Variation in total magnetic field measurements recorded by archival tag DS-3 during a period of solar storm activity (magnitude 1000 nT) in Glacier Bay National Park, Alaska, USA. a Detailed (4-min resolution) total magnetic field measurements (black line) from tags compared to 1-min resolution total magnetic field data from the Sitka Magnetic Observatory (pink line; offset by − 600 nT to allow visual comparison). b Detailed total magnetic field measurements (black line) from tags compared to depth (blue line) reflect a distinct tidal pattern in magnetic field data. c Detailed total magnetic field measurements (black line) compared to tag orientation (tri-axial acceleration) over the time period, where orientation along the X-axis is shown in red, Y-axis in blue, and Z (vertical) axis in green
