Explorer and film-maker James Cameron just completed the first-ever solo dive to the deepest point in the ocean in the Mariana Trench.
I can imagine a bit of what this felt like, I once was privileged to dive 10,000 feet to a hydrothermal vent site off the Galapagos Islands. The Mariana Trench, hallowed water for oceanographers, is about 35,800 feet. I expect the National Geographic writeup will include an exact measurement using modern technology and stunning visuals. Stay tuned.
For now, cheers for a grand adventure and adventurer, proving that the age of heroic exploration is not over.
