The workshop is a key component of a reassessment of the science underlying the Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico that was adopted by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force in October, 2000. The activities of the Upper Mississippi River Sub-basin Hypoxia Nutrient Committee are intended to achieve a near-term goal of a technically sound and economically viable nutrient reduction strategy for the Upper Mississippi River Sub-basin and a long-term goal of reducing nutrient loadings to streams and lakes within the five states and to the Northern Gulf of Mexico which will, in turn, address the coastal, within Basin, and quality of life goals of the Action Plan.

Management of the northern Gulf of Mexico large hypoxic zone is driven primarily by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force ("Hypoxia Task Force") Action Plan. Both the 2001 and revised 2008 Action Plans called for a reduction in the average areal extent of the hypoxic zone to 5000 km2 by the year 2015, less than 1/3 the current typical annual maximum area. To achieve this goal, watershed nutrient loading reductions of 45% total nitrogen and 45% total phosphorus were estimated needs. The science to inform these targets and develop hypoxia mitigation strategies was derived from predictive models based on the quantitative relationship between causative factors (e.g. nutrient loading, stratification) and extent of hypoxia, long-term monitoring, and forecast models to test the validity of predicted relationships. This science provided the foundation for an evaluation by an Environmental Protection Agency Science Advisory Board Hypoxia Advisory Panel which served to update and synthesize research efforts on the causes and consequences of the hypoxic zone and assess progress in implementing nutrient reduction measures in the Mississippi River watershed. This information subsequently led to the adoption of the 2008 Action Plan by the Hypoxia Task Force.

Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot s- port marine life, generally manifests itself in the spring. Since marine species either die or ee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational shing in the Gulf. Since 2001, the hypoxic zone has averaged 2 1 16,500 km during its peak summer months , an area slightly larger than the state 2 2 of Connecticut, and ranged from a low of 8,500 km to a high of 22,000 km . To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together represen- tives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Of ce of Science and Technology Policy to conduct a scienti c assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR).

ABSTRACT: The Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico represents the first national attempt to address this environmental issue. Hypoxia is the condition of low concentrations of dissolved oxygen in a body of water. This condition leads to a so-called dead zone and potentially threatens industries dependent on the living marine resources of this area. The potential impact of any policy or plan designed to combat hypoxia in the Northern Gulf of Mexico could have significant impacts on stakeholder groups, specifically the fishing industry in the Gulf of Mexico, and the agriculture and fertilizer industries in the Midwest. This thesis examines the influence of the relative economic power of the aforementioned industries on the development of effective policy to mitigate hypoxia. The relative economic power of the agriculture and fertilizer industries has significantly impacted the development and efficacy of this plan.
