Partnering with TerraMar


Individually, we are one drop. Together, we are an ocean. – R. Satoro

In the beginning we were only some freedivers and a few scientists in the middle of the open ocean, searching for sharks. Now, we are by no means a huge organization, but we have strong and experienced expedition team, and work with scientists around the world. At the essence of it all? Teamwork.

You probably know of bigger organizations. Some focus on working with politicians, others focus on educating children, as for us we focus on field work. Although we have different approaches and tasks, sometimes we find common ways to have an impact.

Therefore we have partnered up with The TerraMar Project to share our expedition experiences with a larger audience! We all have Twitter, Facebook and nowadays read hundreds of posts everyday. If you are after ocean news and articles with real foundation and engaging topics, make sure you go to http://theterramarproject.org/ and read the The Daily Catch for which we will hopefully contribute in the future.

A home away from home

In previous years we waited for sharks to approach the boat, started observing their behavior before getting in the water and beginning to place tags. This time around we packed our gear, loaded everything on Dr. Mauricio Hoyos’ boat and following some warm handshakes landed at the rocky beach of the north east cove and set up camp. Ahead laid 4 weeks of living and working on and around the island of white sharks – Isla de Guadalupe.

Base camp: an old fishing house

Base camp: an old fishing house



The old fishing house that Dr. Hoyos cleaned and improved over the years served as our base camp and provided shelter for gear and equipment. Camp life included no running water or electricity. Our diet consisted of hot tea, dry food, some apples and lemons throughout our stay – all cooked on a propane stove. Sometimes this was complemented by dinners on some of the cage diving boats that visited the bay.

Sharks and El Niño

In the beginning phase, working conditions in the water were very poor. The visibility was just over 10 meters with lots of particles in the water. In addition water temperature was a lot warmer than usual and caused sharks to stay deep. Once they arrived at the surface, most of them circled the boat a couple of times and disappeared again. The reason for these difficult conditions is the El Nino event that has been affecting many ecosystems along the Californian coast this year. Adapting to the poor conditions our freedivers had to stay very close to Dr. Hoyos’ boat and constantly look for sharks to not miss an opportunity to tag one.

The initial water conditions were more difficult than usually, with fewer sharks near the surface and a poor visibility

Since the sharks were shy and conditions difficult our Watermen spent lots of time in the boat waiting for something to happen.

More that meets the eye

But at a productive ecosystem like Guadalupe there is always something to see and explore. Amongst other things we got to see blue whales cruising through the bay, huge yellow fin tuna jumping in a feeding frenzy and dolphins keeping our sharks away from the boat. Guadalupe is probably the best place in the world to observe the elusive beaked whale. We got to see them on a daily basis in pods of 5-6 animals. Dr. Hoyos has had the chance of seeing them underwater and documented white shark bite marks on them. From our top water observations this season we can clearly say that Guadalupe isn’t just about the white sharks. This was further proven to us when we explored the coastline in order to find sharks that were searching for prey in the shallower waters around the island. It was an impressive sight to fin through the water, right under the volcanic cliffs, constantly keeping a look out for white sharks. Of course we had our tagging gun, biopsy gun, camera, and tags with us in case we encountered a good candidate for an acoustic tag.

Exploring Guadalupe

During these explorations we saw turtles on every single dive, big yellowtails, california sea lions, guadalupe fur seals, groupers, lots of reef fish, bat rays and horn sharks. It is such a diverse and productive ecosystem with an incredible scenery. When diving at a ridge to the north of the bay we crossed a 12-meter deep canyon when one of us spotted a 5-meter female Great White Shark cruising in on the bottom from behind us, passing under us and swimming away, with the gigantic caudal fin generating a powerful thrust against the current. It was an amazing sight to see a great white shark swim in between the rocky canyons and pinnacles close to shore and perfectly camouflaged to the sea floor.

