Track A Great White Shark

The OCEARCH's Global Shark Tracker shows real-time navigational patterns of sharks marked with satellite tags.

Right now, there are massive great white sharks off the coasts of Jacksonville, Florida and Nantucket, Massachusetts. 

We know this, partly, because of OCEARCH's Global Shark Tracker.

OCEARCH supports researchers studying ever-growing data on the biology and health of these sharks, in conjunction with basic research on shark life history and migration.

The researchers work aboard the M/V OCEARCH, a unique 126-foot vessel equipped with a custom 75,000 hydraulic lift and research platform.

The Global Shark Tracker program allows internet viewers to observe the navigational pattern of sharks that have been tagged with satellite tracking technology.

And the results are pretty interesting. 

That shark off Jacksonville ... her name is Mary Lee and she weighs about 3,500 pounds.

She's heading to warmer waters to winter near the Georgia and Florida coastline.

Meanwhile, Genie, another white shark tagged off Cape Cod, has stayed in the New England area.

In this map, the track shows the movement of white shark Mary Lee in recent days.

Not all regions with white sharks are covered by OCEARCH. If you check the map, you'll notice a lack of tags on the West Coast of United States and in Australia, areas known for great white encounters. The coast of South Africa is the most-covered, jumbled with tags from great whites.
