  • Does a ballast effect occur in the surface ocean? 

    Sanders, Richard J.; Morris, Paul J.; Poulton, Alex J.; Stinchcombe, Mark C.; Charalampopoulou, Anastasia; Lucas, Mike I.; Thomalla, Sandy J. (American Geophysical Union, 2010-04-29)
    The oceanic biological carbon pump (BCP), a large (10 GT C yr−1) component of the global carbon cycle, is dominated by the sinking (export) of particulate organic carbon (POC) from surface waters. In the deep ocean, strong ...
  • High biomass, low export regimes in the Southern Ocean 

    Lam, Phoebe J.; Bishop, James K. B. (2006-06-28)
    This paper investigates ballasting and remineralization controls of carbon sedimentation in the twilight zone (100-1000 m) of the Southern Ocean. Size-fractionated (<1 μm, 1-51 μm, >51 μm) suspended particulate matter ...
  • Opal (Zn/Si) ratios as a nearshore geochemical proxy in coastal Antarctica 

    Hendry, Katharine R.; Rickaby, Rosalind E. M. (American Geophysical Union, 2008-06-18)
    During the last 50 years, the Antarctic Peninsula has experienced rapid warming with associated retreat of 87% of marine and tidewater glacier fronts. Accelerated glacial retreat and iceberg calving may have a significant ...
