Great White Shark Travels 19,000 Miles in One Year
Wow, this is fascinating, 19,000 miles!
A great white shark called Lydia is set to make history. First tagged a year ago off the Florida coast, she’s on her way to becoming the first tracked white shark to cross the Atlantic.
Lydia is being monitored by the marine nonprofit Ocearch as part of its ongoing project to help researchers and scientists gather previously unattainable data on shark movement, biology and health. The 14-foot-6-inch great white has migrated more than 19,000 miles since being tagged.
The Ocearch team uses two different kinds of electronic tags, Skomal explained. One is a pop-up satellite tag that can archive data such as depth and light levels. The tag can be programmed to release from the shark and then float on the water surface to transmit data back to the scientists.
Another is a real-time satellite tag, which connects to a satellite whenever the shark comes to the surface, providing data about the shark’s movements so scientists — and the public — can follow a shark’s migration patterns over a long time. This is what Lydia has.
I can’t wait to hear more about what’s learned here.
