THE TUAMOTU ARCHIPELAGO

The Tuamotu Archipelago - population of 15,000 people -, an area threatened by climate change and rising waters, contains 78 atolls spread across an 800,000-square-kilometer ocean surface. It has 800 square kilometers of land for 20,000 square kilometers of lagoon - 0.1% and 2% of its maritime area respectively -, demonstrating how fragile this oasis of aquatic biodiversity is. The Tuamotu atolls are characterized by their height, shape, exposure to the ocean, population, and the activities performed there. There are small, closed lagoons, both hypersaline and brackish, and large lagoons open to the ocean like Fakarava, which features the largest pass in French Polynesia at 1,600 meters, and even a raised coral atoll, Makatea. Coral growth, which allows these small island reefs of only a few meters in altitude to exist, is directly affected by the slow and irreversible acidification of the oceans - a 30% increase over two and a half centuries. Here, as anywhere else, ecosystems are defenseless against commercial, demographic, and climate pressures. Here, more than anywhere else, the status of the marine mammal populations is largely unknown.

RANGIROA ATOLL

Yet 350 kilometers from Tahiti in the northwest Tuamotu Islands, the giant atoll of Rangiroa - ‘Great Sky’ in Paumotu -, a true oasis of life and diversity in the heart of the tropical Pacific, stretches its 170 kilometers of coral reefs, sands, and coconut trees around a 1,600-square-kilometer area with waters so fish-laden that it has become one of the world's top diving destinations. The atoll's impressive size - 80 kilometers long by 20 kilometers wide on average - and its two large passes, Avatoru and Tiputa, make it home to marine wildlife as exceptional as it is impressive.

THE NGO

Dolphins of Rangiroa - DOR - is a French Polynesian NGO dedicated to research, citizen science, conservation, education, and information sharing on Rangiroa common bottlenose dolphins (Tursiops truncatus) in the Tuamotu Islands, French Polynesia.

Born in 2019, DOR benefits from a 10-year scientific monitoring experience on Rangiroa bottlenose dolphins and a 8-year experience with ecovolunteers from all over the world who join us every year to help the NGO complete its field missions in partnership with Objectif Sciences International.

We focus our work on 1. The demographic and social monitoring of the bottlenose dolphin community inhabiting Tiputa waters, on the northern part of Rangiroa atoll, and 2. A better understanding of the behavioral changes observed in these animals as part of their interactions with diving tourism. We are thus interested in each of the dolphins’ history and personality.

THE COMMON BOTTLENOSE DOLPHIN

The common bottlenose dolphin, Tursiops truncatus, is distributed throughout the five Polynesian archipelagoes. However, the species is most regularly seen in Rangiroa atoll than in other Polynesian islands. In French Polynesia, adults can reach up to 3.5 meters and weigh up to 400 kilos. They are easily identified by their stocky and grayish body prolongated by a thick rostrum. The line of their mouth, curved upwards, gives them a ‘smiling’ appearance. Nevertheless, this morphological feature does not reflect the overall species’ behaviors as these dolphins have an extremely complex social life and may display affiliative behaviors such as play and petting as well as agonistic ones - e.g. intimidation, aggression. The numerous marks, notches and scars visible on the adult males’ bodies perfectly illustrate these animals’ strength.

RANGIROA DOLPHINS AND THE DIVING TOURISM ISSUE

Since 2009, DOR's scientific director has been studying the bottlenose dolphin community inhabiting the northern part of Rangiroa atoll. Her work mainly focuses on the impacts of tourist activities on the dolphins’ behavior. Indeed, these animals are targeted daily by commercial and non commercial ‘dolphin watching’ activities. Literature and the media have endowed cetaceans with a reputation that predisposes people to expect friendly interactions with free-ranging dolphins. Theme parks and aquaria, where people can touch, feed and swim with captive dolphins, enhance this reputation.

The popularity of marine mammal viewing activities can result in conservation and socioeconomic benefits for the animals and local communities alike if they are conducted responsibly and with care, in accordance with existing regulations that protect these iconic species. However, if viewing activities are not conducted appropriately, they can place marine mammals at significant risk of harassment, injury or death.

Some of Rangiroa dolphins have been conditioned on the medium to long term to tolerate or even seek out physical contact with scuba divers and snorkellers. Such a situation raises concerns about the risks related to unmanaged interactions between humans and wild dolphins. These risks include:

1. An increase in the number of diving accidents through, for example, ‘pushy’ behaviours or intimidation attempts from the dolphins and / or divers forgetting basic diving safety rules;

2. Disease transmission from dolphins to humans and vice versa;

3. An increase in the vulnerability to human activities of dolphins which have become too familiar - reduced avoidance responses to hazardous situations -, resulting in collisions with boats, propeller injuries, fishing gear entanglement, etc.;

4. Reduced overall behavioural repertoires, compromising ‘wildness’;

5. Changes in ranging and social patterns;

6. The implementation of an ‘open water dolphinarium’ situation lacking basic educational components.

OUR GOALS

For many years, divers and snorkellers have encouraged physical contact with bottlenose dolphins - especially young individuals - on the Tiputa area. This situation has made some dolphins familiar with humans, putting them particularly at risk within the context of anthropogenic activities. Indeed, overconfident animals may easily be injured or even destroyed if displaying invasive or aggressive behavior towards humans.

The scientific and conservation objectives of DOR are as follows:

1. Long-term demographic and ecological monitoring of the Tiputa bottlenose dolphin community - abundance, community structure, site fidelity, social organization, reproduction parameters, kinship, diet.

2. Long-term ethological monitoring to describe and better understand the impacts of tourism on the dolphins’ behavior and risks related to close interactions between dolphins and divers.

