Abstract:

<b>Summary:</b><br> Data of the "density-driven dissolution of CO2 in karst water" column experiment. A laboratory column was filled with tapwater (water level 5,55 m) and exposed it to an elevated gaseous CO2-concentration, roughly 50 times the current atmospheric concentration (20000 +/- 5000 ppm). After stripping the water with ambient air, it was initially in equilibrium with atmospheric conditions. Then, the concentration of dissolved CO2 was measured over a time period of 60 days in two different depths in the column. Measuring points are in the column air, 1 m below water level and 0,15 m above ground. CO2-air concentration was provided using an air-membrane pump (KNF N86 KTE) and a 100 l TEDLAR bag (for more detailed information look into the related publication <a href="https://doi.org/10.1002/essoar.10507661.1">Class 2021 et al.</a>)<br> <br> <b>Raw Data:</b><br> Raw data provided by GMP252 CO2 sensor probes, data accessed from ADL-MX Advanced Datalogger via ADL-C software<br> <u>Sensor positions:</u><br> CO2_10: column air<br> CO2_20: 1 m below water surface<br> CO2_40: 0.15 m above ground/5.40 m below water surface<br> <br> <b>Processed Data:</b><br> Processed Data calculated after formula in the related publication <a href="https://doi.org/10.1002/essoar.10507661.1">Class 2021 et al.</a><br> MC: manufacturer correction<br> OC: own correction<br> <br> <b>Sherwood:</b><br> Calculations for Sherwood number.
