Goss and her editors looked into the impact the Earth’s magnetic field has on all of us for our January issue of Eos. A big reason we thought the topic was worth an entire issue is, as Bowles said, “there is a lot of interesting crossover between the magnetism community and many other Earth science communities.”
Indeed, this topic was originally suggested by Carol Stein, at the Department of Earth and Environmental Sciences at the University of Illinois at Chicago, Eos’s science adviser for AGU’s Tectonophysics section, who noted the importance of understanding magnetism for so many scientists throughout AGU’s sections.
Finally, they couldn’t cover studies of the magnetic field without recognizing how truly strange it is. In “The Herky-Jerky Weirdness of Earth’s Magnetic Field” , they took a look at the big dent known as the South Atlantic Anomaly, the origin of so-called geomagnetic jerks, and other oddities, “some of which have important societal implications,” according to Bowles. They indicated that our understanding of geomagnetism is now a lot better than “a best guess.”
