Acoustically Navigated Geological Underwater Survey
The Acoustically Navigated Geological Underwater Survey (ANGUS) was a deep-towed still-camera
ANGUS has been used to search for and photograph underground
used on both dives to the Titanic.On Project FAMOUS, ANGUS helped change scientists' views of the ocean floor. It showed them how different geological formations and chemical compositions of sediments can be, disproving previous assumptions of ocean floor uniformity [5] The project also provided new insight to the theory of seafloor spreading by observing and sampling the rock formations around ridges and the horizontal formation of layers parallel to the ridge.[5]
In another 1977 expedition with ANGUS, scientists monitored temperatures over the ocean floor for any fluctuation. It was not until late at night the crew noticed temperatures rise drastically. They would review the photograph footage taken after the vehicle's session. to take samples.
Scientists nicknamed ANGUS Dope on a rope [2] due to its durability and lack of fragile sensors. It was also given the motto "takes a lickin' but it keeps on clickin'". ANGUS was retired in the late 1980s, having completed over 250 voyages.[1]
