the earth's least-visited floor, mapped worse than the surface of Mars.
means The seabed is the solid ground at the bottom of a sea or ocean, lying beneath all that water.
from A plain English compound of "sea" and "bed," both ancient Germanic words. "Sea" traces back to Old English sǣ and a Proto-Germanic root shared with German See and Dutch zee; "bed" comes from Old English bedd, the same word for a sleeping-place and, by easy extension, any flat resting surface — think of a riverbed or a flowerbed. So the ocean, like a sleeper, has its bed; the floor it lies upon.
