With the support of the Weston Foundation, Jill Heinerth visited Bairdmore School in Winnipeg to talk about exploration and science. Jill is on a cross-Canada speaking tour as the Royal Canadian Geographical Society’s Explorer in Residence. She shares a multimedia presentation about science and new career opportunities and works with small groups of kids on specific skills such as photography, career planning and research opportunities. Jill encourages kids to use discovery learning in their lives and teaches them that failure can have many unforeseen benefits for discovery and learning. She talks about risk assessment, fear, discovery and exploration in the context of geographic education.
The Weston Foundation in cooperation with the Royal Canadian Geographical Society is sending Jill Heinerth to schools across Canada. This week, the RCGS Explorer in Residence visited with kids in Saskatoon at Fairhaven School and Holliston Schools to talk about exploration, geography and future career opportunities. Kids were totally engaged in the presentation and were eager to ask questions about fear, underwater science and challenging gender norms. A small group of kids got a special treat, learning how to operate Jill’s professional cameras and spending the day as photo-journalists.
National Geographic Photo Editor Sadie Quarrier recently recognized 9 remarkable women for their skills as adventure photographers.
For female adventure photographers, it can also be a challenge to break into this male-dominated niche.”
Jill Heinerth was visiting Calgary to speak to school kids about exploration and geography. Students at Alice Jamieson Girls Academy, Stanley Jones School, Dr. Martha Cohen School and New Brighton School had a chance to meet Jill and hear her multimedia presentation about exploration and science. She met with small groups to coach interested kids in topics including journalism, photography, career planning, fear, failure and discovery learning.
Jill’s talks are made possible through support from the Weston Foundation.

Farewell to the Team
Most people who know me know of my military background. Navy diving was something I had aspired to since I was a child and being part of an elite team was something that I felt drawn to whole heartedly. I’ve always felt comfortable and most importantly, safe, when my peers and I functioned as a well-practiced crew, each person bringing their own expertise and talents to the table to efficiently reach our cumulative goal.
For last two weeks, a group of people diverse in talents, and varied in origins have conducted such efficient, expert and safety conscious efforts in association with our National Geographic Blue Holes Mapping and Educational Outreach program. Our assemblage of volunteers includes educators, explorers, technical experts, Bahamian NGO’s, government employees and of course, our students. We have all come together with a common goal of exposing the world the exquisite, rarely-seen part of our planet that exists right under our feet.
Although this December session was only two weeks long, the story behind the building of this team and the common goals for the protection of Abaco Caves go back more than 10 years. Working with the Bahamas National Trust, The Antiquities Monuments and Museums Corporation, Friends of the Environment, The Bahamas Caves Research Foundation, The University of Miami, The University of Florida, The Florida Natural History Museum and the Ministry of the Environment’s Forestry Department, the players in this team have worked hard to find common ground in conserving these irreplaceable, cultural treasures of the Bahamas.
In 2005, one of our team members, Dr. Kenny Broad, wrote our first exploration grant to The National Geographic Society. I was stunned when we received the great news that they felt our project was worthy of funding and promotion.
This was a major step in the team’s conservation efforts. With the support of The National Geographic Society, our diverse group has been validated. Such high-profile recognition of our efforts helped launch more grants, documentaries and magazine articles while countless images, posts and blogs within the cave diving world blanketed social media on the interwebs.
The Bahamian people are extremely proud of their heritage and culture. Blue Holes and underwater caves have long been steeped in mystery and Bahamian folklore. They have been culturally intertwined with the inhabitants of these islands both now and before Columbus made landfall.
The Crystal Caves of Abaco have been seen on television documentaries around the globe in multiple languages. We have demonstrated to governmental agencies that these sites are worth much more to the Bahamian people as they are now, than if they were exploited for other short term gain, commercial purposes. They truly represent the uniqueness, the timelessness and the unrivaled beauty of our small island nation.
Our basic goals were to map as much of the Crystal Caves of Abaco as possible, while getting our message out to as many students as possible, both locally and internationally. Mission accomplished!
