Investigators typically measure the 15N2 atom% of the 15N2-enriched inoculum by MIMS, and extrapolate the 15N2 atom% in the incubations based on the inoculum value. Here, we demonstrate that such extrapolation yields inaccurate estimates of the 15N2 atom% of incubations. The latter should be measured directly.\n\ncdm_data_type = Other\nVARIABLES:\nSample (unitless)\nBaro_Press (unknown)\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)\nmeas_at_pcnt (unitless)\navg_measured_a_pcnt (unitless)\n https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_778126_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_778126/index.htmlTable https://www.bco-dmo.org/dataset/778126 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_778126.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_778126&showErrors=false&email= BCO-DMO bcodmo_dataset_778126
