Integrated Ecosystem Assessment (IEA)

NOAA Institutional Repository

The NOAA Integrated Ecosystem Assessment (IEA) Program is a NOAA-wide initiative that oversees the direction and execution of Integrated Ecosystem Assessments within the United States ocean and coastal ecosystems. NOAA IEA is an approach that integrates all components of an ecosystem, including humans, into the decision-making process so that managers can balance trade-offs and determine what is more likely to achieve their desired goals. This approach provides the science necessary to carry out Ecosystem-Based Management and is a key part of NOAA’s ecosystem science enterprise. The program has a commitment to ensure the best available science is used to inform management decisions. The program does this by implementing an iterative multi-step approach that provides a framework to support ecosystem-based management - leveraging and integrating existing science and research activities and programs in NOAA and also building additional capacity within the IEA program to assess a marine ecosystem as a whole to provide natural resource managers with a broader understanding of the ecosystem and make fully informed decisions. The program strives to be inclusive, building a constantly growing interdisciplinary network of science and management partners both internal and external to NOAA.

    Local-scale projections of coral reef futures and implications of the Paris Agreement
    van Hooidonk, Ruben ;
    Maynard, Jeffrey
    2016 | Scientific Reports, 6, 39666.
    Increasingly frequent severe coral bleaching is among the greatest threats to coral reefs posed by climate change. Global climate models (GCMs) project great spatial variation in the timing of annual severe bleaching (ASB) conditions; a point at which reefs are certain to change and recovery will be limited. However, previous model-resolution proje ...

    Surface slicks are pelagic nurseries for diverse ocean fauna
    Whitney, Jonathan L. ;
    Gove, Jamison M.
    2021 | Sci Rep 11, 3197
    Most marine animals have a pelagic larval phase that develops in the coastal or open ocean. The fate of larvae has profound effects on replenishment of marine populations that are critical for human and ecosystem health. Larval ecology is expected to be tightly coupled to oceanic features, but for most taxa we know little about the interactions bet ...

  • How Life History Characteristics and Environmental Forcing Shape Settlement Success of Coral Reef Fishes
    How Life History Characteristics and Environmental Forcing Shape Settlement Success of Coral Reef Fishes
    Wong-Ala, Jennifer A. T. K. ;
    Comfort, Christina M.
    2018 | Frontiers in Marine Science, 5, Unsp 65.
    Larval settlement is shaped by the interaction of biological processes (e.g., life history strategies, behavior etc.) and the environment (e.g., temperature, currents etc.). This is particularly true for many reef fishes where larval stages disperse offshore, often spending weeks to months in the pelagic realm before settling to shallow-water reefs ...

    Kearney, Kelly A. ;
    Bograd, Steven J.
    2021 | Front. Mar. Sci. 8:622206
    Climate change may impact ocean ecosystems through a number of mechanisms, including shifts in primary productivity or plankton community structure, ocean acidification, and deoxygenation. These processes can be simulated with global Earth system models (ESMs), which are increasingly being used in the context of fisheries management and other livin ...

    Kearney, K. A. ;
    Alexander, M.
    2021 | Journal of Geophysical Research: Oceans, 126, e2021JC017545
    Seasonal sea ice plays a key role in shaping the ecosystem dynamics of the eastern Bering Sea shelf. In particular, it leads to the formation of a characteristic pool of cold water that covers the bottom of the shelf from winter through summer; the extent of this cold pool is often used as a management index for distribution, productivity, recruitm ...
