If you produce food and carbon sinks with your ocean fertilization experiment is it no longer geoengineering? Or is it mitigation, adaptation, and geoengineering all in one?
Project Aims to Find Carbon Sinks in Aquaculture
25 June 2013SPAIN - Researchers in Spain are finding ways to use aquaculture to create carbon sinks. This is hoped to help prevent climate change.
This initiative, developed by the OESA Foundation in collaboration with the Biodiversity Foundation of the Ministry of Agriculture, Food and Environment, University of Santiago de Compostela and the company Algaenergy, attempt to explore how aquaculture can help mitigate the effects of climate change through the cultivation of fixing carbon dioxide (CO2) in algae and molluscs (mussels, oysters and clams).
The project aims to find new carbon sinks in Spanish aquaculture production, of which over 80 per cent is molluscs.
Among the objectives of the project is to equip the Spanish aquaculture sector with new tools to calculate the carbon footprint of the cultivated species.
During the first half of the year, progress was made in developing a first report on the interactions of climate change and aquaculture.

Another thing to bear in mind is that by draining wetlands we have
greatly reduced the flow of iron into the oceans. This is because peat
produces complex organic acids (eg, humic acid) which dissolve and
chelate iron - abundant in many rocks - and carry it down to the ocean.
So we have already "experimented" inadvertently by reducing iron inputs
to the ocean. And of course this is the most useful form of iron as it
is in a highly soluble and bio-available form. And we have replaced that
iron with masses of silt, nitrate and phosphate from stupid kinds of
agriculture.
