In Uummanaq Bay in Greenland, two after their wintering, Ghislain Bardout, Emmanuelle Périé-Bardout and the rest of the team meet their friends Jorgen and Johanna. The emotion is intense and the happiness to be back after these years is not feigned... Then it is time to reach Ikerasak, where divers prepare the underwater equipment for the natural fluorescence program.
While in hot water, traces of fluorescence are found, it is a little blurred in Antarctica. Nobody's ever looked before. The idea is to see if there are fluorescent animals and to understand why they are and what they do with them: behaviour, camouflage, communication..
To be sure not to miss anything, Ghislain takes with him a camera specially mounted to film or photograph biofluorescence. Now it is time to sample the seabed, equipped with ultraviolet lamps
Then we find the couple in front of the computer, downloading the latest weather maps and ice cream. The objective? Verify that all conditions are met to cross the Northwest Passage. And the news is good since all the lights are green and the region is clearing..
