Nitrogen fixation in the Indian Ocean

Dinitrogen (N2) fixation rates measured in the Indian Ocean, collected from previously published papers. The dataset contains 241 volumetric rates (units nmol N l-1 d-1), 89 depth-integrated rates (units µmol N l-1 d-1) and metadata (including temperature, salinity, inorganic nutrient and chlorophyll concentrations) when available in the original publications.
