<p>We propose to synthesize large-scale oceanic (dissolved oxygen, dissolved inorganic carbon, sea-surface temperature, mixed layer depth, heat flux) and atmospheric (O₂/N₂ ratio) datasets at on large scales in the Southern Hemisphere south of 30 S.&nbsp; The chemical and physical datasets will be used to construct estimates of monthly, zonally-averag ed net community production of organic carbon in the ocean mixed layer.&nbsp; Following these analyses, we will also investigate interannual relationships between those variables (O₂/N₂, SST, heat flux) which are available as continuous time-series with the goal of understanding interannual controls on production and carbon cycling.&nbsp; Our study will clarify the magnitude of and large-scale controls on production and carbon flux in the Southern Ocean and provide a basis for intercomparison with independent estimates based on satellite-derived ocean color.&nbsp; These studies will also establish the basis for using atmospheric observations for documenting and interpreting annual and interannual variations in the future.</p>