So much to see

After finishing our work in the water and returning to camp we got to enjoy the company of elephant seals and Guadalupe fur seals at the beach. Being based on land and spending as much time on sight was a perfect opportunity for us to observe the pinnipeds’ behavior and their role in the ecosystem of the white sharks. Surprisingly, the most common cause of death in the Guadalupe fur seal population is not white shark predation but falling rocks. At several occasions we heard loud growls howling from hundreds of meters away when huge rocks crash down onto the shoreline or into the water. At first, the little fur seals were scared of us but over the course of the expedition they accepted us at the beach and became so confident as to sniff our feet and bark at us from a couple of feet away.

Surprise encounters

To engage people that are passionate about the ocean we gave presentations about our work at the cage diving boats that visited the area to show their clients the great white sharks of Guadalupe. Together with Dr. Hoyos who explained key aspects and findings of his research, we showed people that great white sharks can be interacted with and tagged by freedivers without a cage, but that these animals are still big ocean predators and have to be treated as such – with respect.

We are grateful for the many passionate questions and talks after our presentations and how much interest the people we encountered expressed towards ocean conservation and our work. We were extremely lucky to meet Dr. Sylvia Earle and spend an exceptional evening with her, friends and colleagues. It was one of the strangest feelings to ride a small zodiac through the dark waters around the cliffs of Guadalupe back to the camp with the only light being the stars – after having had lots of good company and a nice dinner.

Exploring Guadalupe Island without fins

Being based on the island also gave our team the rare opportunity to explore the island on foot. We prepared our backpacks and put our shoes on for the first time during our stay to find our path up an old dirt road. It didn’t take us long to understand how treacherous this terrain is. Rocks falling down the steep ridges and remains of vehicles from past accidents definitely left their impression on us. The island was unusually green in comparison to past expeditions. This was due to the many storms and hurricanes in 2014 which caused so much rain that it (in the right light) reminded us of the Azores. Cactus plants were to be found everywhere and penetrated our soles from time to time. When reaching the viewpoint from where you look across the entire bay, the sight was breathtaking. The contrast between the dark blue water, green murky patches in shore and the grey-red-orange walls of the island has something special. We spotted sea lions, elephant seals and beaked whales from up there. Once more, our team got to get a more lateral picture of the ecosystem and the role of the white shark at Guadalupe.

Mission accomplished

Over the course of the expedition conditions improved and even came back to “Guadalupe standards” by the end of the last week. During the last days of the expedition we placed more acoustic tags than in the weeks before because conditions went back to normal with 25-meter visibility, water cooled down and fewer particles. In total our team placed 15 acoustic tags and took 7 biopsy samples. Dr. Hoyos and Dr. Papastamatiou are excited about the outcome of the expedition given the extremely difficult circumstances under which our team operated this year. In addition to the usual acoustic tags we place on white sharks for Dr. Hoyos we placed new acoustic tags that have the potential to uncover interactions between Great White Sharks from Guadalupe and sharks from California.

When conditions improved the white sharks became more confident and moreover arrived at the surface again to check us out. Dr. Hoyos believes that the sharks at Guadalupe stay below the thermocline most of the time. The warm water of this year’s season pushed the thermocline deeper and therefore we were seeing sharks much less frequently at the surface. When in the water with the amazing predators in order to tag them, sometimes sharks that are already tagged come back right after or a couple of days later. This is a great opportunity to capture photos for identification purposes and the respectful interactions professional freedivers can have with great white sharks.

New Video on Great White Shark Tagging

In 2012, the team of The Watermen Project embarked on an expedition to Isla de Guadalupe, Mexico. For shark scientist Dr. Mauricio Hoyos, William Winram and Fred Buyle placed 11 acoustic tags on Great White Sharks in order to further study their migratory behavior.

The goal of these studies is to understand long-term movements of Carcharodon carcharias to propose science-based conservation and management plans.

