Ah! But what about the deep sea? Humans obviously haven't seen every inch of it--not even close. And the deepest spot in the ocean, the Challenger Deep, is much harder to visit than the South Pole. In fact, only one manned expedition has ever touched bottom, making it more like the moon than the pole.
And--like the moon--private individuals and entrepreneurs are itching to go back. Media of late have been abuzz with news of the "race to the deep," most recently covered in The Huffington Post.
I must be wearing my pedantic pants today, because I couldn't help pouncing on a couple of statements in the article. They aren't wrong--they're just not perfectly right.
Quibble the first:
Filmmaker and explorer James Cameron has unveiled plans to visit the deepest place on planet Earth in the coming weeks, aboard a state-of-the-art, deep-diving craft built beneath a veil of secrecy in Australia. . . . The lime-green, cylindrical craft, dubbed the Deepsea Challenger -- a play on the name of the deepest spot in the Mariana Trench, known as Challenger Deep -- is a single-pilot submersible . . .Uhh. Does anyone know what the Challenger Deep was named after? That's right, a honking big sailing ship called HMS Challenger that laid the foundation for modern oceanography. I'm pretty sure the ship--not the geographic location--is the namesake for Cameron's vessel.

Quibble the second:
Over the last several decades, scientists have found some bizarre and massive creatures dwelling in the deep, such as the megamouth shark, a filter feeder that grows up to 18 feet (5 m) long, and two enormous and otherworldly squid species.

This strange creature lives in deep, oxygen-limited areas from around 2,000 to 3,000 feet (600 to 900 m.) depth . . .Now, I realize it doesn't explicitly say "vampire squid were discovered in the last several decades." But it sure implies that. Vampire squid were actually discovered over a hundred years ago--see Richard Ellis' account of the history of our knowledge of the beast.

All quibbles aside, though, I'm stoked that someone's going back down there. And I wouldn't be at all shocked if he does find new species of squid--and other creatures, too.
