New codes needed for N2O production and consumption rates (BODCNVS-808)

[gwemon]

In relation to protocol https://www.frontiersin.org/articles/10.3389/fmars.2021.611937/full the following 2 new codes are needed:

N2OPR = The production of nitrous oxide [N2O CAS 10024- 97-2] per day per unit volume of the water body by 15N [15N CAS 13767-16-3, CAS 68378-96-1, CAS 31432-46-9] isotope labeled tracer addition, incubation and purge- and trap measurement at the GC-IRMS.

N2OCON = The consumption of nitrous oxide [N2O CAS 10024-97-2] per day per unit volume of the water body by 15N [15N CAS 10024-97-2] isotope labeled tracer addition, incubation and purge- and trap measurement at the GC-IRMS.

N2OPR will be modelled as follows:
Property= Production rate
Object of Interest= Nitrous Oxide
Matrix= water body [dissolved plus reactive particulate]
measurement to matrix relationship= per day per unit volume of the
sample preparation method= 15N-tracer addition, incubation
analytical method= gas chromatography-isotope ratio mass spectrometry with purge trap system

N2OCON will be modelled as follows:
Property= Consumption rate
Object of Interest= Nitrous Oxide
Matrix= water body [dissolved plus reactive particulate]
measurement to matrix relationship= per day per unit volume of the
sample preparation method= 15N-tracer addition, incubation
analytical method= gas chromatography-isotope ratio mass spectrometry with purge trap system

The following codes have been created and queued for publication on the NVS:
N2OCON01 Consumption rate of nitrous oxide {N2O CAS 10024-97-2} per day per unit volume of the water body [dissolved plus reactive particulate phase] by 15N-tracer addition, incubation, fixation, gas purging and trapping and gas chromatography-isotope ratio mass spectrometry
N2OPRD01 Production rate of nitrous oxide {N2O CAS 10024-97-2} per day per unit volume of the water body [dissolved plus reactive particulate phase] by 15N-tracer addition, incubation, fixation, gas purging and trapping and gas chromatography-isotope ratio mass spectrometry
