SWARM Tracks the Ocean’s Magnetic Field
Earth’s magnetic fields protect us from deadly radiation from high-energy solar particles and cosmic rays. Most of this protective shield is produced by a vast amount of hot molten iron swirling around in our planet’s outer core. But there’s another little-known contributor to our geomagnetic field. It’s the salty and electrically conductive ocean. When salty ocean […]
Earth’s Magnetic Fields Guide Salmon Home to Spawn
Earth’s magnetic fields play a significant role in helping salmon find their way home to spawn, according to two new studies from Oregon State University. After poring over 56 years of data, the researchers found that a magnetic map is responsible for providing sockeye salmon with their keen sense of direction which guides them home, […]
