Dataset: 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

N2O samples were collected using Niskin bottles attached at CTD, through silicone tubing directly into Wheaton 160 mL glass serum bottles and overflowed twice before filling. The tubing was removed, and a 1 mL headspace was introduced into each bottle before capping with a gray butyl septum. After collection, 100 μL of saturated mercuric chloride was added to each bottle and then resealed with the gray butyl septum and an aluminum crimp seal. Samples were stored in the dark at room temperature until analysis.
