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 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_778000.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_778000&showErrors=false&email= BCO-DMO bcodmo_dataset_778000

Rising carbon dioxide emissions and anthropogenic nutrient input are expected to increase these pCO2 and DO cycles in severity and duration of acidification and hypoxia. How coastal marine organisms respond to natural pCO2 \\u00d7 DO variability and future climate change remains largely unknown. Here, we assess the impact of static and cycling pCO2 \\u00d7 DO conditions of various magnitudes and frequencies on early life survival and growth of an important coastal forage fish, Menidia menidia. Static low DO conditions severely decreased embryo survival, larval survival, time to 50% hatch, size at hatch and post-larval growth rates. Static elevated pCO2 did not affect most response traits, however, a synergistic negative effect did occur on embryo survival under hypoxic conditions (3.0 mg L-1). Cycling pCO2 \\u00d7 DO, however, reduced these negative effects of static conditions on all response traits with the magnitude of fluctuations influencing the extent of this reduction. This indicates that fluctuations in pCO2 and DO may benefit coastal organisms by providing periodic physiological refuge from stressful conditions, which could promote species adaptability to climate change.\n\ncdm_data_type = Other\nVARIABLES:\nExperiment (unitless)\nExperiment_descrip (unitless)\nTreatment (unitless)\nCycling_Pattern (unitless)\nMetric (unitless)\nMeasured_pH (Measured P H, pH scale, NIST)\nMeasured_pH_SD (Measured P H SD, pH scale, NIST)\nMeasured_DO (milligrams per liter (mg L-1))\nMeasured_DO_SD (milligrams per liter (mg L-1))\npCO2 (P CO2, microatmospheres (uatm))\npCO2_SD (P CO2 SD, microatmospheres (uatm))\nAT (micromoles per kilogram (umol kg-1))\nAT_SD (micromoles per kilogram (umol kg-1))\n...

Mussels (M. trossulus) were collected in May 2012 from Argyle Creek, San Juan Island, WA (48.52\\u02da N, 123.01\\u02da W) and held in a mesh box submerged under the dock at Friday Harbor Laboratories (FHL), San Juan Island, WA for up to 14 d.

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.
