The International Journal of Speleology is the official journal of the Union Internationale de Spéléologie since 1978 and was founded in 1964. It is a double-blind, peer-reviewed, international scientific journal that publishes research and review articles concerning all sciences involved in karst and caves, such as geology, geomorphology, hydrology, archeology, paleontology, (paleo)climatology, cave meteorology, (geo)microbiology, environmental sciences, physics, chemistry, mineralogy, etc. IJS is published three times per year.

Articles are open access at http://scholarcommons.usf.edu/ijs. The journal is abstracted and indexed in the following services: Directory of Open Access Journals, ISI Thomson Services (Science Citation Index-Expanded including the Web of Science, ISI Alerting Service, Current Contents/Physical, Chemical and Earth Sciences), Bibliography & Index of Geology (GeoRef, Cambridge Scientific Abstracts, EarthScienceWISE (Oxmill Publishing), EBSCO publishing, Geobase, Speleological Abstracts (UIS), Ulrich’s Periodical Directory ™, BIOSIS Zoological record, SCOPUS (Elsevier), and SCImago Journal and Country Rank.

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


Speleogenesis in a lens of metamorphosed limestone and ankerite: Ochtiná Aragonite Cave, Slovakia
Pavel Bella, Pavel Bosák, Petr Pruner, Helena Hercman, Katarína Pukanská, Karol Bartoš, Ľudovít Gaál, Dagmar Haviarová, Peter Tomčík, and Šimon Kdýr

  • Carbonic acid speleogenesis enhanced due to ankerite oxidation
  • Solution flat ceilings and inward-inclined smooth facets in a limestone cave
  • Solution facets developed in flat-roofed passages as well as in vaulted halls and passages
  • The Brunhes/Matuyama boundary and Jaramillo magnetozone recorded in cave sediments
  • Slow depositional rate of cave sediments determined from magnetostratigraphy data


Monitoring photosynthetic activity using in vivo chlorophyll a fluorescence in microalgae and cyanobacteria biofilms in the Nerja Cave (Malaga, Spain)
Yolanda Del Rosal, Juan Muñoz-Fernández, Paula S.M. Celis-Plá, Mariona Hernández-Mariné, Félix Álvarez-Gómez, Salvador Merino, and Félix L. Figueroa

  • Monitoring of in vivo Chl a fluorescence is an efficient tool to prevent biodeterioration processes
  • Photosynthetic activity is related with values of temperature, relatively humidity and CO2 in the air
  • The biofilms could survive under stress environment
  • Higher environmental values probably alleviate the photoinhibition as a supply in the system Irradiance is not an adequate key factor to control microorganism growth in the Nerja Cave
