sonar - by bouncing sound signals off the bottom of the ocean, they were able to map the depth of the ocean. Deep sea diving would take too long. Satellites were not in orbit until the 1970's and submarines were not necessary since sonar could be done from the surface on a boat.

The first one is the sonar used to map out sensed mountains,the second one is scientists found strange rocks shaped like pillows in the central valley of the mid-ocean ridge and the last one is scientists discovered that the rock that makes up the ocean floor lies in pattern of magnetizied "stripes"

What technology did scientists use in the mid 1900's to map the mid-ocean ridge?
they probably would use a sonar which is a device that bounces sound waves off under water objects and then records the echoes of these sound waves. =]
