At SHA 2016, evidence was presented, and subsequently published, demonstrating that strong magnetic field perturbations resulting from Earth-directed solar events can adversely affect marine archaeological survey. Survey and observatory magnetometer data from mid-latitude regions confirmed the immediate onset of geomagnetic storms and the fast compression of the magnetopause, creating a short-duration, high amplitude spike in Earth’s magnetic field that appears similar to the signature of an...
Recognizing Geomagnetic Storms in Marine Magnetometer Data: Toward Improved Archaeological Resource Identification Practices (2016)
Strong magnetic field perturbations resulting from Earth-directed solar events can adversely affect marine archaeological survey. The immediate onset of geomagnetic storms and fast compression of the magnetopause create short duration, high amplitude spikes in Earth’s magnetic field that appear similar to signatures of archaeological anomalies. Aggressive processing, analysis, and comparison of single instrument survey and observatory datasets collected during geomagnetic storms prevented...
