swims in this part of the world, as well as being home to commentary, photos, witty banter, results and competitions.
Paul Ellercamp and Suanne Hunt are the ocean swimming doyens who run oceanswims.com and Ocean Swim Safaris, and we talked rather pleasantly over tea and macaroons about all things ocean swimming, including how the sport has grown over the last 20 years, technology changes, drafting, some of the characters of the sport, swimming around the world, and Paul's starring roll, with a former Prime Minister (another great Bob Hawke story), in the classic Australian TV soap A Country Practice.
See if you can hear the puppy sleeping in the background on Suanne's lap!

Dr Gary Greenberg is a scientist, author, teacher and photographer who combines his passion for art and science by exploring the hidden small-scale dimensions of nature. Gary has invented multiple high-definition, three-dimensional light microscopes (for which he has multiple US patents) and nowadays focuses his microscopes on common objects, such as grains of sand, flowers, and food. He's looked at sand from all round the Earth, but the funkiest sand he has examined is from the Moon. He's hoping he can get some Mars sand! You can identify a beach (or heavenly body) from its sand, which depends on the temperature, surf and erosion conditions and marine environment. 
You can see Gary's sand photography for yourself at sandgrains.com. And you might like to do some searching for the in vitro human pancreatic cancer cells he turned into the planet Kyrpton in the first Superman movie - the nuclei of the cells look like impact craters!

Ocean pools are a delight. I love swimming in them, and they are also quite often simply beautiful places to be. Dr. Marie-Louise McDermott has written a PhD on ocean pools (Wet, wild and convivial: past, present and future contributions of Australia’s ocean pools to surf, beach, pool and body cultures and recreational coasts) and runs a fantastic website dedicated to ocean pools, All into ocean pools inc.
I had a wonderful chat with Marie-Louise about her love of ocean pools, why Australia (and Sydney in particular) has such a rich tradition of them, and their influence on Australian life.

Swimming caps are a large source of ocean swimming waste. Often only once used, destined for land-fill or the ocean itself, events have not got a handle on to how to appropriately use them. And despite popular belief, they do not break down in the environment in any useful timeframe. They are important facets of ocean swimming safety so that swimmers can be seen in the water and in their racing waves, but at the end of each season, even mediocre swimmers like myself end up with a bag full of caps, never to be used again.
So, what can you do? I've been collecting caps for Recap over the last few summers to give them on to good causes. One of those places they go is Reverse Garbage, an organisation that saves materials from landfill and renews their value by making them available for reuse by families, students, artists and community groups. Each year, they take about 35 thousand cubic meters of waste for reuse, saving tonnes of raw material, energy and emissions.
I spoke with Kirsten Junor, Creative Director at Reverse Garbage, about what she does with the caps, what Reverse Garbage does in general, interspersed with all sorts of reuse/recycle discussion. We recorded in the pub - surely the best way to spend an afternoon recording a podcast - so occasionally the sound quality dips.
