Shark Migrations Due to the Earth’s Geomagnetic Pathways Stacy Assael Marine Affairs and Policy, M.S. Rosenstiel School of Marine and Atmospheric Science University of Miami

Background There has been evidence of animals using geomagnetism when migrating: Homing Pigeons Monarch Butterflies Salmon Cetaceans

Proposal Sharks are also using geomagnetic pathways located in the earth’s crust to travel long distances across earth’s oceans. www.echeng.com

Methods Attach satellite tags on to pelagic sharks Use Geographic Information Systems (GIS) to plot the shark’s coordinates against a map of the magnetic pathways www.rjd.miami.edu

Goals Understand shark migratory patterns Determine which areas of the oceans sharks are using when migrating Predict shark locations in an attempt to gain more information about their life history
