Calculating the 2006 Chesapeake Bay report card scores

Caroline Donovan, Ben Longstaff, Bill Dennison ·
18 April 2007

Ecosystem health report cards are an effective means of tracking and reporting the health of a waterway at both local and regional scales. A report card is being developed within the Chesapeake Bay science and management community in order to provide a transparent, timely, and geographically detailed annual assessment of Chesapeake Bay habitat health. This newsletter summarizes the methods and data used to calculate the report card scores for 2006.

Chesapeake Bay Habitat Health Report Card: 2006 (Page 1)

Chesapeake Bay Habitat Health Report Card: 2006

Ben Longstaff, Michael Williams, Caroline Donovan, Bill Dennison ·
18 April 2007

This report card provides a transparent, timely, and geographically detailed annual assessment of 2006 Chesapeake Bay habitat health. A report card will be released each year, in early to mid April, providing an assessment of the previous year’s habitat health. 2006 is the first year that the report card has been released. This report card rates 15 reporting regions of the Bay using six indicators that are combined into a single overarching index of habitat health.

Beneficial use of dredged material to restore Chesapeake Bay wetlands

Emily Benson, Heather Lane, Jane Thomas ·
23 February 2007

A Mid-Chesapeake Bay Marshlands Restoration project is being developed by the Integration and Application Network, the US Army Corps of Engineers, Maryland Port Administration, US Fish & Wildlife Service, and Maryland Department of Natural Resources. This newsletter discusses the ecological, economic, and engineering issues associated with using dredged material to restore the eroding marshes of the mid-Chesapeake Bay.

An adaptive neural network embedded genetic algorithm approach for inverse water quality modeling (Page 1)

An adaptive neural network embedded genetic algorithm approach for inverse water quality modeling

Zou R, Lung WS, and Wu J ·
2007

This paper proposes a neural network (NN)-embedded genetic algorithm (GA) approach for solving inverse water quality modeling problems to overcome the computational bottleneck of inverse modeling by replacing a water quality model with an efficient NN functional evaluator. An existing one-step, NN-embedded GA approach is found incapable of solving an inverse water quality modeling problem because it tends to fail in guiding the global search process to converge toward the near optima.

The challenge of communicating monitoring results to effect change

Carter SL, Mora-Bourgeois G, Lookingbill TR, Carruthers TJB, and Dennison WC ·
2007

SINCE ITS INCEPTION, the National Park Service (NPS) has been charged with preserving the natural and cultural heritage of the United States for future generations. It is only recently, however, that the NPS has fully embraced the need to understand and describe the ecology of parks. The infusion of an ecological perspective into the natural resource management of the national parks is what separates today's park management from much of that which preceded it (Sellars 1997).

Future directions of fisheries management: An ecosystem-based approach (Page 1)

Future directions of fisheries management: An ecosystem-based approach

Boicourt K, Longstaff BJ and Townsend H ·
1 December 2006

This newsletter describes current and future directions of Ecosystem-Based Fisheries Management (EBFM). While the standard approach to fisheries management has been to focus on one species at a time, EBFM characterizes a greater number of ecosystem components, including the physical and chemical properties of systems. The newsletter explores the current and potential applications of the ecosystem-based approach.

Weather extremes lead to typical conditions

Caroline Donovan, Ben Longstaff ·
9 November 2006

This newsletter addresses the extreme weather conditions that the Bay area experienced during the spring and summer of 2006 and how these weather conditions affected the summer ecological forecast that was released in May 2006 and other aspects of Bay health. The forecast focuses on dissolved oxygen in the mainstem, harmful algal blooms in the Potomac River and aquatic grasses in three locations in the Bay.

Investigating menhaden recruitment variability: Modeling the relationship between striped bass recovery and menhaden recruitment (Page 1)

Investigating menhaden recruitment variability: Modeling the relationship between striped bass recovery and menhaden recruitment

Zhang X, Wood RJ, Wicks EC and Longstaff BJ ·
18 October 2006

This newsletter summarizes ongoing development of a model that describes fluctuations in the number of young menhaden within Chesapeake Bay. Using both menhaden spawning stock and striped bass predation potential, the model successfully accounts for most of the variability (~70%) seen in Chesapeake Bay menhaden recruitment.
