I’m into the nitrogen cycle and the little critters crawling around in the sediment.

🚨🌊🧪New paper out!
Fixed-nitrogen shapes ocean productivity. Could its removal also occur in the oxygenated water column, not just sediments?
Our new data from the St. Lawrence suggest it is possible.

New Deoxygenation Threshold for N2 and N2O Production in Coastal Waters and Sediments
Fixed-N is possibly removed in suboxic (<5 μM) microzones on suspended organic matter at bulk O2 ${\mathrm{O}}_{2}$ of 32–59 μM in the St. Lawrence Estuary Benthic and possibly water column fixed...
