COS 52-6: Continental-scale dissolved inorganic phosphorus export by rivers: Results from a regional-global modeling approach
ESA Annual Meeting, 94
2009
Abstract
In watersheds, spatial variation in nutrient sources and sinks results in spatial variability of nutrient export ratios and nutrient forms, with important implications for surface fresh water and estuarine ecosystem response. However, past attempts to model global and regional nutrient exports to the coastal zone in a spatially explicit manner have generally ignored within-basin spatial variation in nutrient sources and sinks. We describe, apply and evaluate a new continental-global scale model of dissolved inorganic phosphorus (DIP) transport by rivers called NEWS-DIP-Half Degree (HD), based on a DIP export model developed by the Global NEWS (Global (N) utrient (E) xport from (W) ater (S) heds) work-group. This new model retains half-degree resolution of input variables in analysis and explicitly routes water and nutrients downstream through watersheds, accounting for both DIP sources and DIP sinks along major river systems.
