Short summary
Greenhouse gas emissions from dry aquatic sediments are probably globally relevant. However, they are difficult to measure because of the often rocky substrate. We tested the performance of different materials to seal a closed chamber to stony ground both in laboratory and field experiments. Pottery clay was a convenient sealing material, while the use of on-site material produced artefacts. We confirmed that CO2 fluxes from dry aquatic sediments were similar to fluxes from normal soils.
