Iron fertilization won't work in much of Pacific, says study

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 ...

With climate, fertilizing oceans could be zero-sum game

Scientists plumbing the depths of the central equatorial Pacific Ocean have found ancient sediments suggesting that one proposed way to mitigate climate warming—fertilizing the oceans with iron to produce more carbon-eating ...

The fate of bioavailable iron in Antarctic coastal seas

Science is exploring many options for carbon dioxide sequestration in order to mitigate the climatological impact of CO2. One of these is geoengineering: deliberate, large-scale intervention in the Earth's natural systems ...

A greener way to fertilize nursery crops

A U.S. Department of Agriculture (USDA) scientist has found a "green" alternative to a type of fertilizer additive that is believed to contribute to the accumulation of heavy metals in waterways.
