A Dipole Field from the Ediacaran-Cambrian Transition Onward?

by Mark J. Dekkers 14 October 202114 March 2023

The Ediacaran features an instable magnetic field complicating paleogeographic reconstructions; a new paleointensity study on late Ediacaran rocks indicates a weak but stable dipolar field.

Scientists Mine 16th Century Ship Logs for Geophysical Research

Jenessa Duncombe, Staff Writer by Jenessa Duncombe 17 May 20215 March 2026

Compass measurements held a key to unlocking the mystery of Earth’s magnetic field and its changes over time. A historian-turned-geoscientist found the measurements in an unlikely place—merchant ship logs.
