MYRTLE BEACH, S.C. - For many people drawn to the ocean by warmer water each year, sharks are the last thing they want to see. But for researchers from Coastal Carolina University who make the annual trek to the coastal waters off Georgetown County, finding healthy sharks are essential.

If shark or stingray populations are declining, it could indicate problems for other species, said Dan Abel, associate professor of marine science at Coastal Carolina University.
