Scientists at the University of Miami studied tiger shark migration data and compared it with temperature changes in the ocean.
Scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science conducted the study by analyzing nine years of tracking data tagged tiger sharks. The team also compared that data with forty years worth of conventional tag and recapture data collected by the National Oceanic and Atmospheric Administration (NOAA).
Neil Hammerschlag, direct of the UM Shark Research and Conservation Program, said, "Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures. These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing."
