Abstract

This dataset includes vertical profiles of N2 gas concentrations in excess of equilibrium values along with the isotopic composition of total N2, NO3- and NO2- from R/V New Horizon cruise NH1410 in the Eastern Tropical North Pacific from May to June 2014.

Vertical profiles from the Mexican OMZ of N2 gas concentrations in excess of equilibrium values along with the isotopic composition of total N2, NO3- and NO2-.
