<div><p>Seawater samples between 65 S and 20 S were collected by the science crew of the CLIVAR program (CLIVAR P16S during January/February 2005). Seawater samples between 8 S and 7N were collected by the science crew of NOAA ship R/V Ka’imimoana. Nutrients were measured on board (nitrate, nitrite, phosphate, and silicate), and 50 mL samples were frozen. Samples from the Chilean Margin were acquired in February 2010 and frozen, and nutrient measurements were made at Rutgers University shortly afterward.</p></div>
Nitrate and Oxygen isotope measurements from CLIVAR line P16S in 2005
<div><p>Nitrogen and Oxygen isotopes in Nitrate (NO3) measurements from samples retrieved from CLIVAR P16S in 2005.</p>
<p>These data are discussed in <strong>Rafter et al., 2013</strong>. Coupled nitrate nitrogen and oxygen isotopes and organic matter remineralization in the Southern and Pacific Oceans,<em> J. Geophys. Res. Oceans</em>, <strong>118</strong>, 4781-4794, doi: 10.1002/jgrc.20316.</p></div>
South Pacific Nitrate Isotopes
<div><p>All samples were analyzed at Princeton University for nitrate N and O isotopes using the "denitrifier" method [Sigman et al., 2001; Casciotti et al., 2002]. In this method, nitrate and nitrite are converted to N2O gas using denitrifying bacteria and the N and O isotopes of this N2O are measured on an isotope ratio mass spectrometer. These measurements are referenced to atmospheric N2 or Vienna Standard Mean Ocean Water, respectively, with analytical precision of +/-0.2% for nitrate d15N and +/-0.3% for nitrate d18O for in-house seawater-based reference material. The reported measurements are of nitrate + nitrite. Nitrite is generally less than 1% or less of the nitrate + nitrite at all stations and for simplicity the analyses are referred to below as "nitrate."</p></div>
