Cardikarst, Croatia, Samograd cave, spot measurement

We are happy to announce that our latest scientific paper, “CO₂ Emission from Caves by Temperature-Driven Air Circulation—Insights from Samograd Cave, Croatia” has been published in the journal Climate.

This study explores CO₂ emissions from caves driven by temperature-induced air circulation, with a focus on Samograd Cave in Croatia. The data were collected by the monthly spot measurements which can provide very good insight into cave microclimate. The findings provide valuable insights into CO₂ dynamics in karst systems, which are essential for understanding CO₂ budget in karst and preserving these unique ecosystems.

Conceptual model of CO2 dynamics in Samograd Cave (pink = CO2). In summer (a), root respiration and soil microbial activity produces CO2 which fills the spaces inside the limestone, creating a CO2 reservoir that also fills the cave. In winter (b), cold air inflow pushes CO2 out of the cave. The resulting low pCO2 in the cave increases the transfer of CO2 from the ground reservoir to the cave’s atmosphere, being further exported via the temperature driven air circulation (drawn by A. Persiou).
