Real time measurements of dissolved gas concentrations to quantity oxygen turnover in the hyporheic zone

ESR 16

From 12/2014

Principal Investigator: Rolf Kipfer
Staff: Andrea Popp

Objectives of this project:

• to carry out on-site in situ and quasi-continuous dissolved gas measurements using membrane inlet mass-spectrometry (MIMS), including further instrument developments towards miniature and longterm autonomous system
• to determine O_² turnover as overall measure for chemical and microbiological degradation processes on environmental relevant scales (minutes - days, 10^-1 - 1000 m)
• to use dissolved noble gases to determine water residence times
