  • 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 ...
  • Size-fractionated major particle composition and concentrations from the US GEOTRACES North Atlantic Zonal Transect 

    Lam, Phoebe J.; Ohnemus, Daniel C.; Auro, Maureen E. (Elsevier, 2014-11-18)
    The concentration and the major phase composition (particulate organic matter, CaCO3, opal, lithogenic matter, and iron and manganese oxyhydroxides) of marine particles is thought to determine the scavenging removal of ...
