Hi all - Many thanks to Scott, Ana, Aaron, Stacey, Amanda, LaRoy, Julie, Alea, and Dan for the helpful and varied responses to my inquiry. Here is a summary of references, resources, and responses along this thread:

I would also refer you to work by Rose Cory, Diane McKnight, Rudolf Jaffé, Rasmus Bro, and Colin Stedmon. Also look at work by George Aiken from USGS, who has many publications on trace element-DOM chemistry. Vegas-Vilarrúbia , T., J.E. Paolini, and J.G. Miragaya. 1988.

If you are interested in the "tannic" dissolved organic matter, one method to look into might be excitation-emission matrix (EEM) fluorescence spectroscopy with parallel factor analysis (PARAFAC).

Estimable Ecologgers - Does anyone have any references on chemical characterization of tannic / blackwater streams? What are key chemical parameters that distinguish such streams? Dissolved organic carbon? pH? Alkali and alkaline earth metal cations? Something else? Some combination of these players? Are there different "kinds" of tannic streams? Visually, it's easy enough to see a stream looks like tea, but is there a suite of chemical parameters that correspond to this visual perception? Much obliged - Brian Brian A.
