Diving between tectonic plates
Underwater explorer and Suunto ambassador Jill Heinerth has dived in breathtaking locations all over the world so when she says one place has the clearest water and is the most inviting it’s worth sitting up and paying attention. It’s time to update your bucketlist. Located in Iceland’s Thingvellir National Park is the most impressive meeting place of the North American and Eurasian tectonic plates – the Silfra fissure. The two plates drift apart about 2 cm every year and snorkelers and divers can swim between them in the fissure and even touch the two continents at the same time – the only place in the world this is possible.
Intrepid underwater explorer, photographer and film maker Jill Heinerth dived there in 2014 with scientist Jónína Herdís Ólafsdóttir who is researching the unique bacterial colonies that live in the Silfra and in other fissure cracks around Iceland. The research may offer insights into early life on Earth and possibly about life on other planets. While exploring there, Jill captured some amazing images of Jónína swimming in the fissure. Prepare to be amazed.

100 m visibility
The underwater visibility in the Silfra fissure is over 100 m. This is because it’s cold (2°C – 4°C year round) glacial water that's filtered through lava for 30 to 100 years before seeping from underground wells into Thingvellir Lake. It’s so pure it’s fit to drink. “Diving or snorkeling in Silfra should be on everyone's bucket list,” Jill says. “There’s simply no other water on this planet that is as clear and inviting.” © IntoThePlanet.com – Jill Heinerth
Diving into creation
The Silfra fissure has four sections that can be explored: the Silfra Big Crack, the Silfra Hall, Silfra Cathedral, and Silfra Lagoon. “Drifting through the gap in the tectonic plates in the middle of this gusty, raw and primordial environment makes you feel like you are diving into creation itself,” Jill says.

