[Depth profiles of N2O concentrations and site preference KM1314] - Depth profiles of N2O concentrations and site preference from R/V Kilo Moana KM1314 in the The North Pacific Ocean (Seattle to Honolulu, including Line P, Station ALOHA), Aug - Sept 2013 (Significance of nitrification in shaping planktonic biodiversity in the ocean)

However, in situ measurements of N2O concentrations in the northeastern Pacific Ocean are scarce, and the processes controlling its production and consumption remain poorly constrained. During the R/V Kilo Moana cruise KM1314 (August 2013), vertical profiles were collected at Stations 1, 5, 8, and 13 from the surface to 300 m depth.

The dataset includes dissolved N2O concentrations and isotopic measurements, including site preference and related isotope parameters. These observations provide constraints on the pathways and dynamics of N2O cycling in the upper water column and support investigation of nitrification and other microbial processes regulating marine N2O production in this region.
