Low impact sampling of speleothems – reconciling scientific study with cave conservation
Claire L.V. MacGregor, John C. Hellstrom, Jon D. Woodhead, Russell N. Drysdale, and Rolan S. Eberhard

  • Low impact method for speleothem sampling
  • Cave conservation best practice

PDF

Continuous color model as a tool to improve speleothem age model development
Celia Campa-Bousoño, Ángel García-Pérez, Ana Moreno, Miguel Iglesias, Hai Cheng, R Lawrence Edwards, and Heather Stoll

  • Relationship between color and growth rate is described by an exponential function
  • Color growth rate model is useful in guiding optimal locations for U-Th dating
  • Color growth rate model may enable a better age model to be built with fewer dates
  • Stalagmite color does not show consistent relationships with climate indicators

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

Air pressure propagation through Wind Cave and Jewel Cave: How do pressure waves travel through barometric caves?
Annika K. Gomell, Daniel C. Austin, Marc J. Ohms, and Andreas Pflitsch

  • Inside barometric caves, air pressure signals are delayed, smoothed and damped
  • These changes are caused by altitude differences and long response times of the caves
  • In Wind Cave, the related processes take place primarily in the entrance area
  • In Jewel Cave, the related processes take place primarily in the deep parts of the cave
  • Thus induced compensating currents control the caves' microclimate

Safe and effective disinfection of show cave infrastructure in a time of COVID-19
Hazel A. Barton

  • Showcaves have unique challenges to coronavirus disinfection
  • The chemistry of coronaviruses suggest they will adsorb to limestone
  • The chemistry of limestone surfaces is likely to inactivate coronaviruses
  • Effective disinfectants with minimal impact on caves were identified
  • Face masks and social distancing remain critical in preventing disease

The relative importance of wind-driven and chimney effect cave ventilation: Observations in Postojna Cave (Slovenia)
Lovel Kukuljan, Franci Gabrovsek, and Matthew Covington

  • Winds can enhance or diminish typical seasonal density-driven cave ventilation
  • The wind-driven effect is generated by variations in the wind pressure field
  • The effect depends on the cave configuration and its surface connections
  • This study provides a better understanding of cave climate and karst processes
