IMI30: 2004 Lau Basin Survey
During its first scientific program in 2004, the IMI-30 collected sidescan and bathymetry data for the Lau Basin, but only on the port side of the instrument. Sidescan data agreed well with analogous data collected by the DSL-120A, and showed far more detail than the data produced by the Kilo Moana’s hull-mounted EM120 (below). Problems resulted mainly from the potted transducers that flooded.
