Introduction

This auxiliary material contains one figure and two tables.

Figure S1. Correlation between 13C-DIC, and 14C-DIC in ambient groundwater in 2002 and 2003 at Glaciofluvial (plus signs, GF-1) and alluvial (diamonds, AL-1) sites.

2. 2007jg000482-ts01.txt
Table S1. Cation concentrations (mg L-1), temperature (deg C), and specific conductance (uS) in ambient groundwater in August-Sept 2003 at Glaciofluvial (GF) and Alluvial (AL) riparian zones.  Values are means from multiple wells at each site-depth.
