GWB resources and support

You can take advantage of a range of resources as you work with the GWB package:

Essentials manualUser's Guides
A set of six comprehensive GWB manuals shows you how to use the software to perform a broad range of geochemical calculations, and serves as a reference for GWB users. Order a hardcopy doc set (including the GBRM text from Cambridge) or download the manuals in pdf form. Download the cover art, too, and you can have your local copy shop print and bind the User's Guides.

GBRM textReaction modeling text
The textbook Geochemical and Biogeochemical Reaction Modeling, published by Cambridge University Press, contains a complete description of the theoretical basis of the GWB calculations as well as a large number of fully worked examples. You can download a Kindle version of the text, or purchase it in hard or soft cover.

Got wine, beer, canned beans, and a copy of Bethke's Geochemical and Biogeochemical Reaction Modeling.
