There are very few maps of the ocean floor, because it has yet to be surveyed.

Maps (charts) exist based on old lead line soundings and single channel echo
soundings, and now satellite altimeter and gravity data (NOAA-Geos series).
All of which are very poor renditions of the actual seafloor,

Pity you top posted and I can't be arsed to edit it properly -but then,
who cares?

Concerning your claim that the sea floor is mapped using plonkers, that
is a bit rich.

Echo soundings do you mean?

Either way there is a lot to do and improvements will not be made until
someone makes a start. Is it asking too much perhaps that someone with
a little skill at a paint shop programme might interfere with the
earth's axis?

Would the whole world stop turning if someone tried it?

Maybe. People believe incredible things. Mind you; one could look to
the top of the tree at the White House for proof of evolution....
