A stable isotope technique for measuring production and consumption rates of nitrous oxide in coastal waters

S Punshon, RM Moore - Marine chemistry, 2004 - Elsevier
The coastal ocean is a globally important source of atmospheric nitrous oxide (N2O), yet
understanding the behaviour of N2O in the near-shore water column is often hampered by …
