To this end, we first ensured that the IRMS returns accurate 15N2 atom% values, by measuring the 15N2 atom% of a serial dilutions of a 15N2 gas stock in air and helium. This calibration is documented herein, showing that IRMS measurements in the experimental range were accurate, as expected\n\ncdm_data_type = Other\nVARIABLES:\ncomment (unitless)\nexpected (unitless)\nmeasured (unitless)\n | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_778000_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_778000/index.htmlTable | https://www.bco-dmo.org/dataset/778000

We detail the protocol herein, and report representative MIMS measurements of the prepared standards.\n\ncdm_data_type = Other\nVARIABLES:\nBottle_vol (mililiters (mL))\nSample (unitless)\nInjection_15N2 (Injection 15 N2, mililiters (mL))\nExpected_15N_At_pcnt (Expected 15 N At Pcnt, unitless)\nTime_of_analysis (unitless)\nm_z_28 (unitless)\nm_z_29 (unitless)\nm_z_30 (unitless)\nm_z_32 (unitless)\nm_z_40 (unitless)\nN2_Ar (unitless)\nratio_28_29 (unitless)\nratio_28_30 (unitless)\nAt_15N_pcnt (At 15 N Pcnt, unitless)\nAt_15N_pcnt_avg (At 15 N Pcnt Avg, unitless)\n | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_778021_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_778021/index.htmlTable | https://www.bco-dmo.org/dataset/778021
