August 2013. Underwater photography in Gironde Estuary, Charente-Maritime, France

We started again to dive in the mouth of the Gironde estuary. It's cold, very dark. The currents are strong. But the estuary is magical with its biodiversity, its colors. Conditions are totally unpredictable. We must dive in and cross your fingers. But it is beautiful and astonishing. These photographs are for a new project that will end in 2014.
