If "under the ocean" or "under the sea" means underwater, under the surface. Then what should we say to point to something under the "under the ocean, sea"?

I was thinking of:

  • Under the ocean floor.
  • Under the sea floor.

Also, is undersea or underocean possible based on that underground is.

You could say several things:

  • Under the ocean floor
  • Under the sea floor (or seafloor)
  • Beneath the bottom of the ocean

There are technical terms like "lithosphere", but that's probably not what you want. You could also refer to the Earth's crust directly.

"Undersea" is a word. I've never heard anyone say "underocean",

    Also, beneath the ocean floor.
