Microbiota entrapped in recently-formed ice: Paradana Ice Cave, Slovenia.

ABSTRACT: Paradana is one of the biggest ice caves in Slovenia, with an estimated ice volume of 8,000 m³. Reflecting climatological conditions, the cave ice undergoes repeated freeze-thaw cycles and regular yearly deposition of fresh ice. Three distinct ice block samples, collected from the frozen lake in May 2016, were analysed to obtain data on ice physicochemical properties and the composition of associated microbiota. Isotopic composition of the ice samples (¹⁸O, ²H) and a local meteoric water line (LMWL) constructed for monthly precipitation at Postojna were used to estimate the isotopic composition of the water that formed the ice, which had high values of deuterium excess and low concentrations of chloride, sulphate and nitrate. The values of total organic car