3. Awareness raising of the general public through the sharing of our results and recommendations. This work aims at improving and perpetuating our relationships with wildlife.

WHAT IS THE ROLE OF THE VOLUNTEER?

Volunteers are trained to identify Rangiroa bottlenose dolphins, basic behaviors and help collecting underwater video data.

Minimum level 1, Open Water PADI / SSI or equivalent is required to participate in scuba diving activities. It is possible to get certified on site after about a week of training. We advise people wishing to get certified to come one week before the beginning of the mission. Do not forget to bring your certification card and logbook as well as a medical certificate. In order to be able to enjoy the lagoon we also advise you to bring your own fins, mask and snorkel.

WHAT ARE THE VOLUNTEER ACTIVITIES AND RESPONSIBILITIES?

Divers and / or snorkellers are invited to participate in the following activities:

1. Video shooting of the bottlenose dolphins’ behaviors in the Tiputa area.

Before each dive a briefing on the area prospected, sea conditions and safety procedures is led by the diving instructor. An informal debriefing led by the scientific coordinator takes place after each dive. The divers follow their guide throughout the dive which generally lasts from 45 to 70'. Time spent at sea is approximately 60-90’ depending on the duration of the dive. The sighting area is located about 5-10’ by boat from the center.

2. Boat survey and snorkelling on the ocean side.

When weather conditions are good, boat and snorkelling surveys are organized on the ocean side. The boat drifts over the main dolphin habitat. You will be responsible for collecting a number of simple data without danger or discomfort for you and the dolphins. This activity usually lasts from 70 to 90’. Beware of possible seasickness.

Underwater cameras are highly recommended. The NGO does not provide fins, masks, snorkels and / or wetsuits. 

3. Land sightings.

Long breaking waves - called ‘mascaret’ - resulting from the meeting of a tidal current coming out of the lagoon with ocean water run through Tiputa pass twice a day. This exceptional setting constitutes a privileged socialization area for the bottlenose dolphins which regularly come to surf and leap into the waves. We can practice photo identification and get a glimpse of the social organization of the dolphin community. This activity lasts about 1:30 and is supervised by DOR's scientific coordinator.

4. Part of the day is dedicated to data processing, comments, debates and training courses.

WITH WHOM WILL THE VOLUNTEERS BE WORKING WITH?

The volunteers will be supervised by DOR's scientific coordinator, the captain and diving instructors.

WHAT DO WE EXPECT FROM THE VOLUNTEERS?

Our mission is a participative tool for the demographic, ecological and ethological monitoring of a small and protected bottlenose dolphin community. It will allow you to observe and better understand these animals' routine and issues related to their conservation while helping DOR to sustain its dolphin monitoring program.

WHAT CAN THE VOLUNTEERS EXPECT FROM US?

DOR's scientific coordinator has been monitoring this dolphin community for more than ten years. She will share part of her experience and knowledge to allow you to observe, meet and better understand this small dolphin community. Volunteers are trained to be able to individually identify resident dolphins and get knowledge about their behavioral repertoire.

DO THE VOLUNTEERS HAVE TO BRING SPECIAL EQUIPMENT?

We strongly recommend volunteers to take their own fins, mask and snorkel as well as a lycra or diving suit. It may also be useful to bring a laptop, hard drive and underwater shooting equipment. For your comfort, we advise you to bring a hat or cap, polarized sunglasses, sunscreen, a seasickness remedy, a raincoat, a mosquito repellent and mosquito net, and a tube of antibiotic ointment.

RECOMMENDATIONS

What's Included

Services by Dolphins of Rangiroa (DOR)

The fees include the round trip between the airport and guesthouse, accommodation in dormitory at the ‘Teina & Marie’ guesthouse, breakfast and dinner, common fund for lunches, dives / snorkelling sessions with ‘Raie Manta Club’, training, presentations and scientific supervision of DOR. They do not include international and domestic flights to Rangiroa as well as extra expenses - e.g. alcoholic drinks, restaurants, etc.

Airport Pickup at Rangiroa Airport

Volunteers are expected at Rangiroa airport by the guesthouse. The round trips of approximately 6 kilometers last 5 minutes. In any case, the first meeting takes place at the guesthouse on the first Monday of the mission at 10:00 a.m.

Accommodation

DOR works with the local ‘Teina & Marie’ guesthouse located next to the lagoon, Tiputa pass, the diving center and ‘la Cité des Dauphins’, a dolphin observatory on shore. Accommodation is in a mixed dormitory with a shared bathroom fitted with a toilet, shower and access to electricity. It is possible to request a room and / or choose another pension, in which case an adjustment of prices and organization may be done with DOR. For your personal comfort, we advise you to bring a mosquito net.

DOR works in collaboration with ‘Raie Manta Club’ - RMC -, a small diving structure located next to the guesthouse. The Tuamotu's first diving ‘club’, RMC benefits from its founder’s experience, Yves Lefèvre, a diver and underwater cameraman who has been living for over thirty years in Rangiroa, and from ‘Maco’, the oldest sailor in the island, who is used to assist us in collecting dolphin data. For people wishing to dive with a more modern center, an adjustment of prices and organization may be done with DOR.

Dorm Room Bungalow
Food & Beverages

Breakfast and dinner are covered by the guesthouse. Local meals are often based on fish but may be adapted for vegetarian diets. Lunches are generally organized collectively from a common fund and can be cooked in the house’s kitchen. Two food stores and three snacks are located a few minutes walk from the pension. Shops are relatively well stocked, but fruits and vegetables are scarce in the atolls. You will often have to wait for the freighter from the Marquesas archipelago to stock up on local fruit. A meal at the snack costs about 1,700 XPF and between 3,000 XPF and 6,000 XPF in a restaurant. Alcoholic drinks are not included in fees.
