From Watts Up With That?<\/a><\/p>\n\n\n\n

By Anthony Watts<\/a><\/p>\n\n\n\n

For 540 million years, the ebb and flow in the strength of Earth\u2019s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released analysis by NASA scientists. The research suggests that processes deep inside the Earth might influence habitability on the planet\u2019s surface.<\/p>\n\n\n\n

Earth\u2019s magnetic field arises from the flow of material in the planet\u2019s molten interior, which acts like a giant electromagnet. The flow isn\u2019t perfectly stable, and this causes the field to change over time. <\/p>\n\n\n\n

Many scientists have argued that the magnetic field is crucial for protecting the atmosphere from eroded by energetic particles coming from the Sun. But, the authors of the study in Science Advances<\/em><\/a> point out, the role of magnetic fields in preserving the atmosphere is an area of active research. Before addressing the complexity of the cause-and-effect relationship between magnetic fields and oxygen levels, the study authors decided to see whether Earth\u2019s magnetic field and atmosphere have fluctuated in ways that demonstrate a link.<\/p>\n\n\n\n

The history of the Earth\u2019s magnetic fields is recorded in magnetized minerals. When hot minerals that rise with magma at gaps between spreading tectonic plates cool down, they can record the surrounding magnetic field.  The minerals retain the field record as long as they are not reheated too severely. Scientists can deduce historic oxygen levels from ancient rocks and minerals because their chemical contents depend on the amount of oxygen available when they were formed. Data for both Earth\u2019s magnetic field and oxygen extend over comparable ranges in databases that myriad geophysicists and geochemists have compiled. Until now, the authors of the new study say, no scientists had made a detailed comparison of the records.<\/p>\n\n\n\n

\u201cThese two datasets are very similar,\u201d said coauthor Weijia Kuang, a geophysicist at NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland. \u201cEarth is the only known planet that supports complex life. The correlations we\u2019ve found could help us to understand how life evolves and how it\u2019s connected to the interior processes of the planet.\u201d<\/p>\n\n\n\n

When Kuang and colleagues analyzed the two separate datasets, they found that the planetary magnetic field has followed similar rising and falling patterns as oxygen in the atmosphere for nearly a half billion years, dating back to the Cambrian explosion, when complex life on Earth emerged. <\/p>\n\n\n\n

\u201cThis correlation raises the possibility that both the magnetic field strength and the atmospheric oxygen level are responding to a single underlying process, such as the movement of Earth\u2019s continents,\u201d said study coauthor Benjamin Mills, a biogeochemist at the University of Leeds.<\/p>\n\n\n\n

The researchers hope to examine longer datasets to see if the correlation extends farther back in time. They also plan to investigate the historic abundance of other chemicals essential for life as we know it, such as nitrogen, to determine whether they also support these patterns. As for the specific causes linking the Earth\u2019s deep interior to life on the surface, Kopparapu said: \u201cThere\u2019s more work to be done to figure that out.\u201d<\/p>\n\n\n\n
