Scientists say the increased shark activity could be our new normal. More sharks can indicate a healthier ocean and there is groundbreaking research underway in our area to catch, track and better understand these misunderstood predators of the deep. For the latest on these efforts and how to stay safe this summer we’re joined by Frank Quevedo, executive director of South Fork Natural History Museum, which oversees a shark research and education program; Greg Metzger, the program’s field coordinator who has caught and tagged hundreds of sharks; and Lt. Brian Matteo, a member of the New York State Park Police’s marine unit that patrolled for sharks.
