Magnetic Lineations

Magnetic Lineations

September 28, 2016

        I believe it is accurate to say in the marine world there are animals able to understand their sensitivity to the earth’s magnetic field. For instance the loggerhead sea turtles, Kenneth and Catherine Lohmann of the University of North Carolina at Chapel Hill and their team have done several experiments that have shown the loggerhead sea turtles do use the earth’s magnetic field as a compass. Loggerhead sea turtles can detect not only the field’s intensity but its inclination.

 

        As described by a British biologist named Margaret Klinowska and Joe Kirschvink of the California Institute of Technology. Whales also follow the same senses along with these magnetic lineations during migration. The problem with following magnetic lineations is magnetic anomaly do exist, as they are not always true. If the whale becomes off track while following the magnetic lineations and follows a sharp magnetic anomaly that curves and runs into the coast, bang, you end up on the beach. Hence the reason why whales become beached. Whales follow the leader and as in all species of life mistakes happen.

 

        Have you ever thought what it would be like to have the ability to follow a magnetic lineation? The benefit for humans to be able to sense the magnetic field is we wouldn’t have to solely rely on a compass but just know where we were and how to get back to where we started. When we move to a new area or go looking for that job interview downtown, we would know exactly how to get there. Hikers would be able to continue down a broken trail or create their own personal trail to get where they wish to be. Sailors can sail to their hearts content to find their destination. We would no longer need the services of goggle maps or paper maps for that fact.

Food for thought!
