Bremerhaven, January 13th 2008. The German research vessel Polarstern is currently on its way to the Southwest Atlantic Sector of the Southern Ocean. The team of 48 scientists (30 from India) on board left Cape Town on 7th January to carry out the Indo-German iron fertilization experiment LOHAFEX (LOHA is Hindi for iron, FEX stands for Fertilization EXperiment). About two weeks will be required to reach the area and carefully select a suitable location, after which a patch of 300 square kilometres will be fertilized with six tons of dissolved iron. This will lead to rapid growth of the minute, unicellular algae known as phytoplankton. These algae do not only provide the food sustaining oceanic life, but also play a key role in regulating concentrations of the greenhouse gas carbon dioxide in the atmosphere. After about 45 days of interdisciplinary research, the expedition will end in Punta Arenas, Chile on 17th March 2009. LOHAFEX will provide more basic information to further our understanding of the role of ocean ecosystems in the global carbon cycle. It will help filling the gaps of knowledge mentioned by international conventions to classify the potential role of ocean fertilization as a means of reducing carbon dioxide concentrations in the atmosphere.
The scientific experiment is in accordance with the resolution of the London Convention on the regulation of ocean fertilization from October 2008 and the Decision of the Convention on Biological Diversity on ocean fertilization from May 2008 that call for further research to enhance understanding of ocean iron fertilization. For LOHAFEX, the National Institute of Oceanography (NIO), India, and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, Germany, have evaluated possible environmental impacts showing that this experiment will not cause damage to the environment. The level to which the surface-water iron concentrations will be enhanced during this ex
