Maps for Planning

The Northeast Ocean Data Portal for Coastal and Marine Spatial Planning (CMSP)

The Northeast Ocean Data Portal for CMSP is a decision support and information system for managers, planners, scientists and project proponents involved in coastal and marine spatial planning in the region from the Gulf of Maine to Long Island Sound. The Portal provides access to data, interactive maps, tools, and other information needed for decision making. The primary audiences for this effort include regional managers, ocean stakeholders, and technical staff participating in CMSP, although the information is useful in other ocean management and industry contexts. The Portal builds on existing efforts in the region and provides additional capacity for both state- and regional-level CMSP.

Working Group

A partnership of government agencies, non-government organizations, and academic entities is developing and maintaining the Northeast Ocean Data Portal.  The Working Group is an open membership collaboration of organizations with a desire to create a collective environment for sharing data, ideas, tools, and information to support CMSP.  We encourage organizations and stakeholder groups interested in the advancement of CMSP, and its related products and policies, to contact the Working Group and take part in this initiative.  This effort builds upon existing regional capacity, with broad participation from organizations throughout the Northeast, and significant Working Group investments.  The Working Group is facilitated by a chaired steering committee composed of the Massachusetts Ocean Partnership, the Northeast Regional Ocean Council (NROC), The Nature Conservancy, the Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS), NOAA Coastal Services Center, and Applied Science Associates.  Since the launch of the Data Portal in June 2011, Working Group efforts have focused on continued advancement of NROC-identified priorities, including the integration of key datasets for CMSP and the development of functionality to access, visualize, and analyze those data.
