DRAFT CHAPTER 1 - INTRODUCTION As directed by the Oceans Act of 2008, the Massachusetts Executive Office of Energy and Environmental Affairs (EEA) is developing a comprehensive ocean management plan in Commonwealth waters. The Oceans Act requires the establishment of an ocean Science Advisory Council (SAC) of nine members with expertise in marine sciences to support the Secretary of Energy and Environmental Affairs in the development of the ocean management plan. The SAC was tasked with creating a baseline assessment and obtaining any other scientific information necessary for the development of the ocean management plan. Specifically, the SAC assisted in the development of the baseline assessment by approving the outline, reviewing data sources provided by the authors, providing additional data sources, and editing drafts for clarity and content. This document is the baseline assessment portion of the Massachusetts Ocean Management Plan. It is intended to be an information base for ocean management plan development and implementation and to provide a science-based context for the plan. The introduction covers how the data were assembled for the assessment and the geographic focus for the ocean management plan. Chapters two through eight describe the current knowledge and status of resources, uses, and conditions in the Massachusetts ocean management planning area. DATA COLLECTION Many sections of this baseline assessment are informed by The Massachusetts Ocean Management Task Force Technical Report (Commonwealth of Massachusetts 2004). In addition, the baseline assessment incorporates new information produced by the six ocean management plan working groups that were formed to help inventory and synthesize available data for the development of the ocean management plan (i.e., the habitat; fisheries; renewable energy; transportation, navigation, and infrastructure; regional sediment resource management; and ocean recreational and cultural services work groups). These work groups were organized following the signing of the Oceans Act and worked through the summer and fall of 2008. The work groups included a core of state agency staff that compiled existing data and spatial information on the various topics. After the initial data collection phase, the work groups were expanded to include expertise from beyond state government that included academia, federal agencies, non-profit organizations, and industry. The work group process resulted in a series of reports that describe and analyze existing data for each of the six topic areas. While the work group reports are stand-alone products, as appropriate, data and analysis results have been incorporated into this baseline assessment. Data variability is a readily apparent issue with this baseline assessment. Within the ocean management planning area (planning area), available data varies spatially, temporally, and in terms of depth, precision, and accuracy for most subjects covered in this baseline assessment. In the future, one of the important ocean management activities will be DRAFT BA-1 addressing data variability and filling data gaps, particularly for priority issues and management concerns. For purposes of this document, “baseline” is not intended to connote a description
