Passing the Magnetic North

The Healy passed the magnetic north a few days back.    According to one of the captains aboard, the magnetic north pole is at 82°18 N Longitude and 113° 24 W Latitude. A gyroscope is used on the Healy to determine direction instead of a magnetic compass so there are no navigation issues with passing the magnetic north.  However, it could be a problem for sailors and boaters in smaller vessels using magnetic compasses.   The movement of the magnetic north pole is a natural process.
