| Summary: | Polar Frontal Zone; EisenEx; protozooplankton; small metazooplankton; iron fertilization; vertical fluxes; grazing impact. - This thesis provides a comprehensive assessment of the response and vertical distribution of major components of the pelagic ecosystem and highlights the species interactions shaping this open ocean environment and its associated biogeochemical cycles.During the iron fertilization experiment (EisenEx), carried out in the Polar Frontal Zone of the Southern Ocean in austral spring (November), the composition, succession and temporal development of the nano-, microprotozooplankton (protozoa between 2 and 20 æm and 20 and 200 æm respectively), mesozooplankton (protozoa > 200 æm) and small metazooplankton (copepod nauplii, copepodites and adults of small species) assemblage was successfully followed for three weeks and compared with non-fertilized, surrounding water. The grazing impact of microprotozooplankton on the natural phytoplankton assemblage was also studied under controlled . @Bremen, Univ., Diss., 2004 |
