The term 'Blue Nose' indicates that a sailor has successfully crossed the Arctic or Antarctic Circle. This distinction is often awarded after enduring the specific challenges that come with sailing in extreme cold climates. The phrase likely originates from naval traditions and ceremonies associated with such crossings, where sailors would partake in specific rituals to commemorate their achievement, often resulting in being dubbed a "Blue Nose." Those who have earned this title are recognized for their experience and capability to operate in harsh maritime environments.

In contrast to this, the other options refer to different qualifications or experiences within naval service. Specialists in naval engineering, individuals who have cross-trained in multiple divisions, or those who have served multiple tours overseas do not earn the 'Blue Nose' designation, which specifically ties to the geographical milestone of crossing the polar regions. This makes the understanding of the term 'Blue Nose' unique and deeply connected to the sailor's experiences in the Arctic or Antarctic.