Discovering the earth’s last hidden frontiers with Phil Short
Phil Short has been a dive industry professional for over 20 years. He has explored some of the world’s deepest dry caves and spent thousands of hours diving water filled passages. Research and archeology are also his passion, including such assignments as the Antikhytera survey project in Crete. But what is down there that draws Phil to explore these submerged realms?
Cave diving is the last field where human beings are mandatory for exploration. In Victorian times, when somebody climbed a mountain, that was it. They were the first. Now technology has taken over. You can take a look at a picture of a mountain, a valley, jungle, or a gorge before you go there. It has been all mapped.
“When you get to the end of the line in a cave, tie your line to that line and swim around the corner, you're the first human being there. It's true exploration, much like Shackleton, Scott and all of these early explorers did because there was no choice. In cave diving, there's still no choice, and that's why I’m so passionately driven by it. Anyone with a sensible budget can find new territory.”
THE CAVE DIVING ROCK NERD
Millions of years ago, the seas were filled with very different kinds of life forms than today. Over the millennia, soft seafloor turned into limestone, preserving a snapshot of these creatures from the past. Caves cut right through these ancient layers, displaying a rich collection of fossils and telling a geological story of the Earth’s past.
Phil Short has dived caves all over the world, spending thousands of hours diving exploring many kinds of dry and water filled passages. He knows that seemingly small details hide countless stories. Taking a close look, a bulge in the cave ceiling can turn out to be a tooth of an extinct tiger.
“Think about swimming through 100 metres of cave passage today, and memorise all of it. And then get into a time machine and go 3,000 years into the future. The cave would be different because you're diving in something that is alive. The acidic rainwater is dissolving rock, and the flow of the water is eroding it. So the cave is growing. It's forming. It's changing as you're swimming through it.”
SETTING THE PERSONAL LIMITS IN CAVE DIVING
Cave diving requires rigorous training and the right equipment. But there also needs to be the correct mentality and respect for the forces of nature. Constant practise and safety margins are the cave divers tools for keeping the risks at bay.
Phil Short has been a dive industry professional for over 20 years. He has trained hundreds of divers and participated in demanding cave rescue operations. With the experience of thousands of dives, he knows where to draw his line.
“I don't consider cave diving an adrenaline sport. In fact, it's the opposite. Going to an extremely deep point in the ocean, just to get a number for a depth record, that is not my motivation. I would happily do, and have done a lot of very deep dives, for a reason such as a historic shipwreck that nobody's managed to dive. I have more of a kind of Peter Pan, never grow up, child-like approach to exploration. Being there is just magical. It's my drive.”
GUIDING STAR – A YEAR OF UNDERWATER ADVENTURES
“There is something special about the connection between women that cannot be explained with words alone. It is that deep feeling of affinity we have that brings us close and sets a common understanding of what we experience in our life’s triumphs and tribulations. It is a connection only a woman can truly understand. That is what makes the Suunto Jewel so special. The very essence of its existence and what it represents, expresses that unspeakable bond that brings us together,” the Scuba Diver Girls say.
Last February, Suunto sent three Suunto Guiding Star pendants on a journey around the globe. The pendants were passed from one adventure-minded woman to the next, travelling from the Alps to the Arctic Lapland and onwards, and from the Pacific Ocean to icy waters in upstate New York and back under the Caribbean Sun.
We have been following the journey of one pendant in particular, as it was passed on among some of the world’s most inspirational female divers. Here is an account of that journey, told by the divers themselves. While the list of adventures and places the jewel has seen is impressive, what strikes as most extraordinary, is the invisible bond of sisterhood the jewel has created between these women.
The journey took off in the Maldives, where Scuba Diver Girls Margo Sanchez and Stephanie Adamson were the first women to wear the jewel. The jewel spent some memorable moments diving in the crystal blue waters around Maguhdhuvaa Island and later on travelled with Margo and Stephanie back home to San Diego, United States.
“The jewel came with us into our beautiful backyard, an ocean full of kelp, sharks, turtles and a myriad of other amazing sea creatures,” Margo describes. “After a few weeks of enjoying our precious piece of art, it was time to pass it along.”
Scuba Diver Girls chose to give the jewel to Becky Kagan Schott, the Emmy Award winning underwater videographer, photographer and tech dive instructor.
“Becky embodies an amazing spirit that every woman should embrace. We passed our jewel on, holding it tight as to pass on our energy with it. By now it has traveled the world and laid over so many strong women’s hearts. The energy it possesses is most certainly magical,” Margo writes now, looking back to that moment in February.
One of the strong women to hold the Guiding Star next was Jill Heinerth, the underwater photographer and film-maker specialized on demanding cave exploration and 3D imaging. She took the jewel on a National Geographic cave diving expedition in Cuba, where she conducted exploration and survey dives, working with climate scientists and paleontologists:
“My job was to photograph and video our work and also deploy an exciting 3D imaging technology. I was able to take numerous calibrated photographs that were assembled into a 3D model of some of the paleo animal artifacts inside the cave,” she explains. “These files were merged into an accurate model that could be printed in 3D so that scientists could examine and work with a model rather than disturbing the artifact underwater where is remains well preserved and untouched.”
During the months that followed, the Guiding Star traveled onwards to technical diver Renata Rojas, who in turn gave it to scuba diver and submersible pilot Erika Bergman, who handed the jewel to marine biologist, researcher and deep ocean explorer Megan Cook. In August, the jewel landed in the hands of the explorer, teacher and instructor Cristina Zenato, world renowned for her work with shark awareness and conservation. At the time she was in the Bahamas, hosting the Our World Underwater Scholarship Society’s scholar, teaching sustainable shark diving and shark conservation. Her work aims to change the economic situation of the Bahamians, enabling them to move from traditional fishing to different forms of work and income, including professional scuba diving.
During her time with the Guiding Star, Cristina also continued her long term project and conducted cave diving exploration in the area, successfully mapping and connecting previously undiscovered caves and water systems. “It has been a solo expedition and work and the jewel happened to be with me on the day I did the two most important ones. I consider it my luck charm,” Cristina concludes.
Cristina passed the Guiding Star on to technical diver Gemma Smith, the first woman ever to dive at the world famous Antikythera Shipwreck. Gemma took the jewel to Central France, to the Lot/Dordogne region, where she completed her internship and became an Introductory Cave Diving Instructor on Open and Closed Circuit and managed to log some long-awaited cave dives.
“I was also fortunate enough to complete a major cave diving personal ‘bucket list’ goal during the trip. I wore the Suunto Guiding Star to guide me 2.2 kilometers through the earth, reaching depths of up to 80m to finally reach the stunning cathedral-like Bivouac Chamber in the Emergence de Ressel,“ Gemma says.
The journey of the Suunto Guiding Star still continues and we wish every future woman to hold the jewel to get a spark of that energy and courage these women have passed on with the pendant.
“It has been an honor to carry the Star on such big moments in my diving journey, and I really hope I've inspired other women to follow their own diving dreams, and show that size and gender should never hold you back,” Gemma Smith summarizes.

