TL;DR: Improvements in the water quality of many freshwater and most coastal marine ecosystems requires reductions in both nitrogen and phosphorus inputs.

TL;DR: For example, during most summers over the past 30 years, bottom dissolved oxygen across a large area of the Louisiana and upper Texas continental shelf declined to concentrations too low (hypoxia) for most fish and large invertebrate animals to survive as mentioned in this paper.
Abstract: During most summers over the past 30 years, bottom dissolved oxygen across a large area of the Louisiana and upper Texas continental shelf declined to concentrations too low (hypoxia) for most fish and large invertebrate animals to survive. This area is one of the best known “dead zones” proliferating around the world [Diaz and Rosenberg, 2008]. During July 2008, hypoxic bottom waters extended across 20,720 square kilometers (Figure 1), but they were probably even more extensive because winds from Hurricane Dolly mixed the waters off Texas before the survey could be completed.

TL;DR: The Policy Forum has stimulated numerous responses on effective strategies for controlling phosphorus (P) and nitrogen (N) to reduce eutrophication in freshwater and coastal marine ecosystems as discussed by the authors.
Abstract: We are gratified that our Policy Forum has stimulated numerous responses on effective strategies for controlling phosphorus (P) and nitrogen (N) to reduce eutrophication in freshwater and coastal marine ecosystems.

TL;DR: In this article, the authors discuss the challenges that the Gulf Coast is facing due to a national inability to maintain and upgrade both natural and built infrastructure, and propose solutions to these challenges, including funding.
Abstract: A national inability to maintain and upgrade both natural and built infrastructure is reflected in the challenges that the Gulf Coast is facing. Recent storms (2008) and Hurricane Katrina (2005) both revealed fragile regional hurricane defenses and wetland and ecosystem losses that have experienced little or no abatement for more than a century. Protection and restoration of coastal systems are linked efforts, both of which lack strong support, although often extremely slow restoration is being made in New Orleans flood protection systems and coastal deltaic systems. Solutions to these challenges, including funding, are discussed. Paintings by artist John Brosio depicting the power of tornadoes complement the article.
