What if the water disappeared?

Drain the Oceans
The above link attempts to answer what would happen if the water in all the oceans ran out through a hole in the bottom.

Drain the Oceans: Part II
This link attempts to answer what it would look like on Mars if the water ended up there.

The maps are pretty cool.

Thank you for the link to the part about Mars. Useful, and also funny (the labels on the maps).

And okay, the maps for Earth with less ocean are useful, too: I do need to know what the coastline would be like if the Ice came back and took up a lot of ocean into new glaciers. But those maps don't have the funny labels.