Attending IMPAC3 in Marseille

Project type: Congress, Public speaking, Workshop
Dates: October 21-25, 2013
Location: Pharo Palace, Marseille, France
Project target: THE WATERMEN PROJECT to be introduced at the 3rd International Marine Protected Areas Congress; To share breath-hold diving key advantages for ocean observation/conservation
Team: William Winram, Michèle Monico
Participants to congress: > 2000


THE WATERMEN PROJECT will participate to its first international congress on the subject of Marine Protected Areas.

It will be a unique opportunity to meet with scientists from around the world, hear what progress have been made in the realm of Marine Protected Areas research and management as well as targeting challenges for the future.

Among the highlights of the event: IMPAC3 Ambassador Sylvia Earle, Oceanographer, former Chief Scientist of the US National Oceanographic and Atmospheric Administration, and now Explorer-in-Residence with the National Geographic Society. Dr. Earle’s message is about catalyzing action for ocean Protection. In cooperation with Dan Laffoley (IUCN WCPA-marine), she will launch a map showing 50 new Hope Spots: areas in the ocean that merit immediate protection for their value to ocean ecosystems and to humankind. Panel speakers will then present their progress on specific Hope Spot locations, from the Sargasso Sea to the Arctic, and Google Earth will demonstrate their latest technology to increase awareness and action for Hope Spots.

As IUCN Global Marine & Polar MPP Oceans Ambassador William Winram will participate to two events:

A workshop titled “Underwater observation techniques to support MPA creation and management” (WS2E2); 11:45 AM – 1:15 PM in NOTRE DAME room of the Pharo Palace.

Chairpersons: Dominique PELLETIER, IFREMER ; Renata FERRARI, University of Sydney

Contributors: Vincent MARAN, French Federation for Underwater Studies and Sports ; Patrice PLA, ACSA-ALCEN ; William WINRAM, The Watermen Project ; Dorothée COULOMB, ACSA

Observing marine animals within their habitat is probably the best way to understand their behaviour and interactions. Many underwater observation techniques are available, from breath-hold or scuba diving, to high technology fixed devices and autonomous vehicles. However, beyond the magnificent images of a largely unknown world, how can these observations help in preserving marine species and their environment? This workshop will first draw a panel of various observation techniques through a contrasted selection of underwater studies. A discussion will follow on how these techniques can complement each other for the benefit of marine life preservation. In particular, practical recommendations will be proposed, in terms of Marine Protected Areas management and public involvement.

Additionnaly, William Winram will present Great White Shark, on Thursday Oct 24 in the Auditorium.

“Our mission is to change people’s attitudes toward the great white,” says Steve McNicholas, co-director of the film. “It’s not the menacing, evil predator it’s made out to be. It’s simply performing its crucial role at the top of the ocean’s food chain. Great whites are not monsters any more than the polar bears or lions.” Great White Shark is a new IMAX film which launched in May 2013 in the U.S. and Canada and is now playing worldwide. The version shown during IMPAC3 is 2D digital. World champion breath-hold diver and IUCN Oceans Ambassador William Winram is seen freediving with great white sharks in the crystal clear waters of Guadalupe, Mexico, together with colleague Fred Buyle, for Dr. Edgar Mauricio Hoyos Padilla’s ongoing research.

Organized in partnership with the department of sports of the City of Geneva and the Museum of Natural History, this edition was officially launched with a special event organized on Saturday February 2nd.
William Winram introduced shark tagging to the audience with The Watermen Project’s first film titled Diving with Sharks, an 18-minute short which documented shark expeditions between 2009 and 2013 in the Mexican Pacific Ocean. In fact, the latest expedition was just finished mid January 2013 leaving only less than three weeks to edit the film for the premiere at the Museum.

Over 250 people turned up for the showing, some of whom could not watch the film because the auditorium had filled beyond its capacity. After the film, William graciously answered questions from the crowd of all ages, in the company of Laurent Egli, the film director and cameraman for the latter images of the documentary. The Q&A session lasted for over an hour.
