Concept
Enrichment of nitrogen-15 in nitrate {15N in NO3- CAS 14390-96-6} {delta(15)N} in the water body [dissolved plus reactive particulate <0.4/0.45um phase] by filtration, denitrification to N2O by cultured bacteria and Continuous-Flow Isotope Ratio Mass-Spectrometry

| Definition | The isotopic enrichment (1000*(sample(15N/14N ratio) - natural ratio)/(natural ratio)) of nitrogen 15 in nitrate molecules (NO3-) in a body of salt or fresh water after removal of particles larger than 0.4/0.45 microns by filtration. | ||
