30 June 2010

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2009 Coastal Bays health. Coastal Bays health is defined as the progressof four water quality indicators (TN, TP, Chl a, DO) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals. The six indicators are combined into one overarching Coastal Bays Health Index, which is presented as the report card score.

This report card provides a transparent, timely, and geographically detailed assessment of 2008 Coastal Bays’ health. Prepared annually, the report card rates six reporting regions of the Coastal Bays, using six indicators combined into a single overarching index of health. Health is defined as progress towards established scientifically derived ecological thresholds or goals. The overall health of Coastal Bays was moderate in 2008, obtaining a grade of C+.

Shifting Sands: Environmental and cultural change in Maryland

Shifting Sands: Environmental and cultural change in Maryland's Coastal Bays

William C. Dennison, Jane E. Thomas, Carol J. Cain, Tim J.B. Carruthers, Matthew R. Hall, Roman V. Jesien, Catherine E. Wazniak, & David E. Wilson ·
8 June 2009

Referring to both the dynamic nature of the barrier islands forming the coastal lagoons of Maryland’s Atlantic Ocean coastline and also the changing cultural landscape, Shifting Sands is a richly illustrated, multi-authored introduction to Assawoman Bay, Isle of Wight Bay, St. Martin River, Sinepuxent Bay, Newport Bay, and Chincoteague Bay.

Upstream land use affects water quality in Maryland

Upstream land use affects water quality in Maryland's Coastal Bays

Coastal lagoon ecosystems across the Delmarva Peninsula are rapidly evolving due to changing land use patterns and shifts towards intensive agriculture, particularly poultry production, and intensive rural-resi­dential development. These changes in the coastal lagoon seascape are especially evident in the northern Coastal Bays watershed of St. Martin River.

Fine scale patterns of water quality in three regions of Marylands Coastal Bays: assessing nitrogen source in relation to land use (Page 1)

Fine scale patterns of water quality in three regions of Marylands Coastal Bays: assessing nitrogen source in relation to land use

2 April 2008

Intensive sampling of the Maryland Coastal Bays in May and July of 2007 served to further assess spatial patterns in nutrients, responses of biological indicators, seasons, land use, and nutrient cycling. Trends indicated degraded water quality, high tubidity, increasing total nitrogen and phosphorus concentrations, high natural isotope abundance (δ15N), and low dissolved oxygen. The abundance of crop agriculture and development of the St.

Biological indicators enhance water quality monitoring in Maryland

Biological indicators enhance water quality monitoring in Maryland's Coastal Bays

2 March 2007

Nutrient point sources such as wastewater treatment plants and non-point sources including agricultural runoff degrade the water quality of Maryland's Coastal Bays through excessive nutrient loading. Identifying specific sources is difficult due to their variety and mixture. Biological indicators can identify nitrogen sources, integrate nitrogen from these sources over time, and detect biologically important nutrients.

The role of benthic communities in the health of Maryland

The role of benthic communities in the health of Maryland's Coastal Bays

2 February 2007

In collaboration with the University of Maryland's Cooperative Extension Service at the Wye Mills Research and Education Center, EcoCheck (NOAA - UMCES partnership) has produced a newsletter on the history and current trends of benthic communities in Maryland's Coastal Bays. Aquatic grasses and shellfish are important components of a healthy ecosystem because they provide a variety of ecosystem services, improve water quality, and are commercially valuable.

Linking water quality to living resources in a mid-Atlantic lagoon system, USA (Page 1)

Linking water quality to living resources in a mid-Atlantic lagoon system, USA

Wazniak CE, Hall MR, Carruthers TJB, Sturgis B, Dennison WC, and Orth RJ ·
2007

The mid-Atlantic coastal bays are shallow coastal lagoons, separated from the Atlantic Ocean by barrier sand islands with oceanic exchanges restricted to narrow inlets. The relatively poor flushing of these lagoon systems makes them susceptible to eutrophication resulting from anthropogenic nutrient loadings. An intensive water quality and seagrass monitoring program was initiated to track ecological changes in the Maryland and Virginia coastal bays.

Water quality in four regions of the Maryland Coastal Bays: assessing nitrogen source in relation to rainfall and brown tide (Page 1)

Water quality in four regions of the Maryland Coastal Bays: assessing nitrogen source in relation to rainfall and brown tide

1 November 2006

Monitoring water quality and determining nutrient inputs is essential to assess ecosystem health. Partnering with the Maryland Coastal Bays Program and the Department of Natural Resources, this study focused on four regions in Maryland's Coastal Bays. These regions, St Martins River, Public Landing, Johnson's Bay, and Chincoteague Island, were found to be nitrogen 'hotspots' by the 2004 water quality assessment study.

This data report details the results of an intensive sampling effort by the Integration and Application Network in the Maryland Coastal Bays. A spatially explicit Water Quality Index was developed from standard water quality analyses and a relatively new stable isotope technique.
