Progressive decoupling between phytoplankton growth and microzooplankton grazing during an iron-induced phytoplankton bloom in the Southern Ocean (EIFEX)
Dilution experiments were performed to quantify growth and mortality rates of phytoplankton groups (as defined by pigment markers) for 5 wk in an iron-induced phytoplankton bloom during the European Iron Fertilization Experiment (EIFEX) conducted in the Southern Ocean. Rates could be reliably measured for the 2 main groups, diatoms and prymnesiophytes. Mean phytoplankton intrinsic growth rates ...
متن کاملStable Composition of the Nano- and Picoplankton Community during the Ocean Iron Fertilization Experiment LOHAFEX
The iron fertilization experiment LOHAFEX was conducted in a cold-core eddy in the Southern Atlantic Ocean during austral summer. Within a few days after fertilization, a phytoplankton bloom developed dominated by nano- and picoplankton groups. Unlike previously reported for other iron fertilization experiments, a diatom bloom was prevented by iron and silicate co-limitation. We used 18S rRNA g...

متن کاملThe Southern Ocean Iron RElease Experiment (SOIREE)* introduction and summary
This volume is dedicated to the Southern Ocean Iron RElease Experiment (SOIREE), the "rst in situ iron fertilisation experiment performed in the polar waters of the Southern Ocean. SOIREEwas an interdisciplinary study involving participants from six countries, and took place in February 1999 south of the Polar Front in the Australasian-Paci"c sector of the Southern Ocean. Approximately 3800kg o...
متن کاملThe effects of dilution and mixed layer depth on deliberate ocean iron fertilization: 1-D simulations of the southern ocean iron experiment (SOFeX)
To better understand the role of iron in driving marine ecosystems, the Southern Ocean Iron Experiment (SOFeX) fertilized two surface water patches with iron north and south of the Antarctic Polar Front Zone (APFZ). Using 1-D coupled biological–physical simulations, we examine the biogeochemical dynamics that occurred both inside and outside of the fertilized patches during and shortly after th...
