Nitrate + nitrite isotope measurements from surface and water-column profiles in the Atlantic Sector of the Southern Ocean during the SCALE 2019 cruise aboard the S.A. Agulhas II from Oct 2019 to Nov 2019

Here we present nitrate + nitrite (NO3– + NO2–) isotopic compositions (δ15N and δ18O) from Southern oCean Seasonal Experiment (SCALE) research cruise onboard the S.A. Agulhas II. This cruise sampled surface and water-column profiles of the late spring/early summer Atlantic Sector of the Southern Ocean, starting and ending in Cape Town, South Africa along the Good Hope line to the ice edge, from October 2019 to November 2019. These data focused on potential drivers of the nitrate plus nitrite isotope effect.
