FILE – In this Sept. 13, 2012 file photo, researchers screw satellite and acoustic tags onto the dorsal fin of a great white shark on the research vessel Ocearch in the Atlantic Ocean off the coast of Chatham, Mass. Once released, the tags will track the location and speed of the nearly 15-foot, 2,292-pound Genie, named for famed shark researcher Eugenie Clark. Researchers in Massachusetts say great white sharks in the Atlantic Ocean are venturing offshore farther, with more frequency and at greater depths than previously known. The findings were published Sept. 29, 2017, in the scientific journal Marine Ecology Progress Series. (AP Photo/Stephan Savoia, File)
