Ghislain Bardout and Emmanuelle Périé-Bardout, will be working in cooperation with teams of scientists on the sailing boat WHY for a land-based and underwater expedition in the polar environment.
Objective: To study the arctic ecosystem over its entire annual cycle, both on the surface and under the ice bank
How? The Under Pole II team will sail along the continental plate of western Greenland, monitoring the melting of the ice shelf before spending the winter in the north of the island, near Uummannaq.
scientists and divers involved
including 40 at a depth of around 100 m
1. Interactions between the ice bank, the atmosphere, and the ocean in an endangered ecosystem
UTP II will measure the quantities of carbon dioxide captured in the depths of the ocean. Indeed, polar ice traps CO2 and oxygen when it is formed. This gas accumulates in extremely salty pockets of water called "brine". Due to their higher density, these pockets sink to the depths of the ocean, taking the captured gas with them.
2. Human physiology during dives in extremely deep and extremely cold water
Several physiological measurements of divers will then be analyzed in order to monitor the tolerance of the human body to extreme environments and optimize recommendations for divers.
The Air Liquide Foundation's €120,000 subsidy over two years is dedicated to buying equipment required for the expedition. The Foundation has also provided the diving gas and the oxygen therapy kits for UTP II: around 60 oxygen and helium bottles were delivered to the boat before it left Brittany and along the coast of Greenland, thanks to the support of Air Liquide's subsidiaries in France and Greenland (Air Liquide Denmark).
The Air Liquide Foundation supported the first «Deepsea Under The Pole » in 2010.
