Their names are Qumaira, Petra, Dirk, Ulla.... They hit France throughout the autumn and winter. Behind these names hides a succession of violent storms the likes of which France has rarely experienced. The entire coastline still bears traces of it. How do we experience these storms in threatened areas of the seaside? What are the consequences for the erosion of our coasts? And what concrete solutions are there to limit the effects of wave strike? Thalassa tries to answer these questions by going to meet those who, on the coasts of Brittany, Normandy, Aquitaine or the Mediterranean, face the wrath of the sea but who would not leave their corner of the coast for anything in the world.

Scotland sometimes looks like the end of the world, the "Far West" of Europe. To live in this territory is to accept the rules of the game of Nature, on the sea as well as on land. Whether on the remote Hebridean Islands, along the rugged coasts, in lochs lined with clumps of heather or at the foot of a castle hidden in the mist, Scotland is a region full of legends and stories that span the centuries. Nature is strikingly beautiful. The men who have chosen to live here claim their freedom and protect their heritage with pride, from the Scottish Sea to the North Sea.
