The Role of Diatom Production and Si Flux and Burial in the Regulation of Global Cycles

Global Biogeochemical Cycles, vol. 20, no. 4, 2006

The present GBC special section arose from an American Geophysical Union Chapman Conference held 22–26 September 2003 on the Greek Island of Paros. Studies of the cycling of the major nutrients (N, P, Si) are an essential step toward assessing the role of biogeochemical processes in global change through, for example CO2 uptake and draw down.
