BackgroundThere has been evidence of animals using
geomagnetism when migrating:Homing PigeonsMonarch ButterfliesSalmonCetaceans
ProposalSharks are also using geomagnetic pathways
located in the earth’s crust to travel long distances across earth’s oceans.

MethodsAttach satellite tags on to pelagic sharksUse Geographic Information Systems (GIS) to
plot the shark’s coordinates against a map of the magnetic pathways

GoalsUnderstand shark migratory patternsDetermine which areas of the oceans sharks
are using when migratingPredict shark locations in an attempt to gain
more information about their life history
