Iron Fertilisation Experiments in the Southern Ocean

Oceans play a key role in shaping global climate by regulating atmospheric concentrations of CO2. However, fossil fuel burning has swamped the natural carbon cycle and it is a challenge for earth system scientists to investigate how ocean uptake can be enhanced by manipulating natural processes responsible for sequestering CO2 from the atmosphere. One such technique, ocean iron fertilisation (OIF), involves fertilising certain ocean regions with trace amounts of iron to stimulate the growth of microscopic plant-like organisms known as...
