The Mariana trench is the deepest known part of the ocean at over 11,000 metres. The graphic below shows just how scarily deep that is! Amazingly, a manned descent was actually achieved in 1960, using the steampunk-sounding Bathyscaphe Trieste

I love visualisations like this.
wow, I used to live in Guam which is not far from this. Impressive!
Everest is 29 thousand feet, or 8.8km, so this trench is quite a bit deeper than the highest mountain. Could we see a contour map showing the shape of the ocean floor and adjacent land?
Wow! It seems we know more about Mars than we actually know about our own oceans. The only 10% being mapped really surprises me. I agree with John Bates – the visualization is great, and put things in perspective. PS. The Piggynap banner is one of the best I’ve seen around on the WEB
Can we have the same scale for the center of the earth?
Can you even imagine how much we don’t know at all? Really life is to big for us to see what at the top or better yet the bottom…..
That is absolutely fantastic, I cant image being that deep.
just imagine what exists down there, both frightening and exciting at the same time
If you look real close at the bottom you can see a bunch of lawyers feeding!

Although a blue whale feeds at a depth of less than 330 feet, it can dive up to 1640 feet. One dive lasts for 10 to 20 minutes.
Not deep enough to keep people from spoiling it, alas.
Far to deep for people to spoil it, no manmade structure that we have at the moment will be able to stay down there for more than a few weeks before being completely crushed.
