This newsletter describes the methods used and the predictions for the 2006 summer ecological conditions in Chesapeake Bay. The forecast focuses on three important elements of the Bay's health-dissolved oxygen (DO), harmful algal blooms (HABs) and changes in bay grass distribution.

EcoCheck is a partnership between the National Oceanic and Atmospheric Administration and the University of Maryland Center for Environmental Science. This newsletter conveys their goals and approach towards improving Chesapeake Bay health. The types of projects on which EcoCheck works are also described in the newsletter.

This edition of Chesapeake Update provides an overview of water quality and aquatic grass conditions over the summer of 2005. An explanation as to why these conditions occurred is provided–largely a combination of a wet spring followed by a dry, calm and relatively warm summer. The observed conditions are compared to those forecast to occur before the summer, and explanations for any differences is provided.

Chesapeake Bay has historically supported extensive bay grass (underwater grasses) meadows (>75,000 ha). However, water quality degradation from increased sediment and nutrient inputs has reduced the areal coverage and depth penetration of bay grasses, with one third of historical distributions remaining (21,648 ha; 1985-2004 mean). Chesapeake Bay underwater grasses are comprised of a variety of freshwater, brackish, and marine species.

This newsletter is the product of the May 2005 Vital Signs workshop, with participants from each of the 11 National Parks within the NCRN. The National Park Service (NPS) is implementing a series of programs designed to provide a stronger scientific basis for management actions. The Inventory and Monitoring (I&M) program was initiated in 1990 to help fulfill this mission.

This newsletter summarizes the main findings of an ecological forecast aimed at predicting changes in aquatic grass area within Chesapeake Bay for the current growing season. This forecast is part of a new initiative of the Chesapeake Bay Program to forecast a range of ecological conditions for the coming summer.

This newsletter summarizes the main findings and methods of a new initiative to forecast ecological conditions of Chesapeake Bay for the coming summer. This year’s forecast focuses on three important elements of the Bay’s health—dissolved oxygen (DO) in the Bay’s mainstem, harmful algal blooms (HABs) in the Potomac River, and changes in submerged aquatic vegetation (SAV) distribution.

Environmental models are essential for simulating ecosystems that are either too large or too complex to isolate to conduct real world experiments. Models allow scientists to simulate changes in an ecosystem due to changes in population, land use, or pollution management.

This is the first in a series of newsletters to be produced by the Monitoring and Analysis Subcommittee (MASC). MASC coordinates and supports the monitoring activities of the Chesapeake Bay Program (CBP). Newsletters produced by MASC will summarize current and significant issues relating to the health of Chesapeake Bay ecosystems, those factors that affect the health of the Bay, and the restoration effort.
