J Sharples, JJ Middelburg, K Fennel… - Global …, 2017 - Wiley Online Library
Globally, rivers deliver significant quantities of nitrogen (N) and phosphorus (P) to the
coastal ocean each year. Currently, there are no viable estimates of how much of this N and …

Habitat‐specific distinctions in estuarine denitrification affect both ecosystem function and services

MF Piehler, AR Smyth - Ecosphere, 2011 - Wiley Online Library
