Karstic Aquifers—Simple or Hybrid Systems? Thermal Stories from Maaras Cave, Greece

Karst systems, such as caves, provide a unique opportunity to study the groundwater from inside in contrast spring studies, where hydrographs, chemographs, and thermographs show an integrated signal entire catchment aquifer. Studies karst springs that recharge conduit characteristics significantly influence how temperature is transmitted thus could inform on structure of underground flow paths. Here, we present monitoring data two-year-long 10 km long river cave, Maaras, northern Greece. Our five measuring stations along cave stream different paths transform signal. The area consists polje impacting conditions change seasonally diffuse concentrated. Diffuse stabilizes regardless conditions. However, fluctuations occur four time scales: seasonal, event-based, diurnal, hourly, indicating passage Interaction between in-cave porous aquifer clastic sediments strongly impacts alteration thermal through cave: are damped, raised.
