Freshwater Fluxes into the World Oceans from GIWA Regions (GRDC, 2009)

This special application of GRDC's Surface Freshwater Fluxes into the World Oceans (GRDC, 2009) calculates the annual freshwater fluxes from land areas associated with GIWA regions summarizing the individual flux values of the relevant coastline cells.

The associated GIS layer will be provided on request.
