After sounding data is collected in the field, it is processed nightly and over the project period. Data processing involves moving the acquired data to the ship's network, correcting the data for tides and sound velocity, and rejecting errant soundings. The data also goes through a quality control check.

Night processing is the first check of acquired data. This first check may affect the next day's acquisition. For example, if positioning was poor, an area may be re-surveyed. Night processing also determines how much data was collected so the crew can plan for the next day.

Acquired data is given closer scrutiny over the next few days by assigned personnel. This includes analyzing each dataset and looking for features such as wrecks or significant shoals. If necessary, more data will be acquired in the field to verify such features.

The data goes through a final check by assigned personnel. This quality control check is the last step before final analysis and chart comparison. Field plots are developed and an analysis report is written after comparisons are made.
