Want this question answered?
I think that Henry Hess invented echo-sounding devices for mapping the ocean floor. But I am not 100% sure that is the correct answer. LOL <3
no
the ocean floor
Mapping the Ocean Floor with Echo Sounding is the key method scientists use to map the seafloor today
Sonar mapping is needed for ocean research patterns.
SONAR, which was developed by the military to detect submarines.
because the coldness,water pressure and deepnessof the ocean floor the info wasnt accurate because its hard to observe under those conditions
like mountain
the echolaocation for measurnig the bottom of the ocean is the Doppler effect
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.
