Nitrogen, phosphorus, and silicon inputs to coastal waters (COSCATs and LMEs)

Pre-industrial and contemporary sources of nitrogen (N), phosphorus (P), and silicon (Si) to the coastal ocean for COSCATs and LMEs. Sources of N include rivers, net upwelling, net onwelling, atmospheric deposition, N2 fixation, and submarine groundwater flow. Sources of P include rivers, net upwelling, net onwelling, and atmospheric deposition. Sources of Si include rivers, net upwelling, and net onwelling.
