  • A Twitter user recently saw 100 great white sharks on a tracker up and down the East Coast.
  • Tracker Ocearch said the sighting isn’t unusual or cause for alarm.
  • An increase in tagging sharks and climate change are being floated as theories behind the shark congregation.

A curious Twitter user recently pointed out that when checking the Ocearch great white shark tracker, about 100 of the sharks could be seen up and down the East Coast.

sharks [sic] are amassing on the east coast,” the user wrote, alongside a screenshot.

However, Ocearch issued a statement to The Sun, stating the congregation is common and not a cause for alarm.

“We are currently studying the Northwest Atlantic White Shark, the white sharks that live off the Eastern United States and Canada,” Ocearch said. “This is why we have so many recently tagged sharks in this area. We have tagged 83 white sharks in the NW Atlantic.”

As Ocearch continues to tag and track more great whites, the more will appear on the monitors.

Similarly, experts have pointed to the effects of climate change as additional reasoning for more sharks to frequent these areas.

“This isn’t terribly uncommon since most of these sharks were likely tagged at nearshore locations. Although, this is typically the season when smaller sharks are migrating to warmer southern waters,” Christopher Lowe, director of the Shark Lab at California State University, told The Sun, adding, “Much of this pattern is likely attributed to changing oceanographic conditions caused by climate change.”
