Northern Velebit Deep Caves

2013
Research of Northern Velebit started in the early 90s by Slovak cavers. From then on, each year at least one caving expedition is carried out in the Northern Velebit. In 22 years in the Northern Velebit area a total of 348 caves were explored of which three caves are deeper than 1, 000 m, five caves are deeper than 500 m, nine caves deeper than 200 m ...

Some deep caves in Biokovo Mountain (Croatia)

Geophysical research abstracts, 2014
A special attention was paid to the radon concentration measurement, and to chemical analyses of ground water. According to current speleological site classifications, the caves discovered at KM 1+415, KM 1+193, and KM 1+637, are large-size vertical speleological sites (caves) of an elbow shaped morphological type, characterized by the occurrence of ...

Catastrophe analysis of deep tunnel above water-filled caves

Journal of Central South University, 2019
To explore the influence of karst cavity pressure on the failure mechanisms of rock layers above water-filled caves, novel blow-out and collapse mechanisms are put forward in this study. The proposed method uses the nonlinear optimization to obtain the failure profiles of surrounding layered rock with water-filled cave at the bottom of the tunnel.

Adaptations of cave fishes with some comparisons to deep-sea fishes

Environmental Biology of Fishes, 2001
I provide my retrospective and prospective views on adaptations of cave fishes. I emphasize the history of my insights into cave adaptation from 45 years of research using surface, cave-spring, and cave species of amblyopsid fishes. My approach has been to use natural experiments and to always consider multiple hypotheses.

Geological explorations of North Velebit deep caves

2012
Speleološka istraživanja dubokih jama pružaju mogućnost za neposredan uvid u geološku građu terena duboko ispod površine. U okviru speleoloških ekspedicija u Lukinu jamu 1993. i 1994. godine obavljeno je uzorkovanje stijena po cjelokupnom profilu jame, izmjereni su položaji slojeva, pukotina i rasjeda te je na temelju dobivenih rezultata izrađen ...

Paleoclimate Archives of Deep Caves of Mt. Velebit

2013
Proučavanja špiljskih sedimenata kao paleoklimatskih arhiva teme su niza aktualnih studija u svijetu. Duboke jame Velebita (Paar i dr., 2008 ; Paar i dr., 2013) su kompleksni sustavi u kojima su zabilježene i sačuvane informacije o geološkim, geomorfološkim, hidrološkim i ekološkim uvjetima i procesima zbog čega predstavljaju odličnu sredinu za ...

Stygobiont ostracods from a deep cave Njemica (Biokovo Mt., Croatia)

2022
Njemica cave on Biokovo Mountain is the fifth deepest pit in the Republic of Croatia (-936 m). It is primarily a vertical speleological object characterized by the alternation of spacious large halls and large verticals. At the bottom of the pit is a deep siphon lake with an unclear hydrological regime.

Research in Calcretes and Other Deep Subterranean Habitats Outside Caves

2018
The outstanding difference between traditional subterranean fauna studies and those carried out recently in Australia is the Australian emphasis on the fauna that occurs deep underground, but outside caves, across large parts of the landscape. This work has shown that the Australian arid zone, particularly in the western half of the continent, is rich ...
