How did you get involved? It’s actually a bit of a quirky story – I became involved in the effort’s to save the Hector and Maui dolphins during the attempt to be the first man to free dive 100m in free diving. We called it Project Hector because 100m is a ‘hectometer’ – and to raise awareness of what’s happening to Hector’s Dolphins. We did the project, and it was a huge success, but my dedication to the cause didn’t end – so I've kept on campaigning. How endangered are they? Extremely. There’s only about 7,500 left worldwide – down from a population of 29,000 in the seventies. The Maui’s Dolphin sub-species of Hector’s Dolphins is thought to have only about 50 left in the population. You’ve only had one chance to swim with them… I’ve swum with other dolphins in the wild many times – where I live in the Bahamas, you see the Atlantic Spotted Dolphins, and Bottle-nosed Dolphins as well. But the swim with the Hector’s Dolphins was a really magical experience. It was in early 2011 when I was in New Zealand, and went to a place close to Christchurch – only a short encounter. Five or ten minutes. But even that was something I’ll never forget. They’re the 'Mickey Mouse' of the cetaceans – the dorsal fin is shaped like Mickey’s ear. They're all soft curves with colored shapes, gray and white, all over the body. World champion freediver Will Trubridge wants to raise awareness to protect the endangered Hector’s Dolphins. It’s much different to swim with a dolphin than any other marine life, no? Or even terrestrial life. Alongside them, watching them and watching you, it’s very apparent from just the look in their eyes that they are aware of you, studying you, curious about you. It’s a look you don’t get from other animals even cats and dogs. Maybe some monkeys. They’re very present, very aware creatures. Being alongside that and encountering that is a very incredible experience. Any other marine life you’ve bumped into down below? All the interactions I’ve had with big marine life were dolphins, sharks and manta rays. I’ve never actually swum with whales yet, never had the opportunity! That’s something I’d like to do. I’ve been in the water when humpbacks were close, just haven’t spotted one. In my childhood was with a dubong – it’s like a manatee – in Vanuatu. We didn’t know about him, although he was quite famous – the locals had been feeding it for years, and it was living all alone in the harbor. We jumped in to go snorkeling, we almost got blown out of the water by a bus-sized hunk of flesh trying to mate with anything it found. As a kid that was quite intimidating! How can we help the fight to save them? The organization NABU is leading the fight to save the Hector’s Dolphin – the goal is a complete ban on trawling or gill nets in their habitats. But we are up against a very stubborn and short-sighted government.

It’s always a good idea to dive with a partner – they’re there to help if things get sticky, plus it’s a lot more fun. But we’re going to go out on a limb and say few are more fun than the colony of sea lions at North Rocks on Hornby Island, near Vancouver, Canada. Suunto ambassador Jill Heinerth fills us in on what it’s like to go underwater with one of nature’s cutest, coolest creatures. There was easily a couple hundred sea lions around The sea lion colony at Hornby Island is active, and has little fear of people. My dive happened to be right around the biggest herring spawn of the year, meaning they were all around waiting for a feast. Ones you see solo in the wild tend to be a lot more shy.  They just want to play… Of course, sea lions can be dangerous. I’m not saying you should go out and hug a sea lion – but if you happen to dive with this group you don’t have a choice. As soon as you’re in the water, they just want something to play with. They can come across as quite aggressive – they’ll nip at your suit, the top of your head, or tug on your wings, but they aren’t trying to injure you. I’ve had one put his full mouth on my dorm port – and another one yanked me up to the surface to play.  … but it’s on their terms When they’re done, they’ll just head back to the rocks to sunbathe.  These are ‘Stellar Sea Lions’ That’s actually the name of the breed. I saw a few California Sea Lions as well, but mostly Stellars.  It’s super obvious they’re super smart  When you dive with these sea lions, you get the perception that it’s all play. They’re very curious, and they’re very trainable. At the seaquarium, they train the sea lions to undergo all sorts of vetinerary procedures to keep them healthy.  That part of British Columbia is absolutely stunning  On this trip I was diving a wreck called Capilano. There’s so much to see underwater. Some of the best diving in the world! Nutrient rich water year round. Stunning wildlife. Plenty of wrecks.  We dove during a blizzard  Full white-out topside. Great visibility below. Sure, the water is cold, but the air above was even colder. If you’ve got the right gear it’s no big deal. One sea lion loved my Suunto Eon!  He kept tugging at my dive computer – at one point he even looked like he was checking out my dive stats. So maybe one day they’ll make a good diver partner anyways!    Diving offers a unique chance for humans to observe marine animals in their native environment.

