# Analysis by Hazen Research Inc, Golden Colorado
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.
##Approximately 50% of the mass of the as is inorganic sulfate ions.
An * means that a sample is no longer available, and nd means that an item was not determined.
The available standard aquatic fulvic acids, humic acids  were isolated from the same location on the Suwannee River, Georgia, U.S.A. in 1982-83, 2003, 2016 respectively.
