Abstract

This dataset includes nitrous oxide (N2O) concentrations and associated physicochemical parameters from the CTD sensor package collected on R/V Atlantis cruise AT15-61 in January-February 2010 and R/V Melville cruise MV1104 in March-April 2011 in the Eastern Tropical South Pacific (ETSP). These data were published as Figure 5 in Santoro et al., 2020 (doi:10.1002/essoar.10503499.1).

Cite Dataset

These data were published as Figure 5 in Santoro et al. (2020).

Nitrate (NO3-) and Nitrite (NO2-) d15N and d18O data from the samples are available in the related dataset "ETSP NO3 and NO2 isotopes" (https://www.bco-dmo.org/dataset/903891).

Description of changes/updates contained in version 2 of this dataset:
Most depths were analyzed in duplicates from two bottles (i.e. one measurement of all isotopic variables and a concentration per bottle). This version (v2) contains each measurement in a unique column (i.e. d15n_alpha1, d15n_alpha2, etc.). A quality control (QC) flag was also added for each measurement using the SeaDataNet QC guidelines available at https://www.seadatanet.org/Standards/Data-Quality-Control.
