It’s early on a weekday morning, and Chris Pincetich is sifting through a small pile of debris on Stinson Beach. He’s at the high-water mark, called the wrack line. That’s where buoyant ocean flotsam gets stuck as the tide goes out. As we walk along, he stops and points out how plastic strapping looks a lot like weathered eelgrass. Pincetich isn’t your ordinary beachcomber. He’s a scientist trying to compile a local data set for a global problem: marine plastic pollution.
