Since then, Canada’s gray seals have returned to recolonize the east coast of the U.S.,,, Now, in a study published in Bioscience, researchers have combined Google Earth images and data from tagged seals to make a more precise estimation of the population.,, “Our technology-aided aerial survey, which used Google Earth imagery in conjunction with telemetry data from tagged animals, suggests the number is much larger—between 30,000 and 50,000.” Not everyone is happy with the pinniped’s population explosion—particularly fisherman, who see them as competition for fish stocks. In recent years, some groups have advocated for culling the number of gray seals.
