I visited the research vessel Knorr during a woods Hole port call in May 1997, twenty-three years almost to the day since Paul Johnson (now at the University of Washington) and I had first gone aboard the ship to install paleomagnetics equipment that Dalhousie University had committed to Project FAMOUS (French-American Mid-Ocean Undersea Study).
In the Paleomagnetics Laboratory, a state-of-the-art magnetometer reads the record of Earth's magnetic field changes, information that helps determine the ages of rocks cored and at what latitude they were originally formed.
