Science status 1

• The Malvinas Current is thought to be a major
  nutrient source for maintaining the productivity
  of the Patagonia shelf break. 
• Recent findings suggest that the current is
  organized as several alongshore fronts and jets,
  which at times may extend inshore, fertilizing
  the mid-shelf region. 
• An unusually large inshore excursion may have
  triggered the extraordinary phytoplankton bloom
  observed in austral spring 2003.

• The Malvinas and Brazil Currents have a profound
  impact on the along shelf transport in the
  middle and outer shelf.
• The Malvinas Current impacts the Southern
  Brazilian Shelf and the Brazil Current
  interactions with the bottom topography induces
  shelf-break upwelling.

Science status 3

• The Patagonia shelf absorbs large amounts of CO2
  from the atmosphere, at rates only comparable
  with the northern North Atlantic.
• The uptake occurs primarily over frontal regions
  where phytoplankton blooms are largest, with
  peaks during austral spring and summer.
