[If the salt in the sea could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet thick, about the height of a 40 story office building.](http://www.palomar.edu/oceanography/salty_ocean.htm) Man has landed on the moon six times and spent almost 300 hours on the moons surface (not all EVA). Yet man has visited the deepest part of the worlds oceans, Challenger Deep in the Mariana’s Trench, just once. In 1960. For 20 minutes.[Man has visited the deepest part of the worlds oceans, Challenger Deep in the Mariana’s Trench, just once. In 1960. For 20 minutes.](http://en.wikipedia.org/wiki/USS_Trieste) ---

Yeah, but what I wanna know is, when did man visit the deepest part of the world’s oceans, and for how long? And, most importantly, how many times? ---

This is all very fascinating, Genghis, but _I_ would really prefer to know when man visited the deepest part of the ocean. When? How many times? My mind hungers to know. ---

Look, he’s answered your stupid moon question. What I came to this thread looking for was an answer to the following questions: 1. Has man visited the deepest parts of the ocean? 2. How many times (list dates please)? 3. For how long? Thanks for your help in this matter. ---

Mariana’s trench sounds like a nice place to visit and 20 minutes sounds about right. I doubt my wife would let me, though. ---

Screw the trench… it’s the amount of salt in the sea that has me puzzled. If you were to remove it all and coat the earth with it I wonder just how thick of a layer that would form? Hmmm… beats the shit outta me. ---

Visit the Marianas Trench, for 20 minutes, or until topping has melted and turned golden brown. ---

Let’s compare apples to apples here. 300 hours on the moons **sruface** compared to how many hours on the earth’s **surface**? And how long have we spent at the bottom of the MOON’s deepest ocean? I bet it’s less than 20. ---
