HIGHLIGHTS
- who: Biogeosciences and colleagues from the School of Geosciences, University of Edinburgh, Edinburgh, UK have published the paper: Permafrost degradation and nitrogen cycling in Arctic rivers: insights from stable nitrogen isotope studies, in the Journal: (JOURNAL) of 25/07/2022
- what: The authors show evidence for permafrost-derived DON being recycled to nitrate as it passes through the river transferring the high 15 N signature to nitrate. The study demonstrates that nitrogen inputs from permafrost thaw can be identified through nitrogen isotopes but only on small spatial scales. The authors evaluate the seasonal trend further . . .
