For the past year, researchers at the Seaquarium du Grau-du-Roi have been organizing night dives off the coast of coastal resorts. The goal is to identify species on the seabed and observe their evolution with climate change.
Supervised by the Seaquarium du Grau-du-Roi (Gard), volunteer divers are preparing to explore the marine fauna and flora.I love night diving, because there’s activity that you’ll never see in daylight. All the crustaceans come out.”rejoices Céline, a diver. Equipped with a camera, the divers film each species encountered.
The images allow the Seaquarium to enrich its atlas on marine biodiversity, a means of observing the evolution of the aquatic world, according to global warming. “We risk seeing developments in the future: the disappearance of one species, the entry of another“, specifies Jean-Marc Groul, the director of the Seaquarium.
During their exploration, the divers also recorded the water temperature. That evening, it was 24°C at the surface and 20°C at depth, 2°C higher than normal for the period.
