Marine Animals Tracking: Tuna Tagging 5-image photo collage strip

Stanford’s Hopkins Marine Station, led by Professor Barbara Block, has been pioneering
the use of novel navigation tags to study the migratory behavior of large marine
animals—especially tuna, sharks, billfish and turtles. 

The GPS Lab and SCPNT have recently teamed with Hopkins Marine to develop a GPS tag that can provide a marine animal’s GPS position location in near real-time.  The tag, when activated, transmits the animal’s position using satellite phone (satphone) technology. The tag is being developed to detect illegal shark fishing. This technology can also be applied to protect and track other marine species.