It’s not suppose to hurt your ears When I was a kid I dreamed about diving, but my ears and sinuses screamed in pain – but when you take a Scuba class you learn to equalize naturally. Diving should never be painful. Your ears hurt because of the effects of pressure – the volume of air spaces within your body are compressed by water pressure over your head. You need to adjust that change with equalization. You’re not breathing what you breath on land Most people mistakenly assume there’s an oxygen tank on your back. You’re not breathing oxygen, you’re breathing what you’d breath on land, and that's 21% percent oxygen, 79% nitrogen and a few trace gasses – but it’s dried, filtered clean, and compressed. Technical divers may use exotic gasses like helium to conduct dives at much deeper levels, but recreational divers just breath, well, normal air.   How long can I stay under water, really? That’s a tough questions! There’s a lot of factors that limit your dive. Important ones being how much air is in your tank and how deep you go. Recreational divers generally can ascend to the surface at any time during their dive with no need for de-compression stops on the way. Uhhh, what are decompression stops? Technical divers have an artificial ‘ceiling’ over their heads (or sometimes a real one). Artificial ceilings are created when you go deep or very long, and your body needs to time climatize and release gasses that have accumulated in the body. If you go higher, faster, you could get injured – it’s called decompression sickness (colloquially known as 'the bends’) and trust me, you don’t want to deal with it – symptoms include joint pain, headaches, neurological damage, even paralysis. But let me be clear: this is totally, 100% avoidable. How safe is diving? Statistically, diving is incredibly safe if you’re following the rules and know what’s going on. You’re more likely to suffer a fatal bowling injury! But you need to follow the sea conditions and weather, and follow the basic safety rules you learned in dive class. Will my whole body wrinkle up like my fingers after too long in the pool? Ha! That’s great, but no. You won’t come out looking like a prune. What’s a dive algorithm? A dive algorithm is a complex mathematical formula that attempts to simulate how the human body deals with the inert gas in scuba diving on descent and during the dive. It predicts how the body will off-gas that same inert gas to allow us to find the proper schedule for a safe ascent back to the surface. See the above statement about ‘decompression stops’. Give us a sample dive profile? A ‘dive profile’ is basically a map of how deep you go when (and for how long) during a dive. A rec-diver going to 30m of depth has only of 20min of bottom time before they ascend back to the surface with no safety stops. Alternatively, tech divers will spends hours at 30m, using rebreathers and different gasses to complete that dive, and they’ll have a number of decompression stops to come back to the surface. Are there any long-term effects? The current algorithms keep us in the safe envelope of exposure. I’ve got 7,000 dives, and sometimes am on projects that extend for months, diving every single day. Researchers are still looking at us (by that I mean people like me!) to see if there’s any long term effects. Decompression stress – the same thing that astronauts deal with, just on lesser levels – is of great interest to physiologists – there’s a lot of questions about how that stress expresses itself on bones or tissue over very long periods of time. But I’m 52 years old, and can still swim circles around most 20 year olds, so I’m not too worried for the long run! Stay tuned for more articles about the science of diving.   READ MORE Explore a frozen world with Jill Heinerth How deep can we go?

