A different survey was performed in 2001, combining remote sensing techniques such as side scan sonar and an echo sounder with visual survey by archeologist divers.
In order to meet these standards, the surveyor must consider not only the vertical and horizontal accuracy of the echo sounder and transducer, but the survey system as a whole.
Measurements on the mass balance of the glacier, as well as more detailed ice thickness measurements using a portable radar echo sounder, were undertaken.