What freedivers can learn from the top of the world
Suunto ambassador and freediver William Trubridge has given his life to the sport of diving as deep into the ocean’s depths as any human can without scuba equipment. But he recently decided to explore the other end of the planet – the heights of the Himayalas. He trekked 300 km, with 10,000 m of vertical ascent. The longest day was 13 hours of hiking. We asked him what he learned at the top of the world.
Why did you go trekking in Nepal? It was mainly to do something together with my father David and brother Sam, as we live in separate parts of the world. We chose the Himalayas, as my father loves the mountains, and neither Sam nor myself have seen those kinds of mountains.
"I think freediving training definitely has a crossover effect to mountain climbing."
Where were you?We trekked to Kanchenjunga base camp in eastern Nepal. Kanchenjunga is the third highest mountain in the world, and one of the holiest. The remoteness of this area means there are few trekkers and even fewer amenities. This is exactly what we wanted.
At 5163 m, the atmosphere is half as dense as at sea level, meaning half the volume of oxygen per breath.Vastly different environment than you’re used to – how was it? It was humbling. I realised just how un-adapted my body is to that kind of world. After 12 years of only freediving training in the water my knees were unacquainted with any kind of impact, and the first day's gruelling descent paid its toll. In fact, all the descents were tough for me. I really enjoyed going uphill because I was able to push myself. You’re used to having a lack of oxygen – how was the higher altitude for you? The altitude wasn't a factor. Our ascent was very gradual, which allowed the body time to adapt. I think freediving training definitely has a crossover effect to mountain climbing by developing haemoglobin oxygen storage in the blood. Freediving training stimulates erythropoiesis, which is the generation of new red blood cells, in order to store and transfer more oxygen. This benefits all hypoxic activities, whether apnea or trekking at altitude. What did you learn? It gave me an appreciation of volumes, and the vastness of the mountains, but also the seas. When looking up at a towering 7,000 m peak and thinking that huge mass could disappear in the huge well that is our planet's oceans it made me marvel at the scale of these environments. What can freedivers learn from trekking or the mountains? Trekking can be a kind of meditation, as the slow pace of changing scenery lulls your mind. It also gives you an appreciation for the 'other end of the spectrum' of our planet's ecosystem, and for the many other various forms that water can take: snow, rain, mist, waterfalls and rivers.

Diving the Shipwrecks of Bell Island
Suunto ambassador and underwater explorer Jill Heinerth dives the world's most incredible locations. Bell Island, Newfoundland is one such site. The video below shows why it's a diver's paradise.
Tell us about the Bell Island and its wrecks.
Bell Island is one of the few locations in North America that was under attack by German forces during the Second World War. In 1942, U-boats raided the island twice, sinking four iron ore carriers and destroying a loading wharf, killing more than 60 men. During the war, the mines on Bell Island, Newfoundland supplied iron ore that accounted for one-third of Canada's steel production. Germany knew that they could interrupt the flow of ore, even temporarily, and Canada's war output could be seriously affected.

What drew you to dive there?
I was part of a team documenting the recovery of a sextant from the wreck of the Rose Castle. Rick Stanley, owner of Ocean Quest Adventure Resort, worked for over a year to secure the correct permits and line up provincial conservators to preserve the important artifact that will be eventually be displayed in an extensive museum on Bell Island.
Why is it such an amazing dive location?
Newfoundland is a great destination for the adventurous divers. Today, divers visiting Newfoundland’s rich waters, can dive these remarkable wrecks that have transformed into stunning and colorful reef structures.
Is there more to explore there?
In the summer, divers can also enjoy diving on icebergs and swimming with whales that gather in the area to feed on capelin. I’ve been recently working with other cave divers to document the submerged mines which cover over 100 square kms. This coming season, mine operators hope to open diving activities to qualified cave divers visiting the area. The mine is still filled with all the equipment and artifacts of operations there. Seeing the large equipment, miner’s graffiti and personal items is an interesting opportunity.