But another important accomplishment was achieved. Two weeks ago, some of our team had never met. Others were long-time friends who had experienced some of the most exciting expeditions of our lives together. But from every part of this multi-faceted project, new friends were made, new professional associations were formed, new expeditions have been planned and most of all, we bonded as a team. The comradery created by our experiences during this effort will last a lifetime, from team leaders to students.
It is routine practice for conservation groups to paraphrase Baba Dioum, the Senegalese forestry engineer: “In the end we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught.”
But from the beginning, this project has been the embodiment of his words. From the original exploration, the recognition of this exceptional ecosystem that affects biodiversity and human health, and the efforts to share images and insights about these places locally and beyond, we proudly say again: mission accomplished!
It is with the deepest gratitude that I thank all the team members, both old and new. Individuals, agencies, and ministries who have been tenacious, both then and now. You all helped to bring the Crystal Caves of Abaco out of the darkness and into the hearts of the people of the world.
Tom Morris is a biologist and diver who lives in Gainesville, Florida and turned 70 years old on this expedition. His birthday present was a passport that he left in his car before heading across the Florida Straits by boat to join the team. He can now leave the Bahamas when the time comes, although he would rather remain in the Bahamas, where the pines sing, the bracken is tall, and every other plant is an aphrodisiac.
At its closest point, the Bahama Archipelago is a mere 50 miles from Florida, but it has virtually nothing in common with continental mainland animals, except for the ones that can fly (birds and bats). In fact, the only native land mammal found naturally in the Bahamas is the hutia, which is of South American origin. And there are only three species of snakes, all boas and probably descendants of a common ancestor, also of South American origin. The same pattern holds true for frogs and lizards, and even insects. So how is it that the archipelago is so biologically isolated from North America?
Some animal groups, notably the reptiles, with their waterproof skin and low metabolic rates, are able to survive relatively lengthy ocean crossings – think Galapagos and Seychelles Island tortoises and Komodo dragons. And I have personally seen diamondback rattlesnakes, which were at one time numerous on Florida’s barrier islands, floating miles out in both the Gulf of Mexico and the Atlantic Ocean, apparently none the worse for wear. But an animal floating or riding a log from Florida has to overcome two big obstacles to make it to the Bahamas; the trade winds and the Gulf Stream.
The trade winds are planetary winds, the largest and most consistent winds on earth, and the Bahamas lie directly in their path. The trades blow from an easterly direction over two-thirds of the time, pushing floating objects towards the mainland.
The wind blows from the west less than ten percent of the time. and is generally much weaker than the easterlies. But, even if favorable winds push a drifting animal towards the Bahamas, it will soon find itself in the Gulf Stream, and moving north at up to six miles per hour, toward the open Atlantic and almost certain death.
Animals and plants on islands have historical extinction rates far greater than their continental cousins. Everyone is familiar with the fate of many isolated island inhabitants, such as the flightless birds of New Zealand, who evolved in the absence of mammalian predators, and could not cope with human introduced rats, cats, pigs, and other animals. The Bahamian fauna face similar threats. The only animals I have seen dead on the Abaco roads have been cats and raccoons. Both invasive species are known to kill local animals, including the threatened Abaco parrot. And, perhaps more tragic, a scale insect from the mainland, brought in on Christmas trees from the mainland, are destroying the native Bahamian forests of Caicos Island.
But on a more positive note, the local newspaper, The Abaconian, reported today that a pregnant manatee from Florida, named Washburn, has been tracked crossing the Gulf Stream, and is now swimming in the waters of the northern Bahamas near Walker’s Cay (pronounced “key”). She arrived on Thanksgiving day. This is the same gal who was rescued from the cooling waters of Cape Cod, Massachusetts. Ain’t no trade winds or Gulf Stream gonna keep this girl from going where she wants to.

Sebastien Kister is a french cave diving instructor sharing his passion for the cenotes of the Riviera Maya in the Yucatan Penninsula with students from around the world. He applies his software engineer background in the development of software and measurement instruments aimed at making the underwater tasks of his fellow cave explorers and surveyors easier.
