| Zusammenfassung |
| Rising atmospheric CO2 is acidifying the surface ocean, a process which
is expected to greatly influence the chemistry and biology of the future
ocean. Following the development of iron-replete phytoplankton blooms in a
coastal mesocosm experiment at 350, 700, and 1050 μatm pCO2, we
observed significant increases in dissolved iron concentrations, Fe(II)
concentrations, and Fe(II) half-life times during and after the peak of
blooms in response to CO2 enrichment and concomitant lowering of pH,
suggesting increased iron bioavailability. If applicable to the open ocean
this may provide a negative feedback mechanism to the rising atmospheric
CO2 by stimulating marine primary production. |