Tell us about yourself: My name is Alex and I'm an American underwater photographer who's been working in Indonesia for the last four years. I live on a boat that splits seasons between Komodo, Raja Ampat, and the Banda Sea. I dive every day with my camera in the ocean's most diverse reefs and I love my job! Where do you like to dive? My work keeps me diving year round in Indonesia and you could say that I like Indonesia quite a bit. The diversity of species/subjects and of types of diving are endless. If you are feeling a bit burnt out on macro for example, it's not hard to find some wide-angle subjects like mantas, mangroves, or stunning reefscapes. It's where I've learned to take pictures and can't imagine a better training ground. What inspires you in the underwater world? I find myself most inspired by the underwater world by the fact that there is no experience on land where you can be so incredibly immersed in nature as you can be underwater. On land, not even the boldest photographer would be caught running around as a pride of lions hunts a heard of wildebeest. They'd be destroyed, either by the lions or by the stampede. Yet, underwater you can quite literally be in the middle of a feeding frenzy of the oceans top predators and come out without a scratch, and some pretty incredible images. As a photographer, those types of encounters are what you live for. How would you describe your photography style? Until I find that subject that I really want to focus my attention and time on, I'm sort of like a golden retriever who's found a ball, a stick and a cat at the same time. I want it all but can only choose one at a time. I'd say that my style is a bit eclectic, which I think also has a lot to do with the wide range of subjects in Indonesia. I love wide-angle and playing with natural light but I do love the hunt for those funny little benthic critters. Is there a story you wish to tell with your images? There's always a story to tell with your images, though I believe that story may be read differently depending on the viewer despite what I had intended to say with that image. I always want my images to reflect the beauty and fragility of nature. Hopefully some of that is getting though and maybe it even inspires some change in people’s perspective of the natural world and the need to preserve it.

Even if you’re just a casual diver, you’ve heard of Dean’s Blue Hole in the Bahamas. The deepest saltwater blue hole in the world, at over 200m, it’s a mecca for underwater adventures of any sort – from scuba divers to free divers. But what many don’t realize is the island nation is home to not only this natural wonder, but many more as well. The caves are referred to as the Abaco Blue Holes, it’s one of the most diverse and vast cave diving areas in the world – with many caves still unmapped. That’s precisely why Suunto diver Jill Heinerth will join an elite crew of divers in the Bahamas for a massive survey and documentation push on the Abaco Blue Holes. "I will be joining an elite crew of some of the finest cave diving explorers on the planet, lead by Dr. Kenny Broad, we will be joining Brian Kakuk of Bahamas Underground, and the Friends of the Environment in Abaco,” says Jill. The area is rich in dive history – her partners on the project have been exploring these caves for over two decades. You can make legendary dives through areas like Fangorn’s Forest in Dan’s Cave, or see artifacts such as 3,000-year-old crocodile skeletons in Sawmill Sink. Of course, diving here is with no small risk – as always with cave diving, the right equipment and a wealth of experience from at least someone on your team are absolute necessities. What’s the occasion for the study? "After over a decade of hard work, these blue holes have recently become protected within a newly designated national preserve,” Jill tells us. What’s even more interesting is that while this project is an underground operation, it isn’t undercover. They’ll be broadcasting almost live. “The team also has an aggressive outreach initiative that will include satellite transmissions to classrooms from the field and advanced 3D imaging efforts that will help to develop interactive resources that will help topside visitors get a sense of the beauty that resides beneath their feet.” Things they’ll see in the caves include stalactites and stalagmites formed by deposited calcium. They can be rich environments for marine life – Bahamas-based diver Brian Kakuk calls them ‘overstocked aquariums’ – and they hold unknown potential for research – and it’s big win for research. These caves have been important laboratories for climate change science and biological studies and their new added protection will undoubtedly offer many more opportunities for science. Follow along to see the Abaco Blue Holes project in action! Watch Jill Heinerth’s Expedition files on Youtube.   Get ready for hangouts by satellite: Virtual Field Trips to the Bahamas! This week a new BGAN unit (textbook sized device that allows video Google Hangouts from pretty much anywhere on the planet) will head by boat to Abaco in the Bahamas on a National Geographic Expedition with Kenny Broad and Jill Heinerth. The next hangout, an EBTSOYP Hangout, will be on December 8th @ 11am EST. Lots of camera spots available and you can check out a background hangout with Kenny and Jill here. >>Watch a replay of the Virtual Field Trip here<<   Read more about the project at intotheplanet.com

