Full Version: shaded relief of the Earth's oceans

Hello,

I'm looking for a shaded relief map of the floor of the Earth's oceans. Someone gave me a link to an NOASS site but none of the mpas they had were true-color, they were all topographical. Any ideas?

Thanks

The National Geographic Society? I'm sure that I've seen such a map included with the monthly magazine.

How would you know what true colour was?

Incidentally, I didn't type it like that! I typed "NOAA." I must have accidentally typed an "s."

Meaning, not with different colors representing different depths.

I assume the oceanbottom surface isn't red or purple.

I'd have to get a subscription then, right? I'm right now just looking for the map.

Have you looked at the ocean floor map used in Google Earth?

A couple of places with images where you might look...

I have. I'm more interested in maps that have already been printed, to hang on a wall.

This is exactly what I want! Except that it doesn't have an "add to cart" button!

Something like these?
Ocean Floor Poster 1 2

There's also a really great poster that you can download and get printed here.

A straightforward Google search came up with all of these. Give it a try! smile.gif

It's the whole "get printed" bit. The print shops to which I've gone with these sorts of things suggest it would be prohibitively expensive. I could print on my printer except there would inevitably be a margin on each page and I'd need a lot of 8 1/2 X 11's to print something, and it wouldn't look so hot, either.

Though I do thank you for the links! I have done searches with Google and had no luck finding exactly what I wanted.

There are lots of online printers these days that are reasonably priced - I just put the 1.3m x 1.0m size quoted for that map into a poster printing site I've used in the UK before and get a quote of £39 (~$55 US) Not too bad for such a large photo quality print.

National Geographic sells maps separately.

1981 World Ocean Floor Map
This beautiful physical world map, first published in December 1981, captures the oceans and land of the Earth as only National Geographic can. Stunning relief shading accentuates the drama of the Earths underwater world. See the ocean floor, mountain ranges, river valleys, deserts, and continental shelves, in amazing detail and beauty.

As a matter of fact much of the deep ocean floor is red.

Hi - you can purchase this type of poster from the NGDC for $18. I have an older version of it. Still has colors though:

As for other online images, here are a few links related to the ETOPO2 datasets from the NGDC and SOS websites:

To revive a long-dead thread with a bit of news, there is a project to map the ocean floors, and I mention this here mainly because it offers a case for comparison with the mapping of other bodies.

https://seabed2030.org/faq

The goals are, in comparison with our maps of other worlds, shockingly modest – to map the depth of most of the ocean floors at a resolution of only 400 meters per element. Thus far, the project is about 21% complete, but the organizers express hope that it will nonetheless be complete by 2030 (hence the name).

This may be interesting to compare with the mapping of, say, Venus by Magellan.

Of course, unlike the surfaces of other worlds, we have the opportunity to perform in situ exploration of the oceans at specific points on an extremely widespread basis.
