Intercambios de C02 suelo/cavidad en un sistema kárstico somero (Cueva de Altamira, Cantabria)
The monitoring system installed in Altamira Cave (Cantabria) is providing us a continuous record of microenvironmental data, for both cave atmosphere and air trapped in soil (air temperature,-atmospheric pressure, 222Rn, CO2 concentration). The karst system has a great importance in the global car...

| Sumario: | The monitoring system installed in Altamira Cave (Cantabria) is providing us a continuous record of microenvironmental data, for both cave atmosphere and air trapped in soil (air temperature,-atmospheric pressure, 222Rn, CO2 concentration). The karst system has a great importance in the global carbon cycle, not only far long-term cycles, but a/so far short-term ones. The C01 fluxes between the hypogea/ atmosphere and the externa/ soil air are controlled by differences of temperature and density of air, changes in atmospheric pressure and rainfa/1 regime. The local meteorologica/ conditions and the geometry of the cavity rule CO2 exchanges between cave atmosphere and air trapped in soi/. A temperature inversion (Tint > Text) and a great increase and stabilization in C01 levels takes place in Altamira Cave in autumn. Therefore, during this time the cave acts as a sink of atmospheric CO2• |
