Researchers hope to place tags on seven gray seals this week off Chatham and Wellfleet. It will be the first such tagging on adult gray seals in U.S. Atlantic waters, and scientists hope it will answer many of the questions they share with local residents and fishermen about these large marine mammals. Waring hopes the tagging data will begin to answer questions such as where adult seals go when they leave the beach, how deep they dive, what they feed on and whether they are shuttling back and forth between the large Canadian seal colonies off Nova Scotia or north in the St. Lawrence River. continued @ capecodtimes
