Dispersion of artificial tracers in ventilated caves
Claudio Pastore, Eric Weber, Frédéric Doumenc, Pierre-Yves Jeannin, and Marc Lütscher

  • Artificial CO2 was injected in ventilated karst conduits (caves and mines), to assess the airflow
  • Geometrical conduit parameters, air velocity, and tracer dispersion were also carried out
  • The 1-D advection-dispersion model was compared with measured breakthrough curves
  • The theory of dispersion is also compared with dipersion inferred from field data
  • BTC tailing may stem from dead-flow zones that enhance aerosol deposition


A world review of fungi, yeasts, and slime molds in caves
Karen J. Vanderwolf, David Malloch, Donald F. McAlpine, and Graham J. Forbes


4D flow pattern of the longest cave in the Eastern Alps (Schönberg-Höhlensystem, Totes Gebirge)
Lukas Plan, Eva Kaminsky, Pauline Oberender, Clemens Tenreiter, and Maximilian Wimmer

  • Speleogenesis of a 156 km long and 1061 m deep Alpine cave system is studied
  • Arrangement of passages at two slightly inclined planes is confirmed as speleogenetic phases
  • Morphological observations reveal a reversal of flow-direction through time
  • According to current hydrological conditions, a dual flow is proposed
  • Unlike other karst massifs in the NCA, sediments support autogenic recharge for Totes Gebirge


Subaqueous carbonate speleothems as paleotemperature archives – clumped isotope thermometry and stable isotope compositions of inclusion-hosted water
Attila Demeny, Ágnes Berentés, László Rinyu, Ivett Kovács, Gergely Surányi, and Magdolna Virág

  • Subaqueous speleothems yield reliable clumped isotope temperatures
  • Calcite-water oxygen isotope thermometry seems to work for subaqueous speleothems


Climate monitoring in the Caumont cave and quarry system (northern France) reveal near oxygen isotopic equilibrium conditions for carbonate deposition
Ingrid Bejarano-Arias, Carole Nehme, Sebastian Breitenbach, Hanno Meyer, Sevasti Modestou, and Damase Mouralis

  • We monitored air temperature, dripwater stable isotopes and modern carbonate, deposited on glass plates at Caumont
  • Dripwater δ18O values reflect thorough mixing in the epikarst and some bias towards the winter season
  • Modern calcite δ13C indicate that prior carbonate precipitation might occur during summer
  • Modern carbonate deposition analysis showed the isotope system is at/very near isotope equilibrium
  • Our results show that Caumont cave is suitable for the study of climate trends in the past


Reverse pseudo-gours: a new sub-type of folia observed in the Nerja Cave (SE Spain)
Cristina Liñán Baena, Concepción Jiménez de Cisneros, Yolanda Del Rosal, and Paolo Forti

A new sub-type of folia has been described

Their genesis and evolution occur just at the air-water interface

Feeding water supersaturation degree extremely low

Slow and progressive lowering of the water level

Genesis: precipitation of minerals by rapid degassing of CO2 from water and/or evaporation.


Rates of diagenesis of tropical insectivorous bat guano accumulations: implications for potential paleoenvironmental reconstruction
Donald A. McFarlane and Joyce Lundberg

  • In tropical, wet guano, maximum acidity, temperature, and k values occur at depths of ~10-30 cm
  • Guano moisture level is the most significant control on k
  • Guano k values can have an enormous range – from 0.01 in wet tropical caves, down to 3 x 10-6 in extremely dry caves
  • SEM studies demonstrate that 3 kyr old guano in extremely dry conditions is essentially unaltered
  • Chitin survival under favorable conditions can thus be extrapolated to timescales of 105 years
