The 20 development in oceanographic research development in oceanographic research: modern technological development was used. I nstruments and sensors (electronic instead of mechanical) Military""s role in the development of oceanography. s role in the development of oceanography: government involvement in oceanography. Government involvement in oceanography: i nternational cooperation was needed. 1-dimensional case x x2 t2 x1 t1 speed distance time x. 2 distance speed time time distance speed. Modern technological development (right) echo sounders sense the contour of the seafloor by beaming sound waves to the bottom and measuring the time required for the sound waves to bounce back to the ship. If the round-trip travel time and wave velocity are known, distance to the bottom can be calculated.
