Sources and fate of nitrate in a groundwater-fed estuary elucidated using stable isotope ratios of nitrogen and oxygen
nitrate oxygen isotope
2014/10/16
We used d15N-nitrate (NO{
3 ) and d18O-NO{
3 to unravel the provenance and fate of NO{
3 in a groundwater-fed
estuary. A total of 13 monthly and two time series surveys were undertaken in the Werr...
