Bioactive trace Metal distributions and Biogeochemical controls in the Southern ocean
Metal distributions Biogeochemical controls
2015/7/15
Extensive sampling in many regions of the Southern Ocean has
demonstrated that surface water concentrations of dissolved Fe are low enough
to limit phytoplankton growth. In contrast, there is curr...
Various human activities, including
fossil fuel combustion and forest clearing, emit
about eight petagrams (or billion tons) of carbon
in the form of CO2 into the atmosphere annually.
The glob...
Enhanced viral production and infection of bacterioplankton during an iron-induced phytoplankton bloom in the Southern Ocean
Enhanced viral production iron-induced phytoplankton
2014/4/18
We followed the viral response to Fe-enrichment over 3 weeks during the second iron-enrichment experiment
(EisenEx) in the Southern Ocean. Although viral abundance increased in a rather constant way ...
Growth rates of large and small Southern Ocean diatoms in relation to availability of iron in natural seawater
Growth rates of large small Southern Ocean
2014/5/30
Blooms of large diatoms dominate the CO2
drawdown and silicon cycle of the Southern Ocean in both the past
and present. The growth of these Antarctic diatoms is limited by availability of iron (and ...
