LOHAFEX: An Indo-German iron fertilization experiment
Date:1/13/2009

toplankton blooms of similar size and composition to natural blooms fertilized by iron in settling dust and from melting icebergs. However, in contrast to the remote oceanic regions previously fertilized, LOHAFEX will be located in a more productive region of the Southern Ocean inhabited by coastal species of phytoplankton. They grow faster and are more palatable to the zooplankton, including the shrimp-like krill, than their spiny open-ocean counterparts. Krill is the main food of Antarctic penguins, seals and whales but their stocks have declined by over 80% during the past decades, so their response to the iron-fertilized bloom (if they are present in the experimental area) will indicate whether the alarming decline is due to declining productivity of the region, for which there is evidence. The LOHAFEX patch will have a similar impact on the ecosystem as melting icebergs and is large enough to counteract the effects of dilution due to spreading over 45 days of the experiment.

Spending seventy days in a notoriously stormy stretch of ocean will be a strenuous experience for the scientists and crew on board Polarstern. Smetacek reports that bad weather was encountered shortly after leaving Cape Town, so many of the scientists are still adjusting to the movements of the ship. However, he is confident that this is a temporary phase and that soon everyone will be able to prepare the laboratories for the start of the experiments.
