From: N2O dynamics in the western Arctic Ocean during the summer of 2017
Vertical distribution of N2O measured in the WAO water column during the summer of 2017 with saturation levels (N2Osat (%) = (N2Omeasured/N2Oeq) \(\times\) 100; blue to red gradient color bar). Based on the vertical composition of water masses in the study area (surface, Pacific summer water and fresh water; intermediate, Pacific Winter Water; and deep areas, Atlantic Water and Arctic Bottom Water), we represent the vertical N2O distribution by dividing into three layers (i.e., surface, 0–50 m; intermediate, 50–200 m; and deep layer, 200–2200 m). To show contrasting values associated with saturation levels (%), the surface layer is shown separately for SC and NC. To investigate the potential sources of biogeochemically derived N2O (ΔN2O) production, the figures on the right-hand side show the correlations of ΔN2O with DIN and N* in the surface layer of the SC (green color boxes), and with AOU and N* in the intermediate layer (orange color boxes), including statistical information (R2 and p values). The inset shows the correlation between ΔN2O and DIN in the intermediate layer. Note that this figure was generated using MATLAB program (ver. R2019b and www.mathworks.com).
