Answer to Question 1

The USS Stewart was the first vessel to make a continuous profile of the ocean. They had an updated
version of the Iceberg Detector and Echo Depth Sounder, a device invented after the sinking of the
Titanic. Information can be found in the section Ocean Floor Is Mapped by Bathymetry.
