12 St. 59 Min, 20 Nov 1963 Jahr - First Multibeam Sounding
Beschreibung:
The first operational multibeam sounding system is installed on the USNS Compass Island. This system observes a number of soundings to the left and right of a ship’s head as well as vertically. This is important because it is the development of a relatively accurate map of the sea floor as the ship proceeds on a survey line
