The Cosquer Cave is located in the Calanque de Morgiou in Marseille, France, near Cap Morgiou. The entrance to the cave is located 37 m (121 ft) underwater, due to the Holocene sea level rise. The cave contains various prehistoric rock art engravings. Its submarine entrance was discovered in 1985 by Henri Cosquer, a professional diver. The underwater passage leading to the cave was progressively explored until 1990 by cave divers without the divers being aware of the archaeological character of the cave. It is only in the last period (1990–1991) of the progressive underwater explorations that the cave divers emerged in the non-submerged part of the cave. The prehistoric paintings were not immediately discovered by the divers to first emerge from the other side of the sump. The cave was named after Henri Cosquer, when its existence was made public in 1991, after three divers became lost in the cave and died.[1 The cave can now be accessed by divers through a 175 m (574 ft) long tunnel; the entrance is located 37 m (121 ft) below sea level, which has risen since the cave was inhabited. During the glacial periods of the Pleistocene, the shore of the Mediterranean was several kilometers to the south and the sea level up to 100 m (330 ft) below the entrance of the cave.[2][3] https://en.wikipedia.org/wiki/Cosquer_Cave

Scuba diving with compressed air limits you to around 40m depth.

Geologists will say the earth has always cycled between Icehouse and Greenhouse.

Bvr cycles between nonsense and fantasy while lusting for blood.

The 40m limit is for Nitrox - added oxygen. Going deeper tends to bring about the convulsions.
You can dive deeper on just air, just means you're pretty narked doing it.
