A Robust Proxy for Geomagnetic Reversal Rates in Deep Time

North is north, until it isn’t. Earth’s magnetic field has repeatedly reversed itself, with magnetic north sometimes residing closer to today’s South Pole and vice versa. The time between these global-scale swaps has ranged from tens of thousands to millions of years, and the frequency of reversals may be linked to processes in […]

Geomagnetic Storms Probably Don’t Cause Mass Cetacean Strandings

Some coastal regions experience repeated episodes in which cetaceans such as whales and dolphins strand themselves on beaches and shorelines, sometimes by the hundreds. A variety of causes have been suggested for these events, which remain a mystery in marine biology, from the use of active sonar by the military to interactions with […]
