Description:
We are designing an electronic report on coastal conditions in the Northeast (from Delaware to Maine) for release in 2005. The report will be similar in appearance to a chapter on Northeast Coastal Conditions (EPA, National Coastal Condition Report 2), but based on twice as many data, and include computational tools. In designing the report, we plan to utilize "reproducible research" concepts. In addition to text and graphics, "reproducible research" publications include data, metadata, software tools and scripts which help the reader reproduce the statistical and graphical analyses, and interactively explore underlying analysis methods and data structures in more detail. Summary statistics and graphics on National Coastal Assessment (NCA) data will be displayed in an ArcGIS-9 Project along with the underlying data in attribute tables, Excel spread sheets including macros, and other formats. A series of report highlights will provide additional detail illustrating NCA probabilistic sampling designs, simple Excel spread sheet calculations of area-weighted statistics, calculation of confidence intervals, and the use of GIS techniques. Several highlights will illustrate how the NCA data can be combined with other data from targeted monitoring and model output for assessing local conditions. For this talk, we illustrate the approach using: 1) ArcGIS-9, 2) data collected in 2000-2001 by the NCA program for quantifying baseline conditions, 3) additional data from both fixed stations and targeted sampling in Narragansett Bay, and 4) the use of output from the USGS-EPA New England SPARROW Model as input into 5) a nitrogen mass balance model for estuaries.
