Some additional information for River Discharge to the Coastal Ocean: A Global Synthesis Note that the data contained in the electronic files is only the location of the river mouths and the data associated with each watershed. There are many freely available coastline files available for use with a GIS system. Metadata: (also included in an html file within the shapefile folder) What does this data set describe? Title: River Discharge to the Coastal Ocean: A Global Synthesis Abstract: This is the location of the mouths of the rivers in the Milliman and Farnsworth (2010) database. Each location has associated with it information regarding the characteristics of the watershed and the water and sediment discharge. 1. How should this data set be cited?
