Abstract

Istraživanje mikroklimatskih parametara u speleološkim objektima doprinosi boljem razumijevanju i proučavanju fizikalno–kemijskih procesa u klimatološkim, geomorfološkim, geoekološkim te biološkim istraživanjima. U ovom radu se istražuje mikroklima ulaznih dijelova speleoloških objekata te površine u njihovoj neposrednoj blizini na području Lomske dulibe i Rožanskih kukova. Glavno istraživanje obavljano je u gornjem dijelu Ledene jame u Lomskoj dulibi (-50 m) gdje je zabilježena znatna dinamika akumulacije snijega i leda u proteklih 20-ak godina. U svrhu interpretacije izvedena su mjerenja u razdoblju od 22. 09. 2012. do 29. 09. 2013. godine u Lomskoj dulibi, zatim na lokalitetu Rožanski kukovi od Patuljkove špilje do ulazne dvorane jame Sirene, te su korišteni podaci GMP Zavižan. Na svim lokacijama mjereni su temperatura i relativna vlažnost zraka, dok su tlak, strujanje zraka, temperatura stijene te koncentracija ugljikovog dioksida mjereni na odabranim lokacijama. Osim terenskih izlazaka u svrhu postavljanja memorijskih termohigrografa i prikupljanja podataka u rujnu 2012. i 2013. godine, mjerenja su obavljana i tijekom Speleološke ekspedicije „Sirena“ na Rožanskim kukovima u srpnju i kolovozu 2013. godine.

Abstract (english)

The cave research of microclimate parameters contributes to a better understanding and study of physical and chemical processes within climatological, geoecological and biological research. This thesis studies the microclimate of the entrances and surrounding areas of the caves around Lomska duliba and Rožanski kukovi. The main research was focused on the upper parts of the Ice pit in Lomska duliba (Ledena jama in Lomska duliba) (-50 m), where the dynamics of accumulation of snow and ice was significant in the last 20 years. For a better interpretation, in the period from September 22th 2012 to September 29th, 2013 additional measurements were performed in the area of Lomska duliba and from Patuljak cave to the entrance chamber of Sirena pit in the Rožanski kukovi area. Additional data from meteorological station Zavižan were also used. Air temperature and relative humidity were measured on every location, whereas air pressure, air flow, rock temperature and the concentration of carbon dioxide were measured on selected locations only. Multiple expeditions were carried out in September of 2012 and 2013 for the purpose of setting up memory thermohygrographs and collecting data. Additional data was collected during the speleological expedition „Sirena“ on Rožanski kukovi area in July and August of 2013.
