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/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

The survey includes environmental observations, physico-chemical data, chlorophyll, total and dissolved nutrients. The Lake Erie Center for Fresh Waters and Human Health is a five-year, multi-institutional effort aimed at understanding the environmental factors and ongoing changes that influence the growth and toxicity of cyanobacterial harmful algal blooms (cHABs) in Lake Erie.\n\ncdm_data_type = Other\nVARIABLES:\nStation (unitless)\nDeployment (unitless)\nAlt_Station (unitless)\nLake (unitless)\nDate (unitless)\nTime_EST (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (Long, degrees_east)\nWater_Depth (meters (m))\nIce_Cover (percent (%))\nSnow_Cover (percent (%))\nIce_Type (unitless)\nIce_Thickness (inches (in))\nAir_Temp (Degrees Celsius)\nWater_Temp (Degrees Celsius)\nDO (microgram per liter (µg L-1))\nDO_percent (percent (%))\nCond (microsiemens per centimeter (uS/cm))\npH (unitless (pH scale))\nSechhi (meters (m))\nBaro_Press (Hg)\n...
