Water sampling. Measuring dissolved CO2 (alkalinity) in the waters by titration in the field. A measure of how much each river is affecting the climate by removing carbon dioxide
Sampling and Filtering. Again. Apparently, there was a question asking why we filter the water – so here is the answer: Filtering to remove the suspended particles, so we can analyse the dissolved fraction, and the suspended fraction separately. The former tells us about chemical weathering and CO2 removal, and the latter about physical erosion (glacial grinding).
