On the processes controlling the seasonal cycles of the air–sea fluxes of O<sub>2</sub> and N<sub>2</sub>O: A modelling study

Abstract: A B S T R A C TThe seasonal dynamics of the airÁsea gas flux of oxygen (O 2 ) are controlled by multiple processes occurring simultaneously. Previous studies showed how to separate the thermal component from the total O 2 flux to quantify the residual oxygen flux due to biological processes. However, this biological signal includes the effect of both net euphotic zone production (NEZP) and subsurface water ventilation. To help understand and separate these two components, we use a large-scale ocean general cir… Show more

“…Modeling studies that have assessed this relationship between oxygen and heat fluxes have found that the magnitude of the calculated thermal oxygen flux can be overestimated due to the assumption of instantaneous oxygen equilibration (Jin et al, ). Additionally, the thermally driven oxygen fluxes may lag the heat flux by a few weeks (Manizza et al, ). However, these results are dependent on the air‐sea flux parameterization and ocean model used and it is unclear if the relationship would be different with the modified Liang et al () parameterization used in this study.…”

“…The standard MITgcm fully represents the marine O 2 cycle and was expanded by Manizza et al . [] to include a marine cycle of N 2 O, Ar, and some “ad hoc” O 2 ‐like tracers. The latter allow the separation of processes affecting the seasonal cycle of oceanic O 2 , including thermal solubility, NCP, and physical ventilation.…”

“…The Saikawa et al prior fluxes included a combination of inventory‐based industrial and agricultural soil emissions from EDGAR v4.1, biomass burning emissions from Global Fire Emissions Database v3, model‐based natural soil emissions (Saikawa et al, ), and model‐based oceanic emissions Manizzap et al (). All of the input fluxes had monthly resolution, except for the EDGAR emissions, which had annual resolution (EDGAR, ).…”
