| 21. | His work on tectonic paleomagnetism in Italy led to a study of the geomagnetic reversals recorded in Italian deep-sea limestones.
|
| 22. | Is antimatter made by reversing the polarity of subatomic particles ? and I slightly understand the geomagnetic reversal for the earth.
|
| 23. | During a geomagnetic reversal or a global polarity excursion 14C production increases during the period when the geomagnetic field is weaker.
|
| 24. | :: : : There are two kinds of geophysical event which can affect 14C production : geomagnetic reversals and polarity excursions.
|
| 25. | During either a geomagnetic reversal or a global polarity excursion, 14C production increases during the period when the geomagnetic field is weak.
|
| 26. | It is fairly certain, though, that in the last 50, 000 years there have been no geomagnetic reversals or global polarity excursions.
|
| 27. | :: There are two kinds of geophysical events which could have affected production in the past : geomagnetic reversals and polarity excursions.
|
| 28. | It was during his time at the observatory that he made the crucial observation that led to his discovery of geomagnetic reversal.
|
| 29. | In the 1960s, the past record of geomagnetic reversals was noticed by observing the magnetic stripe " anomalies " on the ocean floor.
|
| 30. | Maybe the loss occurs slowly enough that the temporary loss of magnetic field during a geomagnetic reversal only cause a little atmospheric loss.
