The role of GPR techniques in determining ice cave properties: Peña Castil ice cave, Picos de Europa [PDF]

, 2016
Producción CientíficaThe structure and ice content of ice caves are poorly understood. Ground penetrating radar (GPR) can provide useful insights but has only rarely been applied to ice caves.

Air pressure propagation through Wind Cave and Jewel Cave: How do pressure waves travel through barometric caves?

International Journal of Speleology, 2021
In barometric caves, air pressure gradients between the outside atmosphere and the cave induce strong bidirectional compensating currents, which control almost all elements of speleoclimatology, including air temperature, humidity, and CO2 dynamics ...

Numerical simulation of the dual laterolog response to fractures and caves in fractured-cavernous formation

Petroleum Exploration and Development, 2012
To study the response characteristics of dual laterolog in fractured-cavernous reservoirs, a model of fractures and caves was built, and the 3-D finite element method was utilized to simulate its logging responses. Caves of certain size have influence on

Cooling of hydrothermal fluids rich in carbon dioxide can create large karst cave systems in carbonate rocks

Communications Earth & Environment, 2023
Karst systems, comprising interconnected voids and caves, are ubiquitous in carbonate formations and play a pivotal role in the global water supply. Accumulating evidence suggests that a significant portion of the global karst is hypogenic, formed via ...

Iron Age to Medieval entomogamous vegetation and Rhinolophus hipposideros roost in south-eastern Wales (UK) [PDF]

, 2006
Karst cave systems are well developed in Wales (UK) and, in some instances, constitute important bat roosts. Ogof Draenen, near Blaenavon in south-east Wales, is the most recent major cave discovery (1994) with already > 70 km of passages explored ...
