WE ARE PROUD TO BE AN OFFICIAL PARTNER OF UNDER THE POLE

By supporting the Under the Pole expedition, a pioneer in underwater research, we are actively participating in the emergence of a more sustainable world. Our support contributes to a better understanding of the oceans and promotes the preservation of our planet for future generations.

Corals

Coral reefs have gone through tens of thousands of years of evolution. Today, corals will probably be the first victims of the accelerated pace of environmental change, causing local or regional extinctions. About a quarter of the world's coral reefs have already suffered irreversible damage and two thirds are seriously threatened.

WHY SHOULD YOU PROTECT CORALS?

To live, corals need quality water and phytoplankton. Letting corals die is irreversibly breaking a link in the chain that connects us to marine biodiversity and it is simply condemning human beings. In fact, the oxygen we breathe is made 70% by phytoplankton, which need quality water.
Coral reefs play a vital role in balancing the ecosystems of the oceans and the planet

THE DEEPHOPE PROGRAM

A YEAR AROUND FRENCH POLYNESIA TO BETTER UNDERSTAND THE MESOPHOTIC CORALS (BETWEEN 30 AND 150 METERS DEPTH).

THE REFUGE THEORY

DEEPHOPE is a scientific program that studies the corals of the mesophotic zone in order to verify whether surface corals - currently threatened by global warming and human activities - have found refuge in the mesophotic zone to reproduce there, hence the name of refuge-nursery theory

WHAT IS THE BALANCE SHEET
INTERMEDIATE?

9 FAMILIES AND 27 KINDS OF CORALS IDENTIFIED, INCLUDING 2 NEW KINDS AND 1 NEW SPECIES DETECTED FOR FRENCH POLYNESIA

4 SAMPLES OF CORAL TAKEN, MOST OF WHICH ARE SINGLE SAMPLES, NEVER COLLECTED HEREFORE, FORMING THEREFORE THE MOST IMPORTANT COLLECTION IN THE WORLD

On April 4, 2019, in the Gambier archipelago, divers from Under The Pole reported the deepest mesophotic coral ever collected in the world (-172m): the Leptoseris hawaiiensis.

 

“I have been waiting for such discoveries for 40 years. These results will represent a robust and essential basis for testing hypotheses concerning the capacity of mesophotic coral environments to serve as a refuge. "

Michel Pichon,

Coral reef expert biologist

“These discoveries help support the hypothesis of a refuge for surface corals in the depths of the ocean and hope to restore them. "

Founder and director of Under The Pole expeditions

WHAT'S NEXT ?

The main results of the DEEPHOPE program will be presented at the International Congress on Coral Reefs in July 2020 in Bremen, Germany and will reveal in a new light the diversity and biogeography of the coral fauna of the Central East Pacific.

In August 2019, Under The Pole will take on a new challenge, that of saturation diving in the underwater observatory, the “ Capsule Which will allow the divers of the expedition to stay underwater for several days.

The Under The Pole team will continue its studies on corals and in particular on a key moment in coral life: its sexual reproduction. A few nights a year, the coral releases sexual cells into the water column which will fertilize to give a coral larva. This process is vital for the renewal of coral populations, as it allows the arrival of new individuals on the reef. However today, the exact date and time of this key moment in the life cycle of the coral are known only for a few species in French Polynesia and have never been observed in situ.

“Faced with the ecological emergency, it is essential to make every effort to acquire knowledge that will allow us to better protect the oceans and manage their resources in a sustainable manner. We hope that these results will initiate further research and quickly serve as a lever for the creation of new marine protected areas. "

THE CAPSULE PROGRAM

From September to November 2019, the " Capsule », A light underwater habitat, will become a refuge for divers for studies in total and continuous immersion for several days.

This capsule placed 20 meters deep allows divers to rest and feed while observing the wildlife. This cabin exempts divers from the long ascent to the surface which requires 3 to 6 hours of landings for 20 minutes of observation at 120 meters. A real time saver, thus extending the duration of immersions and searches. The " Capsule »Becomes a 2e base camp allowing divers to refuel. At the front row of a breathtaking spectacle, the divers scrutinize the big blue in silence ...

"If yesterday's challenge was to dive deep into the oceans, today, the issue of human underwater exploration lies elsewhere: it lies in its ability to stay in immersion, with the aim of discovering and understanding of the oceans and the life that unfolds there. "
