In our mesocosm studies, sampling plays a pivotal role in understanding the impact of the applied rock on carbon removal. By collecting soil and water samples from both the experimental mesocosms and the reference ones, we are establishing a basis for comparison, crucial for evaluating the effectiveness of the aggregate application.

The focus on soil and pore water studies is strategic. These samples provide a wealth of information on changes in mineralogical and geochemical parameters, which are key indicators of how the introduced rock affects the environment. The assessment of these parameters will yield insights into the total inorganic and organic carbon content, as well as the dissolved inorganic carbon.

By meticulously analyzing these components, we are essentially piecing together the puzzle of carbon removal. Understanding the fluctuations in carbon content across different forms and mediums allows for a comprehensive calculation of the amount of carbon dioxide that has been effectively taken out of the system due to the rock application.

In essence, the sampling and subsequent analyses serve as the bridge between the physical application of the rock and the quantifiable impact it has on carbon sequestration. This methodical approach helps in reliably determining the success and efficiency of our mesocosm interventions in removing carbon dioxide from the environment.
