DESCRIPTION:The Southern Ocean is an important regulator of the climate sy
 stem\, particularly in buffering atmospheric carbon dioxide (CO2) concentr
 ations. Regions of high productivity associated with melting sea ice and d
 ownstream of islands establish the Scotia Sea as sustaining one of the mos
 t active biological carbon pumps. \n\nSeasonal deficits in inorganic carbo
 n during summer ice melt indicate that carbonate mineral precipitation had
  taken place in the sea ice. Combined with biological carbon uptake\, this
  "sea ice carbon pump" created a sink for atmospheric CO2 at the ice edge.
  Extensive diatom blooms downstream of South Georgia created an intense su
 mmertime sink for atmospheric CO2\, the strongest biological carbon uptake
  in ice-free waters of the Southern Ocean to date. \n\nThe Scotia Sea is a
  mosaic of archetypal Southern Ocean environments and provides a natural m
 esocosm to investigate the processes that affect the marine carbon cycle o
 f the contemporary and future Southern Ocean.
