CO2 in springs is hard to measure

The karst research team got a visit from Hank Edenborn of DOEs NETL lab and Dorothy Vesper from WVU to learn about their CO2 sampling and logging techniques.  The loggers are very expensive and not easy to calibrate based on Hank’s experience.  Dorothy does analysis in the field, but the equipment is also expensive.  Bucknell undergrad Josh Barna has been checking stability of samples collected in our springs and they seem to be relatively stable due to the high alkalinities.  We may be able to get accurate enough CO2 data for his study of CO2 hysteresis.  Look for his poster at GSA 2016!
