Watch the video below to learn how swimmers and surfers concerned about sharks can further reduce the chances of being bitten. Shark interactions compared to other risks.
Where shark interactions occur in the United States. Explore the International Shark Attack File to learn more about: The University of Florida’s International Shark Attack File recorded a worldwide total of 64 unprovoked shark bites in 2019, 41 of which were in the United States. It is extremely unlikely for Atlantic swimmers and surfers to be bitten by-or even encounter-a shark. However, there is currently no evidence that sharks are spending more time near shore as a result of warming waters. Some southern species are extending their ranges farther north. Understanding the effects of climate change on sharks and other fish populations is an emerging area of study and a priority for NOAA Fisheries. These species are also found in New England waters, where spiny dogfish and white sharks commonly swim in search of their natural prey.Įxplore Atlantic shark nurseries Is Climate Change Bringing More Sharks Near Shore? In the Mid-Atlantic region, sandbar, sand tiger, and smooth dogfish sharks frequent nearshore waters, especially during the summer. Species like Atlantic blacktip, spinner, Atlantic sharpnose, and lemon sharks can be abundant in the Southeast’s nearshore waters. Others are open-ocean dwellers that use shallower waters as nurseries or occasional feeding grounds. Many species move through bays and estuaries along the U.S. Most Atlantic sharks spend at least part of their lives in coastal waters. These range from the small spiny dogfish to the much larger white shark, and they are found in just about every kind of ocean habitat. "Sharks have probably been doing it for millions of years," says Whitney, "we're learning things that 10 years ago we would have never dreamed we could have learned about these species.The waters off the East Coast are home to more than 50 shark species. The data also revealed that Mary Lee swam all the way to Bermuda - behavior scientists suspect is common among her species. So close, in fact, that the team behind the tracking project called the beach authorities in Florida to warn them about Mary Lee's presence. Since being tagged, Mary Lee has covered most of the Eastern Seaboard, swimming very close to the coastline. Take Mary Lee, a 16-foot 3,456-pound great white that was first tracked last September. "It's just phenomenal," says Whitney, "second by second, we can pick up every tail beat and change in posture." Speaking to Computer World, marine biologist Nick Whitney says the program collected around 100 data points every second - 8.5 million per day. You can click on any of the dots to find a picture of the shark along with its size and "name," and look through where it's been since being tagged. The data is then fed into the OCEARCH Global Tracker, which updates the sharks' location as a dot on a map. 
Some 47 sharks have been tagged with an array of sensors that allow scientists to accurately plot their position. An ambitious project means anyone can now track the movements of almost 50 sharks in realtime.
