Our country has two exploration programs.

One is NASA, with a mission to explore the great beyond,

to explore the heavens, which we all want to go to if we're lucky.

And you can see we have Sputnik, and we have Saturn,

and we have other manifestations of space exploration.

in another agency within our government, in ocean exploration.

It's in NOAA, the National Oceanic and Atmospheric Administration.

And my question is this: "why are we ignoring the oceans?"

Here's the reason, or not the reason, but here's why I ask that question.

If you compare NASA's annual budget to explore the heavens,

that one-year budget would fund NOAA's budget

Why? Why are we looking up? Is it because it's heaven?

And hell is down here? Is it a cultural issue?

Or do they just assume the ocean is just a dark, gloomy place

I'm going to take you on a 16-minute trip on 72 percent of the planet, so buckle up.

is we're going to immerse ourselves in my world.

And what I'm going to try -- I hope I make the following points.

I'm going to make it right now in case I forget.

was not in my textbooks when I went to school.

And most of all, it was not even in my college textbooks.

I'm a geophysicist, and all my Earth science books when I was a student --

I had to give the wrong answer to get an A.

We used to ridicule continental drift. It was something we laughed at.

We learned of Marshall Kay's geosynclinal cycle, which is a bunch of crap.

In today's context, it was a bunch of crap,

but it was the law of geology, vertical tectonics.

All the things we're going to walk through

in our explorations and discoveries of the oceans

were mostly discoveries made by accident.

We were looking for something and found something else.

represents a one tenth of one percent glimpse, because that's all we've seen.

This is a characterization of what it would look like if you could remove the water.

It gives you the false impression it's a map.

In fact, I have another version at my office

and I ask people, "Why are there mountains here, on this area here,

but there are none over here?" And they go, "Well, gee,

"Is it a fracture zone? Is it a hot spot?"

No, no, that's the only place a ship's been.

Most of the southern hemisphere is unexplored.

during Captain Cook's time than now. It's amazing.

All right. So we're going to immerse ourselves

in the 72 percent of the planet because, you know,

it's really naive to think that the Easter Bunny

We are always, constantly playing the zero sum game.

You know, we're going to do this, we're going to take it away from something else.

And we're leaving so much on the table, 72 percent of the planet.

And as I will point out later in the presentation,

50 percent of the United States of America lies beneath the sea.

50 percent of our country that we own, have all legal jurisdiction,

have all rights to do whatever we want, lies beneath the sea

and we have better maps of Mars than that 50 percent.

Why? OK. Now, I began my explorations the hard way.

Back then -- actually my first expedition

was when I was 17 years old. It was 49 years ago.

Do the math, I'm 66. And I went out to sea on a Scripps ship

and we almost got sunk by a giant rogue wave,

and I was too young to be -- you know, I thought it was great!

I was a body surfer and I thought, "Wow, that was an incredible wave!"

And we almost sank the ship, but I became enraptured

with mounting expeditions. And over the last 49 years,

I've done about 120, 121 -- I keep doing them -- expeditions.

But in the early days, the only way I could get to the bottom

was to crawl into a submarine, a very small submarine,

I dove in a whole series of different deep diving submersibles.

and all the major deep submersibles we have, which are about eight.

In fact, on a good day, we might have four or five human beings

maybe four or five human beings out of whatever billions we've got going.

And so it's very difficult to get there, if you do it physically.

But I was enraptured, and in my graduate years

was the dawn of plate tectonics. And we realized

that the greatest mountain range on Earth lies beneath the sea.

The mid-ocean ridge runs around like the seam on a baseball.

But if you were to put it on an equal area projection,

you'd see that the mid-ocean ridge covers 23 percent

Almost a quarter of our planet is a single mountain range

and we didn't enter it until after Neil Armstrong

So we went to the moon, played golf up there,
