Cruise Report: R/V Surf Surveyor Cruise S1-00-CL, Mapping the Bathymetry of Crater Lake, Oregon, 2000
Mounting Alignment Values
The accurate reduction of swath bathymetric data critically depends on a proper knowledge of the geometry and relative positions of the sonar transducer to the motion sensor, the ship, and the positioning-system antennae (Fig. 7). C&C Technologies, using standard surveying techniques, measured these values before the survey began. All values are measured relative to the transducer.
