Local magnetic disturbances of up to 37° from normal variation have been observed in which harbor's approaches?

• A. Oshawa
• B. Trenton
• C. Hamilton
• D. Kingston

Answer: (D)

Kingston is known for its local magnetic disturbances, which can deviate significantly from the expected normal variation. These disturbances, observed to be as much as 37°, are primarily due to geographical and geological factors in the area that affect magnetic fields. These anomalies may come from the presence of iron-rich deposits in the region or other environmental factors affecting magnetic compasses used by navigators. In the context of the other harbors mentioned, they do not report disturbances of such magnitude. Each harbor may have its own local navigational challenges, but Kingston stands out because the significant degree of magnetic variation poses potential risks for navigation and requires careful consideration by mariners. Understanding this phenomenon is essential for safe navigation in Kingston's waters, making it crucial for local knowledge in maritime operations.
