R/V Knorr Navigation Equipment

Knorr is outfitted with a full suite of navigational equipment as required by regulation and as dictated by her principal scientific missions. The equipment is oriented toward use by the officer on the bridge. Navigation information is available to the scientific party through navigation log books after the cruise and upon request during the cruise. The underway data logging system collects, logs and displays all navigation data for scientific users. Navigation data is also available as a NMEA serial data stream in all the laboratory spaces. In general, the Chief Scientist can specify to the Master the type of navigation data, the frequency of observation, and the method of reporting required by the scientific program. Time-consuming or conflicting navigation activities such as radar watches may require that a member of the science party perform the task using the ship’s equipment.
