Nitrous oxide (N2O) measurements in the surface water of the Elbe Estuary in 2015 Lisa Brase, Hermann Werner Bange, Ralf Lendt, Tina Sanders, and Kirstin Dähnke

Short summary
Nitrous oxide (N2O) is an important greenhouse gas. However, N2O emissions from estuaries underlie significant uncertainties due to limited data availability and high spatiotemporal variability. We found the Elbe Estuary (Germany) to be a year-round source of N2O, with the highest emissions in winter along with high nitrogen loads. However, in spring and summer, N2O emissions did not decrease alongside lower nitrogen loads because organic matter fueled in situ N2O production along the estuary.
