AUSTRALIA FOOD AND AGRIBUSINESS


Feeding the ocean through carbon transfer


BETWEEN 2000 AND 2007, A TOTAL OF 25 PER CENT OF ALL CARBON DIOXIDE EMISSIONS WERE REMOVED BY THE WORLD’S OCEANS INTO WHAT IS THE LARGEST CARBON SINK ON THE PLANET – THE DEEP OCEAN. CARBON SEQUESTRATION WILL PROVIDE SOME ACCELERATION OF THIS NATURAL PROCESS.


F


or the first time in human history the world is facing unparalleled shortages in resources vital to sustain a


growing human population. This rapidly emerging crisis is exasperated by climate change and in particular, extremes of temperature, rainfall and destructive climatic events. The root cause of the crisis lies in man’s impact on the environment, our demand for energy and our thirst for water resources. Global food security is now at risk.


Efforts to increase food production on land will be severely constrained by the rising cost of oil and the impacts of climate change (e.g. prolonged periods of drought, wildfire and soil erosion). Carbon dioxide (CO2


contributes to global warming, while CO2


in the deep ocean does not. The


carbon store in the deep ocean is 50 times larger than that of the atmosphere, so the percentage change in the size of the deep ocean sink will be 50 times less than for the atmosphere. The waste product of using fossil fuel is, at present, dumped in the atmosphere where it is contributing to climate change. With Ocean Nourishment™, the CO2


is converted to


biological material, with some eventually creating high quality protein, while the larger fraction is added to the natural stores of carbon in the deep ocean. An established Ocean Nourishment site in full operation would sequester 5–8 MT


68 of CO2 per annum and lead to an increase


in fisheries of some 300,000 tonnes (wet weight) per annum. The Ocean Nourishment Corporation


was founded in 2004 and operates globally from headquarters in Sydney, Australia. ONC has taken the lead to explore, develop and demonstrate that our food catch from the world’s oceans can be increased, reversing the current decline in sustainable marine harvest. ONC’s vision is to demonstrate how

a relatively simple process, implemented in a sophisticated and scalable manner, could provide significant improvements in respect to three current global problems: food security, climate change and ocean acidification. ONC is now seeking to align strategic


partners, infrastructure investors and technical collaborators to this vision.


The technology Ocean Nourishment is a licensed process providing missing macronutrients to the open ocean in order to enhance biological productivity (marine plant growth) and hence sequester carbon and grow food. The additional nutrient stimulates further growth of existing marine plants at the base of the marine food chain, and their


increased growth both absorbs CO2 from the atmosphere and stimulates the marine food web. This process of increasing ocean productivity replicates
