Iron fertilisation geoengineering affects deep sea ecology too

Ocean iron fertilisation, one of the most discussed CDR geoengineering proposals, deliberately tries to stimulate biological activity in the upper ocean. New research shows this in turn affects ecology at the ocean floor too. Let’s just hope sea cucumbers don’t … Continue reading

Antarctic krill promotes CO2 uptake by plankton through iron fertilisation

Iron is very rare in the upper layers of the world´s oceans, where photosynthesis is possible and therefore biological activity and concentration of living biomass is highest, making the mineral a growth-limiting nutrient in 40 percent of the world’s oceans, … Continue reading
