Natal Homing - Forward

Forward

Although scientists have been studying marine animals that perform natal homing for years, they are still not positive that geomagnetic imprinting and chemical cues are the only navigational tools they use for their incredible migrations. There is still much more research to be done until scientists can fully understand how these animals can travel such great distances to reproduce. Fortunately as technology has progressed there are several tools available to scientists now such as data loggers equipped with magnetometers that can easily be attached to the animals. Not only do they give data showing the animal relative to the Earth's magnetic field but some also give latitude based on this, longitude based on light levels, temperature, depth, etc. Pop-up satellite archival tag are used to gather data anhave the ability to transfer this data via Argos System satellites to the scientist.
