While there are public domain relief map datums including bathymetry available, for some reason, the ones I have found have tended not to be as... dramatic as the famous ocean floor map that Marie Tharp was instrumental in creating.
I looked around to see if I could find other maps based on that map.
I learned that National Geographic actually went to Heezen and Tharp for the artwork they used rather than creating their own for their maps!
I found one independent redrawing that was done by one Tanguy Remur; this one is copyright by a French publisher.
Also, I saw what turned out to be an Alamy stock photo showing part of what appears to be a map in the Wagner VII projection.
I was thinking that there ought to have been a map based on the Tharp data, with dramatic ocean floor relief, but published by the U.S. Navy for its own use, and hence in the public domain as a U.S. Government work, but my Google-fu has not yet been sufficient to turn it up.

Re: Maps Based on Heezen-Tharp
Oh, I’d LOVE to have a map like that!
I remember seeing the Heezen-Tharp (at least, the Atlantic ocean floor part) in a schoolbook – and I think I didn’t listen to what the teacher said in that lessen because I was staring at the map all the time.
A few years ago, I tried to generate a map like this based on ETOPO data but I didn’t even come close.

Re: Maps Based on Heezen-Tharp
Yes, I remember that the last time I was dealing with this question, I found I needed a working Linux machine handy to run the program that would take an image file where grayscale indicated elevation, and convert it to a shaded relief; that was one other thing I considered trying.
It seemed logical, though, that there would be an independent redrawing of that map by the U.S. Naval Hydrographic Office that would be in the public domain, which has led me to search around, but so far no luck. I did find some weird things, though. Someone made a map, which is being sold as a wall decoration, based on an ocean map from Bartholemew's Times Survey Atlas of 1922, but with Heezen Tharp as an underlay!
