By "seeing" under water.
Sonar.
Scientists use echo sounders or sonar technology to measure ocean depth. These tools work by sending sound waves down into the water and measuring how long it takes for the sound to bounce back, allowing scientists to calculate the depth of the ocean floor.
Scientists used sonar technology to discover underwater mountain ranges. Sonar works by sending sound waves that bounce off objects in the water, allowing researchers to create detailed maps of the ocean floor.
Two topographic features of the ocean floor discovered with sonar are underwater mountain ranges known as mid-ocean ridges and deep ocean trenches. Sonar technology allowed scientists to map these submarine structures and gain insights into plate tectonics and the Earth's geology.
Prior to the 1950s, scientists had limited access to advanced technology that enabled deep-sea exploration. Sonar technology and submersibles were not widely available, making it difficult to study the ocean floor in detail. Additionally, the vast size and depth of the ocean made it a challenging environment to explore and understand.
Sonar provides detailed images of small areas of the ocean floor.

One technology oceanographers use to explore the ocean floor is multibeam sonar. This advanced sonar system emits multiple sonar beams in a fan shape to create a detailed 3D map of the seafloor topography. Multibeam sonar helps scientists to accurately study the features and structures of the ocean floor.

The 1925 Meteor Sonar was invented by Albert Beaumont Wood, a British engineer and inventor. His work with sonar technology significantly contributed to advancements in underwater acoustics during that time.
They used sonar So dont be an idiot correct the mistake and ask another question
I believe that Lewis Nixon was 45 when he invented sonar. He was born in 1861. Kelly Nixon Mayr
