Defining the Northeast ecosystem linkages to management objectives

The Northeast IEA team has developed conceptual models linked to management objectives to support the management of marine natural resources. These objectives are derived from current legislation including the Magnuson-Stevens Fishery Conservation and Management Act, Marine Mammal Protection Act, and the Endangered Species Act.

Defining the Gulf of Mexico Ecosystem

The Gulf of Mexico Integrated Ecosystem Assessment (IEA) team has undertaken several conceptual modeling efforts to elicit subject matter expert opinion and engage stakeholders in conceptualizing the integrated systems of the Gulf of Mexico. The team utilizes a holistic approach for conceptualizing the integrated socio-ecological system in the GoM by incorporating metrics from all areas of the Driver-Pressure-State-Ecosystem Service-Response (EBM-DPSER) framework.

Scientists from the NOAA Alaska Fisheries Science Center have been working with fishermen in Sitka to understand the changes that they are witnessing in their marine ecosystems. These changes include shifts in target and non-target species, predator-prey dynamics, oceanographic and environmental factors, hatchery production, and ultimately fisheries earnings and participation. This graphic represents a summary of those changes and the latest scientific information that is available for them.

Indicator Status and Trends

We evaluate the status of the California Current Ecosystem by interpreting a variety of environmental, biological, economic, and social indicators. Current and historical indicator data are organized categorically, below, with a graphic showing the most recent 5-year trend and status relative to the long-term mean; the graphical interface allows for dynamic plotting and data download options.
