These measurements were used to address the source of nitrate+nitrite in surface waters observed after the 2018 Kilauea eruption entered the ocean, leading to enhanced surface ocean chlorophyll. The results are consistent with an upwelling source of nitrate+nitrite from ~400 m driven by hot lava entering the ocean, leading to increased buoyancy of waters, driving \\roils\\ (see F. J. Sansone, and J. A. Resing, 1995, J. Geophys. Res. Oceans). These data are also used as evidence that biological nitrogen fixation did not contribute to the nitrate+nitrite observed in surface waters.\n\ncdm_data_type = Other\nVARIABLES:\nStation_Number (unitless)\nTowfish_or_CTD_profile_station (unitless)\ndepth (m)\ntime (seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nKarl_HI_NO3_NO2 (Mole Concentration Of Nitrate In Sea Water, micromolar (uM))\nKnapp_NO3_NO2_d15N (Mole Concentration Of Nitrate In Sea Water, per mil)\nKnapp_NO3_NO2_d15N_std_dev (Mole Concentration Of Nitrate In Sea Water, per mil)\nKnapp_NO3_NO2_d18O (Mole Concentration Of Nitrate In Sea Water, per mil)\nKnapp_NO3_NO2_d18O_std_dev (Mole Concentration Of Nitrate In Sea Water, per mil)\nKarl_TDN (micromolar (uM))\nKnapp_TDN_d15N (Knapp TDN D15 N, per mil)\nKnapp_TDN_d15N_std_dev (Knapp TDN D15 N Std Dev, per mil)\n https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_770818_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_770818/index.htmlTable https://www.bco-dmo.org/dataset/770818 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_770818.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_770818&showErrors=false&email= BCO-DMO bcodmo_dataset_770818

Here we quantify rates of N2 fixation as well as its contribution to export production along a zonal transect in the Western Tropical South Pacific (WTSP) Ocean using N isotope (\\u201cd15N\\u201d) budgets. Comparing measurements of water column nitrate+nitrite d15N with the d15N of sinking particulate N at a western, central, and eastern station, these d15N budgets indicate high, modest, and low rates of N2 fixation at the respective stations. The results also imply that N2 fixation supports exceptionally high, i.e., >50%, of export production at the western and central stations, which are also proximal to the largest iron sources. These geochemically-based rates of N2 fixation are equal to or greater than those previously reported in the tropical North Atlantic, indicating that the WTSP Ocean has the capacity to support globally significant rates of N2 fixation, which may compensate for N removal in the oxygen deficient zones of the eastern tropical Pacific.\n\ncdm_data_type = Other\nVARIABLES:\nDate (unitless)\nlongitude (degrees_east)\nlatitude (degrees_north)\nStation (unitless)\nCast (unitless)\ndepth (m)\nSigma_theta (Sea Water Sigma Theta, kilograms per meter cubed (kg/m3))\nNO3_NO2 (micromole (uM))\nNO3_NO2_d15N (NO3 NO2 D15 N, per mil)\nNO3_NO2_d15N_1_SD (NO3 NO2 D15 N 1 SD, per mil)\n https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_733237_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_733237/index.htmlTable https://www.bco-dmo.org/dataset/733237 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_733237.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_733237&showErrors=false&email= BCO-DMO bcodmo_dataset_733237