Last month, we sent Suunto #DiveWithMe winners Anna Starup and Theresa Thorp to the Philippines for a little dive adventure in paradise at Atmosphere Dive Resort – suffice it to say the girls enjoyed themselves. Now that they are answering e-mails again (because let’s be honest, we wouldn’t be answering e-mails on a dive vacation either) we pinged them with a few questions about the trip – and of course, got some pics. Anna, this was a learning experience for you. Anna: Yeah – I did my final certification in the Philippines after preparing at home in Denmark using online courses. Diving just caught me right away. In retrospect I’ve thought about why I didn’t take my open water earlier. Diving is definitely going to take me (and Theresa) to places in the world I’d never considered before. Best single dive of the trip? Anna & Theresa: That’s actually quite a hard question! The dive sites differed a lot and each had amazing aspects about them. Perhaps a dive at Apo Island where we saw a dozen turtles that played around with us. Or a dive where a blue-ringed octopus saw its reflection in Anna’s dive instructor’s camera and attacked it! At the same dive we saw 4 species of Octopus’ and a lot of cool frogfishes. Of course, you didn’t spend every moment on the boat… Anna & Theresa: Atmosphere quite is a little piece of paradise. Rooms, dining area, dive shop, beach – just amazing. We’ll have to mention the food here as well. Besides diving, eating was definitely a highlight every day! The people at Atmosphere were a huge part of the amazing experience we had. Everyone seemed like a little family, joking around, stopping for a chat, taking interest in each other’s (and our) lives. You made such good friends, you even got a nickname… Anna & Theresa: Someone from the dive crew, jealous of our cool Suunto D4i, nicknamed us “The Suunto Girls”, which kind of stuck to us for the whole trip. Not the worst nickname, right? We also have to send a special “thanks” to Ulrika, Marco and Daniel from the Atmosphere family, who were the main reasons why this trip became such an irreplaceable and spectacular adventure. We’re still feeling completely and utterly high on life, thank you! And you even got into the jungle! Anna & Theresa: On our way to the resort we met up with Theresa's brother and friend who is currently backpacking their way around Asia. We woke up at 5AM for a short jungle hike which led us to the most stunningly beautiful, lagoon called Kawasan Falls. Being there early meant having the waterfall all to ourselves for hours! A ton of fun swimming, cliff jumping and playing around in the lagoon before we continued on our journey to Atmosphere Resort. We also got to explore the Chocolate Hills, joined a dinner cruise at Loboc River, saw the Tarsier Sanctuary at Bohol Island, and visited Osmena Peak, the highest peak at Cebu Island. All spectacular sights and irreplaceable small adventures. Do you feel more confident underwater? Theresa: Getting to share the incredible underwater world with Anna for the first time was magical! We had so much fun during her Open Water Course, and later during our fun dives. Anna: I had studied quite a lot of theory, but all of it made sense when I got to try it in the water. I wasn’t sure how much I was going to remember if a situation occurred where I actually needed it, but during my very first dive for instance, my mouthpiece came off. Without knowing exactly what was going on, I just grabbed my reserve. So I think some of the exercises “internalizes” pretty fast. Can you name some of your favorite spots for future visitors? Anna & Theresa: The "turtle" divesite at Apo Island was called Rockpoint West. The divesite where we met the blue-ringed octopus was called Secret Garden although we called it Octopus' garden, as we saw a lot of octopus there. The whaleshark spot was called Oslob. Are the Philippines as a must-go dive destination? Theresa: Absolutely – especially if you're into muck and micro diving. It caught me right away, and I'm still in awe that critters, like the one we met, actually exist in real life! I was especially fascinated by the many different species of frogfish, nudibranch and mantis shrimp. Would you go back? Theresa: Definitely! The amazing dive sites and spectacular nature are sure to drag us back, and besides, we need to reunite with the amazing crew at Atmosphere Resort. What other spots in the world are next on your must-dive list? Theresa: Since this was my first time diving in Asia, I'll have to get back to explore some more! Right now places like Komodo, the Gili islands and the Maldives is on the top of my must-dive list. Galapagos has also been on the top of my list for quite some time now.
