Do you know how many times have you been swimming at the beach in the vicinity of a great white shark? Thanks to a team called Ocearch, now you can find out if there’s a great white near you. Using GPS-satellite tagging technology, Ocearch is tracking the movement of around 40 great white sharks.
A screenshot from Ocearch’s Global Shark Tracker tool. This shows the path of a great white shark called Mary Lee, who has swum along the east coast as far north as Cape Cod.
You can view the movement of these sharks at the Ocearch Global Shark Tracker website.

The town of Chatham, MA, on Cape Cod, has restricted swimming on its beaches after sightings of several great white sharks. The sharks may have disappointed beach-goers hoping for one last weekend in the water, but they have excited scientists hoping to study the behavior of the sharks.
Scientists were able to affix tags on two of the sharks, marking only the second and third time such a feat was accomplished. The tags will record the sharks’ locations, the temperature of the water, and the amount of light every ten minutes. This data will be recorded until January when the tags will pop off and float to the surface. Once at the surface the tags will send the recorded information to scientists.
The information may prove valuable in understanding the migratory habits of great white sharks.
