'Sonar". And determines depth. The ocean floor topography can be mapped by 'sonar scanning'.
It maps ocean-floor features, sea beam relies on sonar which is the use of sound waves to detect & measure objects underwater.
ocean depth
to calculate the depth of the ocean floor
Sound waves bounce off the ocean floor and come back up to whatever emitted it. The time it takes for the sound wave to come back tells how far down it went. Doing this many times over and over, one can map out the ocean floor, and if the sound wave comes back relatively fast, that means there is something on the ocean floor.

Depth is a measure of distance between the surface and the ocean floor.
A thermometer is sufficient.
Sonar.
They pay the divers to go to the end of the ocean and measure the ocean floor depth before divers dive they take a long endless string keep it up the surface then take it al the way down and cut to where it ends so that when they are finished they measure
Lead Weight
They measure how far away the rock is from the mid-ocean ridge. The farther, the older.
The topography of the ocean floor
which landforms are on the ocean floor
The ocean floor is not smooth.The ocean floor is made up of rocks, ledges and ditches.
blank are found on the ocean floor
