Researchers tag sharks off New York's Hamptons to study migration and local nursery
Marine scientists are deploying acoustic and temperature trackers to monitor great white shark development and track southern species migrating into warming waters.
The short version
- Marine researchers off Southampton, New York, are catching, tagging, and releasing sharks to gather data on coastal movements and local marine habitats.
- The initiative focuses on examining a known great white shark nursery in the shallow coastal waters off Long Island, alongside tracking tropical species moving north during summer months.
- Researchers note that increased shark sightings stem primarily from improved observation technology, such as consumer drones and smartphones, rather than a population surge.
- Scientists plan to continue monitoring acoustic signals and data-logging tags as animals migrate south for the winter before returning the following year.

- The research focuses on studying shark behavior within a confirmed great white shark nursery, one of only a few globally recognized alongside areas off California, Mexico, and Australia.[Associated Press · ABC News]
- Scientists use acoustic tags detected by coastal receivers and pop-off devices that record depth and water temperature for several months.[Associated Press · ABC News]
- Tracking data shows sharks migrate long distances down to North Carolina, Georgia, Florida, and the Gulf of Mexico before returning to Long Island the next year.[Associated Press · ABC News]
- According to the International Shark Attack File, there are no recorded fatal shark attacks on Long Island, though recent non-fatal bites have prompted local drone monitoring efforts.[Associated Press · ABC News]
What remains uncertain
- The full extent to which climate change-driven water warming is accelerating the northern shift of tropical shark species into New England waters remains under study.[Associated Press · ABC News]
