Throughout most of a core the fractional ionization depends on the fractional elemental abundances of sulfur and metals such as Na and Mg.
abundances of the isotopes of each element characteristic only for the earth?
copepod abundances thus occurred repeatedly and across a wide range of scales.
There was also a generally good agreement between the abundances of the rarer large biomass dominant calanoid copepods estimated by both samplers.
elemental abundances and instrumental spectral resolution and then calculate and plot the spectrum.
