Which of the following factors is not typically included in compensation for a multibeam sonar survey?

In the context of multibeam sonar surveys, pitch refers to the up-and-down orientation of the sonar transducer, which can affect the angle at which sound waves are emitted and received. Pitch is considered during data processing to maintain the accuracy of depth measurements, but it is not typically compensated directly in the same manner as heading, heave, and sound velocity.

Heading provides information about the vessel's orientation and is critical for correcting the sonar data to ensure it accurately represents the seafloor. Heave accounts for vertical vessel movement due to waves, which is essential for depth accuracy. Sound velocity in the water column is also vital as it can vary with depth, temperature, and salinity, affecting the speed at which sound travels through the water.

In practice, the compensation for a multibeam sonar survey primarily focuses on the factors that have the most significant direct impact on the accuracy of depth measurements. While pitch is important for correcting data, it is not typically compensated in the same standard manner as the other factors listed.
