Overview: Commission on Ocean Policy’s report Ecosystem Science Capabilities (USCOP, 2004), and the Administration’s response to that report Required to Support NOAA’s in the U.S. Ocean Action Plan (CEQ, Mission in the Year 2020 2004). Acting through its Ecosystem Goal The mission of the National Oceanic and Team (http://.ecosystems.noaa.gov), Atmospheric Administration (NOAA) is NOAA has begun to better integrate the to understand and predict changes in the ecological research, observing, and Earth’s environment and conserve and forecasting components undertaken by manage coastal and marine resources to its “line offices” (i.e., NOAA Fisheries, meet our nation’s economic, social and NOAA National Ocean Service, NOAA environmental needs (NOAA, 2004). In Research, NOAA Satellites and meeting its marine stewardship Information Service, and NOAA responsibilities, NOAA seeks to ensure National Weather Service). NOAA’s the sustainable use of resources and five-year research plan (NOAA, 2005b) balance competing uses of coastal and emphasizes how the agency will better marine ecosystems, recognizing both integrate its current activities, using the their human and natural components Goal Team structure as a framework. In (NOAA, 2004). Authorities for contrast, its 20-year vision for science executing these responsibilities come and research encompasses broad themes from over 90 separate pieces of Federal for the agency in meeting its ecosystem legislation, each with unique stewardship responsibilities, as “NOAA requirements and responsibilities. Few will provide the scientific underpinnings of these laws explicitly mandate an for an ecosystem approach to ecosystem approach to management management of coastal and ocean (EAM) or supporting science. However, resources, so that complex societal resource managers, the science choices are informed by comprehensive community, and increasingly, the public, and reliable scientific information” are recognizing that significantly greater (NOAA, 2005c, p. 6). connectedness among the scientific disciplines is needed to support The agency needs to know what types of management and stewardship science, skills, and products will be responsibilities (Browman and Stergiou, necessary to inform emerging ecosystem 2004; 2005). Neither NOAA nor any management challenges if it is to move other science agency can meet the from simply better integrating its current increasing demand for ecosystem activities to meeting its strategic 20-year science products addressing each of its research vision. This document was mandates individually. Even if it was developed to identify a strategic possible, doing so would not provide the portfolio of research, monitoring, data integration necessary to solve the integration, and decision support increasingly complex array of capabilities underpinning more holistic management issues.

For purposes of this discussion Ecosystem science supporting these concerning the scientific support characteristics must therefore be necessary for an EAM, NOAA defines integrated on appropriate geographic an EAM as: scales relevant to the particular problem or issue being addressed. Some of these An ecosystem1 approach to management management foci will be local (e.g., a (EAM) is one that provides a bay or estuary), while many others will comprehensive framework for living scale upwards, including a global scale. resource decision making. In contrast to All will require greater integration of individual species or single issue ecosystem knowledge across traditional management, EAM considers a wider disciplines that can be easily range of relevant ecological, reassembled at problem-relevant time environmental, and human factors and space scales. Given the wider bearing on societal choices regarding diversity of stakeholder groups that will resource use. participate in ecosystem-level problem solving, new information products - EAM is differentiated from more including those that integrate and narrowly focused management by a simultaneously interpret biological, number of defining characteristics. social, and physical trends - must EAM is: (1) geographically specified, (2) emerge.

Climate-driven variability of northward biogeographical shift in environmental conditions is manifest on response to changing temperature and many time and space scales, including atmospheric forcing (Overland and year-to-year variation, multi-year (e.g., Stabeno, 2004; Grebmeier et al., 2006), El Niño-Southern Oscillation [ENSO]), and in the North Atlantic many marine and decadal scales (e.g., Pacific Decadal fish species have been observed to shift Oscillation, North Atlantic Oscillation, their distributions poleward in response and Arctic Oscillation).

NOAA’s Strategic Plan is to “protect, restore and manage coastal and ocean resources through an ecosystem The NOAA Perspective on approach” (NOAA, 2004). This goal Management of LMRs flows from the mandates and direction of such Federal laws, executive orders, There are more than 90 Congressional courts, and international treaties as the laws, treaty obligations, executive Magnuson-Stevens Fishery and orders, regional agreements, NOAA- Conservation Management Act specific policies, memoranda of (MSFCMA), Endangered Species Act understanding with other Federal (ESA), National Environmental Policy agencies, and court orders that drive the Act (NEPA), Marine Mammal requirements of NOAA’s Ecosystem Protection Act, Coral Reef Conservation Mission Goal (NOAA, 2005c). Over the Act, Coastal Zone Management Act, last 20 years, NOAA has worked to National Marine Sanctuaries Act, establish the scientific underpinning for International Commission for the an ecosystem approach to management Conservation of Atlantic Tunas, and (EAM) of coastal and ocean LMRs, so Inter-American Tropical Tuna that complex societal choices are Commission.

types of products and services NOAA many national and international intends to provide to constituents and organizations. By necessity, it requires agency managers include: (1) forecasts discourse between researchers and and mitigation strategies related to managers, and in the future, NOAA will harmful algal blooms (HABs), invasive need to increasingly incorporate species, and air and water quality; (2) constituent input into this discourse. ecological assessments and predictions The key assumption under this approach of impacts from climate change on ocean is that management tools that do not productivity (e.g., coral bleaching and perform well in computer simulations loss of sea ice in the Bering Sea; see are very likely to fail in the real world. White Paper #1); (3) decision support That doesn’t mean that management tools for adaptive, ecosystem-based tools that perform well will necessarily management of fisheries, other marine produce satisfactory results in the real resources, and coastal development; (4) world, but they are certainly more likely improved assessments of sea level to be successful than non-tested change on coastal resources and management approaches. One form of ecosystems; (5) better integration of decision support tools used to evaluate observing system data for use by the impacts of harvest policy is a managers responsible for the health of management strategy evaluation (MSE). coastal ecosystems; and (6) fishery NEPA requires that agencies conduct productivity forecasts incorporating the this type of review to provide public effects of climate change. disclosure of potential impacts of management actions. The MSE is an For each of these products (e.g., attempt to provide quantitative, rather forecasts, assessments, decision support than qualitative, information for tools), it will be necessary to take decision-makers. Thus, NOAA account or otherwise incorporate scientists play a crucial role in the uncertainty associated with parameter process by providing the analysis tools estimation and process error (e.g., and forecasts that will facilitate uncertainty of how a change in one collaborations among managers, component of an ecosystem influences researchers, and constituents to the others). This is typically done by encourage the development of policies evaluating the performance of competing with full knowledge of the necessary approaches using output from computer tradeoffs between the likelihood of simulations that are run under a wide sustainable use of a LMR, its range of scenarios (FAO, 2003).
