Radon as a natural radioactive tracer of permanent air movements in the Nied?wiedzia Cave (Snie?nik K?odzki, Sudety Mts.), 1998, Przylibski Tadeuszandrzej, Piasecki Jacek

Radon concentration changes in the air of two caves in Poland, 1999, Przylibski T. A. ,
The paper presents spatial and seasonal radon concentration changes in the air of two caves in Poland on the basis of measurements during 1995-1997. A process of seasonal radon concentration changes in the caves' air was identified, based on research on radon occurrence in caves carried out for over 20 years. A major role in this process was ascribed to ventilation caused by atmospheric temperature changes. High radon concentrations are observed in the warm half-year (May-August), when the average air temperature exceeds the average temperature of the cave interior. Low concentrations occur, however, in the cold half-year (December-January), and a relatively sharp increase or decrease in radon concentration is related to changes in atmospheric temperatures relative to the average temperature in the cave interior. The amplitude of these radon concentration changes may reach several kBq m(-3). In the Radochowska Cave the lowest monthly radon concentration (0.06 kBq m(-3)) was recorded in December 1996, while the highest (1.37 kBq m(-3)) was observed in August 1996. In the Niedzwiedzia Cave the lowest value (0.10 kBq m(-3)) was observed in January 1997 and the highest (4.18 kBq m(-3)) was noted in March 1997. The spatial variation of radon concentrations is mainly due to the morphology of the chambers and corridors of a cave, and by the distance between the measurement point and the entrance holes. As a rule, locations further from the entrance have poorer ventilation and higher radon concentrations. (C) 1999 Elsevier Science Ltd. All rights reserved

Fungi isolated from Niedźwiedzia Cave in Kletno (Lower Silesia, Poland), 2013, Ogrek Rafal, Lejman Agnieszka, Matkowski Krzysztof

Niedźwiedzia Cave is the most beautiful cave in Poland, discovered in a block of Cambrian marbles. It is the most important part of the reserve established in 1977. The cave is located within the Kłodzko Valley, in Śnieżnik Mt. Massif, in Kleśnica Stream Valley and was discovered in 1966 while working in a quarry. The study aimed at first mycological evaluation of the air and the rocks in Niedźwiedzia Cave. Nine species of filamentous fungi and a yeast species were isolated from the air sampled in the cave, whereas from the rocks - nine species of filamentous fungi and two species of yeasts were collected. Rhizopus stolonifer was the species most frequently isolated from the air and from the rocks, while the least isolated from the air was Sclerotinia sclerotiorum. Among the species found in the rock, the least frequently collected were Fusarium oxysporum and the yeast Rhodotorula rubra.


TRITIUM AND H, O AND C STABLE ISOTOPES AS A TOOL FOR TRACKING OF WATER CIRCULATION IN THE NIEDŹWIEDZIA CAVE SYSTEM (SUDETES, POLAND), 2013, Gą, Siorowski M. Hercman H.

 

Water circulation in Niedźwiedzia Cave system is complicated. The system is fed by direct infiltration of precipitation, infiltration from the surface stream and, possibly, by rising flow from deep sources. The cave is drained by system of karst springs in the Kleśnica stream valley, but some part of water flows across border ridge and occurs in Morava stream valley, Czech Republic (Ciężkowski et al. 2009). We tried to use tritium and stable isotopes to describe hydrology of the cave system and analyzed 155 water samples for stable isotopes and 38 water samples for tritium content. The Niedźwiedzia Cave system is composed of three levels of halls and galleries. In the upper level, stable isotope composition in drip water plots close to the local meteoritic water line (LMWL) on the δ18O vs δD diagram. It varies during the year similar to stable isotope composition of precipitation (i.e. low δ18O values during winters and higher δ18O during summers). The delay between isotopic signal in precipitation and drip water is ~10–14 days and this can be interpreted as a time of infiltration from the surface to the cave upper level. The correlation between isotopic composition of precipitation and drip water is not observed in the lower level of the cave system. There isotopic composition of drip water is more stable during the year. We use tritium dating method to estimate the age of this water. It has shown that infiltration time to the lower level is 1.4±0.3 year. The “oldest” water was found in karst spring draining the cave system. The estimated transit time is 3–4 years and suggest admixture of some “old” water that was not sampled in the cave.
