Arqueojerks, tormentas geomagnéticas y ionosfera. Hablamos con Saioa Arquero Campuzano.

from Cienciaes.com

La investigadora Saioa Arquero Campuzano explicaba en un programa anterior que la Tierra se comporta como un inmenso imán cuyos polos se mueven con el tiempo. Así aprendimos que el campo magnético terrestre no solamente varía en dirección sino en intensidad y sus variaciones han quedado reflejadas en diminutas partículas imantadas que, a modo de pequeñísimas brújulas, han ido quedando atrapadas en los sedimentos a lo largo de la historia de nuestro planeta. Hoy volvemos a contar con Saioa a raíz de la publicación de dos nuevas investigaciones que aportan información sobre el comportamiento del campo magnético terrestre. La primera estudia ciertas variaciones del campo magnético que han tenido lugar durante los últimos 3.500 años de historia. Esas variaciones, lejos de ser suaves, presentan impulsos tanto en dirección como intensidad, conocidos como arqueojerks. El segundo trabajo analiza los efectos de una tormenta geomagnética de intensidad moderada que alcanzó la Península Ibérica y el norte de África el 26 y 27 de febrero de 2014.
