The Alfred Wegener Institute for Polar and Marine Research (AWI) from Germany gave a plenary presentation about the LOHAFEX ocean iron fertilization experiment (OIF) which was conducted in cooperation with the Indian National Oceanographic Institute (NIO). LOHAFEX was carried out from 7 January to 17 March 2009 in an ocean eddy at 48°S 16°W. Preliminary results indicate that most of the phytoplankton was top-down controlled by grazing zooplankton, that in turn were predated on by amphipods. In conclusion the CO2 drawdown effect of the OIF was low. Outline, concept, approach, detailed results and the preliminary conclusions are available from the pdf.attachment to the minutes of the meeting.
