A timely boost to research on carbon sequestration
Article Abstract:
The US Dept of Energy has announced the creation of two centres to investigate ocean and terrestrial sequestration methods. It is also calling for proposals for research into the separation and capture of carbon dioxide from the atmosphere. It will be necessary for a lot more basic research to be undertaken, especially in the oceans, in order for significant sequestration to be feasible. However, mixed views are being expressed about plans at the Pacific International Center for High Technology Research to inject liquefied carbon dioxide at around 900 mt off the Kona coast.

Nitrogen deposition makes a minor contribution to carbon sequestration in temperate forests
Article Abstract:
The global nitrogen cycle has been altered and more atmospheric N(sub2) is converted into biologically reactive forms through anthropogenic activities. Tree growth in northern temperate areas is nitrogen-limited, and thus raised nitrogen deposition could result in attenuating rising atmospheric CO2. It is uncertain whether elevated nitrogen deposition or other factors are the main cause of carbon sequestration in northern forests. (super15)N-tracer studies suggest that elevated nitrogen deposition is not likely to be a major contributor to the CO2 sink.

Effect of natural iron fertilization on carbon sequestration in the southern ocean
Article Abstract:
The report on the observations of a phytoplankton bloom induced by natural iron fertilization-an approach that offers opportunity to overcome some of the limitations of short-term experiments is presented. It is found that a large phytoplankton bloom over the Kerguelen plateau in the Southern Ocean sustained by supply of iron and major nutrients to surface waters from iron-rich deep water below.
