LOHAFEX
From Wikipedia, the free encyclopedia
LOHAFEX was an ocean iron fertilization experiment jointly planned by the Council of Scientific and Industrial Research (CSIR) in India and the Helmholtz Association in Germany. The purpose of the experiment was to see if the iron would cause an algal bloom and trap carbon dioxide from the atmosphere. While an algal bloom did result, it was smaller than expected and as most of the algae were consumed by zooplankton instead of sinking to the ocean floor, the amount of carbon dioxide permanently removed from the atmosphere was deemed negligible. The result was thus a setback for plans to use iron fertilization of the oceans to create negative carbon dioxide emissions.
