Side effects

EAMO has more than one effect (methane removal) on the atmosphere.

Beneficial side effects

1. EAMO removes ozone from the troposphere.

Ozone is better known in the stratosphere, because that´s where the ozone layer was (and still is somewhat) affected in the beginning of the century. However ozone also exists in the troposphere, and here it has considerable warming power. Ozone concentration is strongly associated with methane, so depleting methane will lower ozone concentration (15). Ozone concentration is highest in polluted, industrialized areas. Since we plan to disperse ISA over subtropic oceans, ozone depletion will be minimal, because there is very little ozone in the marine boundary layer (MBL – lowest ~2.000 m) over these oceans. 

2. EAMO contributes to ocean or land fertilization.

Iron is a great fertilizer, it works on land as well as in the ocean. Fertilization causes more plants or algae (phytoplankton)  to grow, and hence more consumption of CO2. Phytoplankton again is food for krill and fish. This is why we prefer iron-poor regions of the ocean for dispersion of ISA..

Both side-effects are beneficial, in that they contribute to cooling down the planet.

Gardeners know it. Iron is an excellent fertilizer (10)

Negative side effects

EAMO has no negative side effects we are aware of. 

Some scientists have said in the past that iron can contribute to the acidification of the oceans. However this was based on trials where iron was dumped into the sea from a ship and was therefore concentrated in a single location. Planes will distribute ISA over thousands of square kilometers so no more than 0.5 mg / m2 / day on average will ever reach the ocean surface or the land. 

We plan to measure the effects of ISA during a one-year testphase which we will conduct once the first plane is operational. Before that happens we will conduct an Environmental Impact Assessment (EIA) which will weigh all consequences of EAMO. 

It goes without saying that AMR will always fulfil all local, national and international legal requirements which affect our activities.
