Mapping the Sea—Soundings to Satellites
Lecture no. 4 from the course: Oceanography: Exploring Earth's Final Wilderness
Taught by Professor Harold J. Tobin | 33 min | Categories: The Great Courses Plus Online Science Course
The ocean floor was once as mysterious as the surface of another planet. Investigate the technologies involved in measuring bathymetry, the undersea counterpart of topography. Weighted ropes and cables for gauging the depth of the sea have given way to sophisticated sonar from ships and radar from satellites.
