We took a trip to [foggy] Duck Island for a gray seal monitoring survey, and then Mary showed students how to complete abundance estimates and photo ID from photos of haul out sites.  Everyone seemed to enjoy the photo ID process, especially choosing names for seals based on distinguishing marks (photos above).  A large thunderstorm, with lots of lightning, in the afternoon gave way to a double rainbow during dinner.  Around 9:00, the skies lit up with heat lightning as well as fireworks from many towns on the New Hampshire and Maine coasts.
