Historically, the oceans have done much of the planet's heavy lifting when it comes to sequestering carbon dioxide from the atmosphere. Microscopic organisms known collectively as phytoplankton, which grow throughout the ...

(Phys.org) —An international team of researchers has found evidence in drill core samples taken near Antarctica that adds credence to the iron fertilization hypothesis. In their paper published in the journal Science, the ...
Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or - a surprising new study finds - float up from the sea floor. The discovery, published online ...

Removal of excess carbon dioxide in the atmosphere, in addition to major reductions in ongoing emissions, is required to stave off the most severe consequences of climate change. Large-scale ocean iron fertilization is one ...

Changes in the concentration of atmospheric carbon dioxide (CO2) are considered to be the main cause of past and future climate change. A long-standing debate centers on whether the roughly 30 percent lower CO2 content of ...

Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of the ocean's ...

Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting ...
