MASC Newsletter 2 - Ecological Forecast, Summer 2005

Ben Longstaff, David Jasinski ·
1 May 2005

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.

MASC Newsletter 1 - Water Quality 2004

Ben Longstaff ·
1 January 2005

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.

Crassostrea ariakensis: Panacea or Pandora? (Page 1)

Crassostrea ariakensis: Panacea or Pandora?

Adrian Jones, Tracey Saxby ·
1 March 2004

This newsletter is based on research conducted by Dr Mark Luckenbach and a presentation he gave at the Chesapeake Bay Seminar Series in July 2003. The introduction of Crassostrea ariakensis into Chesapeake Bay has been proposed for both economic and ecological gain. Data exists suggesting that C. ariakensis grows significantly faster and is more resistant to the diseases that have devastated the native oyster.

Nutrient Management of Delmarva Soils & Waters

Jane Thomas ·
1 March 2004

This newsletter is based on the 'Status of nutrients in Delmarva soils, groundwaters, creeks and tributaries forum', October 21, 2003. Extensive poultry operations and associated feed grain production on the Delmarva Peninsula have resulted in elevated nutrient levels in soils, groundwater, creeks and tributaries of the Chesapeake Bay.

Developing a Chesapeake Bay Report Card

Adrian Jones, Jane Thomas ·
1 November 2003

This newsletter details the importance of developing a scientifically rigorous, spatially explicit ecosystem health report card on Chesapeake Bay and its watershed to facilitate coordination and feedback between monitoring, management and research. A pilot study was conducted in July 2003 on the Patuxent and Choptank Rivers using a novel stable isotope technique (see "Assessing Nutrient Sources" newsletter below) together with more traditional water quality monitoring techniques.

Phragmites: Native or Introduced (Page 1)

Phragmites: Native or Introduced

Tracey Saxby ·
1 November 2003

This newsletter describes the historical distributions of both native and introduced Phragmites. It details the invasion of the introduced type in North America (determined through genetic analysis), and morphological differences between the native and introduced types, as well as some commonly used control methods and their associated problems. Phragmites is thought to be one of the most widespread plants on earth.

Conceptual Diagrams: Tools for Science Communication

Adrian Jones, Tracey Saxby ·
1 August 2003

This newsletter details the use of symbols as a visual language. Symbols are useful for depicting unequivocal messages that transcend cultures, languages and times. The use of symbols to contruct conceptual diagrams ('thought drawings') can be an effective tool for science communication and problem solving. Conceptual diagrams help to clarify thinking and provide a communication interface between scientists and non-scientists.

Assessing Nutrient Sources (Page 1)

Assessing Nutrient Sources

Adrian Jones, Tracey Saxby ·
1 February 2003

This IAN newsletter explores the assessment of nutrient sources using stable isotope signatures of various marine organisms. This technique was developed in Moreton Bay, Australia for mapping sewage plumes, and was also used to determine the extent of aquaculture effluent (shrimp ponds) and to distinguish agricultural runoff (sugar cane) from other sources. The stable isotope ratio of nitrogen in organisms can be used to determine the influence of different nitrogen sources.
