This CD provides an overview of results from a collaborative analysis of watershed-based threats to the Mesoamerican reef conducted under the International Coral Reef Action Network (ICRAN) Mesoamerican reef (MAR) project. It describes the analysis methodology and presents results of an analysis of estimated sediment and nutrient delivery for over 400 watersheds in the MAR region. The analysis compares sediment and nutrient delivery under current land cover (2003-4) and three potential scenarios of land cover in 2025. The CD includes spatial (GIS) data and metadata for all input data sets, watershed delineations, and model results, as well of maps of the main analysis results.

Although the CD can be used without any GIS software, results are most easily displayed using ESRI ArcView 3.x or ArcGIS 9.x software.
