NOAAS Mount Mitchell (S 222) was an American survey vessel in commission in the National Oceanic and Atmospheric Administration from 1970 to 1995.

Prior to her NOAA career, she was in commission in the United States Coast and Geodetic Survey as USC&GS Mount Mitchell (MSS 22) from 1968 to 1970.

Launched on 29 November 1966, she was commissioned into the Coast and Geodetic Survey in March 1968 as USC&GS Mount Mitchell (MSS 22).

Mount Mitchell conducted hydrographic surveys on the United States East Coast and in the Caribbean, and served as an oceanographic vessel throughout much of the North Atlantic Ocean on various projects.

Mitchell, Atlantic Marine Center, completed a historic cruise surveying environmental damage in the Persian Gulf caused by oil spills.

The cruise is the first major oceanographic survey of the Persian Gulf since 1977 and is the most comprehensive ever in terms of geographic and subject area coverage.

With her refit complete, she arrived in Seattle, Washington, in 2003 to begin her career as the private research ship R/V Mt.

The vessel is an acoustically quiet platform capable of supporting sophisticated sonar operations in deep water and high sea states.

Mitchell was outfitted with stabilization tanks and anti-roll chocks which have eliminated much of her natural roll, making her an ideal platform for surveying.
