The Earth's magnetic field varies on many time scales, waxing and waning in strength, and periodically completely reversing direction. The geologic record of these variations provides important information on the history of our planet. Join Scripps Oceanography geoscientist Jeff Gee for a fascinating glimpse into his fieldwork in paleomagnetism -- from autonomous aircraft measurements over the open ocean to exploration of rock exposures in remote regions of Antarctica.

This was very well done! Appreciate the efforts to trim the questions down to the core and keep the talk under an hour (that was very well spent!)

I read a little about paleomagnetism in an intro to physical geology I just finished and was happy to learn more about it. Thank you for posting this video.
