The First Map of the Depths


This map marks both a scientific and an imaginative revolution.
When it was published in 1977 by Marie Tharp and Bruce Heezen, two oceanographers at Columbia University, there had never before been a map of the entire ocean floor. Here, for the first time, was our planet's hidden majority. It was as if the plug had been pulled and the water drained out, transforming the blank seascape into a complex landscape of plains and peaks, escarpments and bluffs. Here was the full extent of the Mid-Ocean Ridge, the mightiest mountain range on Earth, its 40,000-mile length making molehills out of more familiar mountains. You can see its serpentine curl through the Atlantic, round the Cape of Good Hope to the Horn of Africa and on through the Southern Ocean, up to 1,000 miles wide and two miles high.

Your Say

Imagine if, like the poles switching end for end, the water changed places with the dirt, instantly.

Maybe it'd make a better movie if the change happened over, say, 24 hours.

Or if gravity lessened by 50%. That'd be cool. 2 hops and a skip and you're on the left coast. Reverse it and you're eating Maine lobsters....

If they could go back and redo a lot of areas that seem to be smuged like around the 'Isla Cedros' off Baja Ca. among other areas. It would be nice to see the Ocean bottom around there. Seems to be a rather large area affected.

@ghost: I don't think they can do that. The planet would have to be twice as large to fit all that water in. And all them countries wouldn't float, would they? Best thing to do is, take a bunch of that sea water and send it into outer space. Either that or make drinking water out of it. That would make more room for the dirt. I thought about leveling all the mountains off, pushing the rocks and dirt and stuff into the oceans but I can see now that would never work. Maybe fill in a bunch of lakes or something but not the oceans.

My uncle Louis Lozko, we all called him "Letsgo Lozko", he raised bantam chickens. One time he decided to move the chicken coop over to the back end of his property. It was a mess. He jacked it up like they do houses and put it on a low trailer but he couldn't fit the whole thing and part of it dragged and came apart before he got it situated. On top of that, where he used the truck to pull the trailer, he couldn't turn the truck around after he dropped the coop and he knocked down part of the neighbor's fence and besides that, he lost some of his flock when the coop came apart. He wouldn't talk to anybody for the rest of the day, especially his wife with her "I told you so's"