Planning the dive! Preparing the equipment, gearing up! Exploring underwater caves! Laying line! Diving, diving and diving again! Any cave diver is thrilled at the idea of any of those steps, the common parts of our underwater explorer life. But when it comes to surveying or mapping a cave, enthusiasm is not usually the first emotion that comes to our minds. Surveying Is a time consuming occupation that requires a high level of focus while it is done. It can only go wrong … between parallax errors while reading the compass, to errors in estimating or measuring the length of the line, to the too common errors done while recording the data on the slate. To make it worse, getting a quick visualization of the data requires mastering software that is far from user friendly for the average non-geeky cave diver.
These evils were the ones facing any good willing cave surveyor at the beginning of my professional cave instructor career in 2011. I decided to develop Ariane, a cave mapping solution, in an attempt to make surveying and mapping more accurate and user-friendly for cave divers. The software was initially tested in the field during the exploration of the Doggi cave system with the Q.D.T team in Mexico. This expedition collected nearly 20000 feet of data and allowed me to quickly tailor Ariane’s features to exactly what the cave explorers needed. After 5 years of work on Ariane, I have the satisfaction of seeing it used for mapping the caves in Abaco during this National Geographic project.
Having taken care of Charybdis, the software part of cave survey, only Scylla, the actual measurement of the line in the cave, was left. That’s where Mnemo comes in. The result of a year of development and testing, Mnemo is a small handheld device that records all the parameters necessary to survey a cave line: depth/Inclination, length of the line and azimuth. In order to not effect the safety and cave awareness of the diver, I designed Mnemo to require as little attention as possible from its user, the actual contrary of what traditional slate/compass survey requires. Mnemo slides along the cave line collecting this data, using only one cursor and easily visible colours to control and signal the survey events.
The second evil was thus taken care of: surveying a cave line is now (nearly) as easy as swimming along it! Some of the explorers were given the opportunity to test the unit here in Abaco. and the beginning section of Ralph’s cave was surveyed both by hand (by Brian Kakuk) and with MNemo (operated by Sebastien Kister) yielding only a 1.8% difference. During the time the survey was done by hand it could have been done 5 times with MNemo

Steve first visited the Bahamian island of Abaco in 2003 and has been making regular trips since then to explore and map the incredible Crystal Caves. In 2015 Steve and Brian Kakuk were able to complete a project years in the making by connecting Dan’s and Ralph’s Caves—two of the most beautiful and important caves on the island, and the caves that are the subject of our current survey project.
Expedition Blog 10 / Dec. 12 / By Steve Bogaerts
Today was my last day working on the National Geographic Abaco Blue Holes project. It has been a very rewarding experience both to work with this talented multidisciplinary team and to dive the amazing caves Crystal Caves of Abaco. As one of the original explorers of these caves, I am continually awed by the surpassing beauty Mother Nature can create. Unfortunately very few people will have the chance to experience the beauty of these caves firsthand. To be able to share that beauty and wonder with other people is one of our mains aims in this project.
One of the best ways we can do this is through cartography. Bringing back a map of your exploration allows other explorers and scientists to follow your path, to study and learn more, and most importantly to raise awareness of the need to protect and preserve this unique and fragile environment. Over the years many people have contributed to the exploration of the caves of the Bahamas, but unfortunately much of the mapping data remains missing or of poor quality.
During this expedition, we are starting a complete resurvey of Dan’s and Ralph’s Caves, which Brian Kakuk and I finally managed to connect together after many years of effort in 2015. The resulting connected system is properly known now as Dan’s Cave and is one of the longest island cave systems in the world. The area surrounding Dan’s Cave has moreover recently been designated a protected conservation area by the government of the Bahamas. Producing a complete map of the caves will help in these continued efforts to protect and preserve this unique and fragile natural wonder.
From this initial fix, every point at which the permanent guideline in the cave changes direction or depth must be fixed in place with a locking line wrap. Each one of these tie-offs becomes a survey station. The surveyor records the depth at each of these stations using a digital depth gauge and shoots the azimuth to the next survey station along the guideline using an orienteering compass. They then measure the distance between the stations using a fiberglass tape or knotted line.
