Sowing seeds uncertain: Ocean iron fertilization, climate change, and the...
In a world plagued by the effects of climate change, ocean iron fertilization and other geoengineering techniques1 could help to respond and adapt to this global environmental crisis.
View ArticleWhat drives the increased phytoplankton biomass in the Arabian Sea?
The seasonal variability of phytoplankton biomass in the Arabian Sea, though a well researched topic, its inter-annual variability is less explored and understood. Analysis of the satellite-derived...
View ArticleIron-rich dust fuelled 4 million years of ice ages
Dust is all that's needed to plunge the world into an ice age. When blown into the sea, the iron it contains can fertilise plankton growth on a scale large enough to cause global temperatures to drop.
View ArticleChanging basic nature
Countries move from labs to seas to study the implications of ocean acidification. On a pleasant morning when fifty-four-year-old Australian marine diver David Hannan was gearing to plunge into the deep
View ArticleDeep carbon export from a Southern Ocean iron-fertilized diatom bloom
Fertilization of the ocean by adding iron compounds has induced diatom-dominated phytoplankton blooms accompanied by considerable carbon dioxide drawdown in the ocean surface layer. However, because the
View ArticleThe great iron dump
The discovery that marine algal blooms deposit organic carbon to the deep ocean answers some — but not all — of the questions about whether fertilizing such blooms is a viable strategy for mitigating...
View ArticleGeoengineering in relation to the Convention on Biological Diversity:...
The Conference of the Parties (COP) of the Convention on Biological Diversity (CBD) first turned its attention to geoengineering at its ninth meeting in 2008, in the context of ocean fertilization. The

Carbon dioxide removal (CDR) approaches are efforts to reduce the atmospheric CO2 concentration. Here we use a marine carbon cycle model to investigate the effects of one CDR technique: the open ocean
View ArticleCovariation of deep Southern Ocean oxygenation and atmospheric CO2 through...
A reconstruction of changes in ocean oxygenation throughout the last glacial cycle shows that respired carbon was removed from the deep Southern Ocean during deglaciation and Antarctic warm events,...

Power stations, ships and air traffic are among the most potent greenhouse gas emitters and are primarily responsible for global warming. Iron salt aerosols (ISAs), composed partly of iron and chloride,
