Nitrate isotopes of seawater from Surprise Island in New Caledonia (2017 and 2023)

DOI

This dataset presents data of Nitrate plus nitrite δ15N (vs. AIR) and nitrate puls nitrite concentration measurements along a reef transect (2017 and 2023) on the reef flat of Surprise Island in the D'entrecasteaux Reefs, and also a reference site on the atoll rim. Nitrate isotope measurements have been performed using the denitrifier method (Weigand et al., 2016; doi:10.1002/rcm.7570) on seawater and groundwater samples from the CACAO expedition (2023; doi.org/10.17600/18002518) and TARA ENTRECASTEAUX 2017. The seawater along the reefflat and groundwater samples are exposed to seabird-derived nutrients (Choisnard et al. 2024, doi:10.1029/2024JC021004).