All this information together with any important features or comments is recorded on an underwater slate. This basic information allows the survey team to create a “stick map,” or skeleton outline of the permanent guidelines installed in the cave passageways. This basic map can be further fleshed out by measuring the distance to the walls, floor and ceiling at every station and creating a cross-sectional sketch. Photos and video may also be recorded along with further geo-referencing at selected sites using a ground penetrating radar location tool called a “pinger.” All of this information is then downloaded to a computer survey program that creates a 3-D rendering of the cave with embedded links to photo and video of significant areas of interest.
Surveying an underwater cave is inherently limited by the amount of time that can be spent underwater on any one dive. This is further complicated in these particular caves by the saw-tooth dive profiles of the cave passageways (zig-zagging up and down), the need to surface slowly to allow for decompression, and the fragility of the highly decorated passages. In addition these caves are extremely complex with maze-like passageways that create a complex three-dimensional jigsaw puzzle of intersecting permanent guidelines. The desire to survey the cave accurately has to be balanced very carefully against the need to protect both the cave and the survey diver from any harm.
Having said all of that, it is a very satisfying feeling to return to base camp with full survey slates and to watch the cave map grow as you input the data and gain greater insight into the hydrology and geomorphology of the area. As the map has grown, so too has my desire to discover more of the secrets of the Crystal Caves of Abaco. I hope to be back soon to continue this journey of exploration and survey.
I have an odd business card. The title simply says, “Explorer.” In reality, I am the Explorer in Residence for the Royal Canadian Geographical Society, underwater photographer/cinematographer, writer, dive technology contractor, instructor and motivational speaker. In a nutshell, I do the creative things that help keep me underwater and most of the time, underground in water-filled caves. This hybrid career is an occupation that defies easy description and leaves me pinching myself every day with excitement over my rewarding work.
On this project I am reunited with friends with whom I have worked for over twenty years. It is a joy to be in the field with such a capable and effective team. We all fall into place and jump into roles that keep us extremely busy without too much direction. Whether you are washing the dishes, finding the next roll of toilet paper or blending life support gases, there is important work that keeps the expedition moving along. Everyone has to be a specialist of some sort but also a generalist who is motivated enough to see what needs to be done. Good teamwork means that everything runs smoothly and operations are safe and streamlined.
My specialty role involves capturing everything that happens with photos and video. That means I get to miss a few dishwashing sessions, but have a lot of tasks that need my constant attention. My day begins and ends with camera maintenance. Batteries need to be charged, dome ports polished, and O-rings, cleaned. Troubleshooting and making minor repairs are a constant issue. When you take cameras and lights underwater, things will go wrong and gear will get damaged regularly. I am running four separate cameras topside and three can be encased in waterproof, pressure-proof Aquatica housings. Each camera needs to record audio as well and without a sound guy on the team, I have to do my best to keep on top of that too.
When I hit the water I carry my life support equipment weighing approximately 150 pounds with an additional lighting kit of 45 pounds, camera strobes logging in at 22 pounds and two cameras that come to roughly 25 pounds. Each component is carefully weighted and trimmed so that it is relatively neutrally buoyant underwater. That means I have to push the mass through the water but not fight with the weight. Once I am submerged, my right brain fights with my left. I switch between video and still photography while monitoring life support swimming through an overhead environment. I also have to arrange a creative dance with my teammates and that is where the experience comes in. I am not able to talk to them, so we work on a combination of experience, telepathy and hand signals to orchestrate stunning pictures that tell the story of swimming through the veins of Mother Earth. On some television projects I have the luxury of underwater communications and a large support team, but this a raw, voluntary exploration. There is no budget beyond the reward of a job well done.
When I surface exhausted at the end of day, the job really begins. I rush back to our base camp, download footage and stills and start the editing process. Social media and news today is about relevance, so each evening we reach out to the world with a new expedition blog. We all take turns writing posts, but it is my role to create these short videos for you each night before I crawl into my hammock for a few hours sleep. I choose fun over polish in my edits and hope these simple nuggets of our work will bring you a little closer to understanding the life of an explorer. There isn’t a person on this team who would rather be anywhere else in the world right now. Whether we’re assembling activities for school kids, carrying equipment or surveying these stunning caves, we know we have the best job in the world.
