Shipboard Operations

Onboard Computing Operations

The onboard computing system integrates GPS navigation data with digital pitch and roll data for fundamental navigation. A computer is dedicated to each scientific sensor mounted on the vessel. At the beginning of each survey, instrument calibrations are conducted and adjustments are made to optimize signal reception and data quality. Operators for each data-source monitor incoming data and provide critical information to scientists and other technicians onboard. The computing system and operators perform real-time evaluation of data acquisition, data processing and data archiving.

Typical mapping operations are conducted along parallel lines, similar to lawn mowing. The lines are called track lines and are planned prior to the cruise. The track lines traversed by the vessel are usually within 1-2 meters of the planned route. Actual vessel track lines are recorded during the survey with the navigation equipment.
