Air-Sea O2 Flux - monthly anomalies from Southern Ocean seasonal net production from atmospheric and ocean data sets, 2002 (U.S. JGOFS Synthesis & Modeling Phase project results)

<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>
