Mt. Mitchell

MT. MITCHELL

231 Ft Hydrographic Research Ship
The R/V Mt. Mitchell is a USCG inspected hydrographic research vessel managed by Global Seas. First commissioned as a survey ship for NOAA in 1967, the vessel was purchased in 2001 by Mt. Mitchell LLC and completely refurbished with the latest in electronics, machinery, and safety equipment. The vessel arrived in Seattle in 2003 to begin her career as the only privately owned west coast research vessel with the ability to map the ocean down to 11,000 meters. The Mt. Mitchell is an ideal vessel for most types of oceanographic research operations including, but not limited to: oceanographic mapping, sub bottom surveys, geophysical research, cable route surveys, shallow and deep water AUV operations, and pipeline surveys.

State-of-the-Art Full Ocean Mapping Capability
The Mt. Mitchell is outfitted with today’s most advanced underwater mapping equipment and maps at speed between 7 and 8 knots.  To ensure clean data and reliable performance, the transducers are installed in a gondola to keep them in clean water flow and free from turbulence in all workable sea state conditions. The vessel is also equipped with stabilization tanks and anti-roll chocks to eliminate much of the vessel’s natural roll making it an ideal platform for surveying.
