People have travelled to the Mediterranean for thousands of years, and it is believed to have no secrets. And yet, far below its surface, lie vast unexplored territories, luxurious gardens worthy of the finest tropical coral reefs. These natural wonders are inaccessible to the traditional diver, set in a twilight zone between 60 and 120m, where there is less than 1% of sunlight. If diving at such depths is always a challenge, staying there is regarded a fantasy, but this utopia becomes a reality in The Deep Med.

In the tradition of Commander Cousteau and his “houses under the sea”, Laurent Ballesta’s team undertake a new world-record setting mission in July 2019: to spend 28 days in a pressurised 55sqft capsule allowing them to dive into the 100m zone as they wish, in complete freedom and without time constraints.

From Marseille to Nice, the 4 adventurers reveal the remarkable treasures of biodiversity hidden in the Mediterranean and study the unknown ecosystems of its depths.
