These data are a compilation of currently available seagrass GIS data sets for the west coast of the United States. These data have been compiled from seventeen different data sources. The source data were acquired over a large range of time periods, at many different spatial resolutions using a variety of methods, including aerial photography, videography, multispectral sensors, sonar, and field surveys.
Users are cautioned to use these data as only a regional view of seagrass locations. Areas without mapped seagrass may contain seagrass, but digital data were unavailable during this data compilation.
