Plankton Compositions and Trace Element Fluxes from the Surface Ocean

摘要: Plankton samples have been carefully collected from a variety of marine environments under the rigorous conditions necessary to prevent contamination for major and trace-chemical analysis. Immediately after collection, were subjected series physical chemical leaching — decomposition experiments designed identify trace element composition particulate carrier phases. Elements examined through some or all these include: C, N, P, Ca, Si, Fe, Mn, Ni, Cu, Cd, Al, Ba Zn. Emphasis was placed on identification element/major ratios in biogenic materials.
