presents The Planet Seminar Series

The Planet Ocean Seminar Series offers an op por tu ni ty for the greater Wilmington community to benefi t directly from the topics of in for ma tion available to the Center in its study areas.

The Planet Ocean Seminar Series is free and open to the public. The seminar is held in the main auditorium at the UNCW Center for Marine Science, 5600 Marvin K. Moss Lane. The seminar will begin promptly at 6:30 p.m. in the auditorium. A reception with light hors d’oeuvres will follow.

Due to limited seating, reservations are required. Advanced registration for Blue Fish Society mem- bers will begin April 13, 2005. The general public may begin registration on April 14, 2005.
