The Geographic Information Systems and Ocean Mapping in Support of Fisheries Conference evolved from a commitment by Chrys Chryssostomidis, Director of the Massachusetts Institute of Technology Sea Grant College Program and John Boreman, Director of the Northeast Fisheries Science Center NOAA/NMFS to identify ways to collaborate on geospatial mapping in support of fisheries management. A Steering Committee representing a broad spectrum of organizations and agencies was invaluable in identifying themes, recommending speakers, and providing advice for framing the discussions. The structure included presentations and posters by participants. The success of the workshop was not only due to the excellent input from the speakers and poster presenters, but also from the networking and animated conversations among the attendees.
