Elemental Compositions and Stable Isotopic Ratios of IHSS Samples

 

Cat. No. H2O Ash C H O N S P δ13C δ15N

H2O content is the %(w/w) of H2O in the air-equilibrated sample (a function of relative humidity).
Ash is the %(w/w) of inorganic residue in a dry sample.
C, H, O, N, S, and P are the elemental composition in %(w/w) of a dry, ash-free sample.
δ13C and δ15N are the abundances of the respective stable isotopes in units of per mil, or o/oo.
The data for bulk source materials are reported on an as-stored basis, except that %H and %O are corrected for water content.
An * means that a sample is no longer available, and nd means that an item was not determined.
The two available standard aquatic fulvic acids, 1S101F and 2S101F, were isolated from the same location on the Suwannee River, Georgia, U.S.A. in 1982-83 and 2003, respectively.
