“…The lowest δ 18 O values were recorded during winter months. Similar conclusions can be derived from stalagmite records gathered and published by SISAL group (Kern et al, 2019). Moreover, the δ 18 O records from DCS stalagmites (Figure 7a and b) have similar pattern to zonal mean temperature reconstructions for 30–90° N latitude (Marcott et al, 2013; Figure 7c).…”

Five stalagmites from the Demänová Cave System (DCS, Western Carpathians, Slovakia), spanning the period from 13,000 to 500 a BP, were analyzed for their oxygen and carbon stable isotopic composition of the calcite. The isotopic data obtained from several stalagmites located in one cave system allow us to separate the changes of regional/global importance from the local changes. Oxygen isotope ratios point to dynamic changes in the environment at the onset of the Holocene. Despite the local differences, carbon isotope data express the gradual and steady development of vegetation on the surface above the cave from the beginning of the Holocene until 6,000 a BP. The oxygen isotope values in the DCS stalagmites are higher than that derived from the Rayleigh distillation model until approximately 9,000 a BP, suggesting (1) an increase in the isotopic gradient to the east of Europe, probably caused by a different seasonality in precipitation amount or (2) different sources of meteoric water, transported from the Mediterranean and Black Sea region, in Central and Eastern Europe compared to the Western, circum-Atlantic part of the continent. The younger part of the DCS records falls in the range described by the model and points to the increasing role of the westerlies in the determination of the climatic conditions of Central Europe during middle- and late-Holocene.

We present 100‐ka multiproxy palaeoenvironmental records from three stalagmites collected in different caves located in the Tatra Mountains on the Polish/Slovakian border. A combination of three records from one mountain region helps to estimate local factors controlling the recorded proxies and separate them from regional/global patterns. The studied stalagmites react to the same environmental changes in different ways due to the differences in their local settings. Furthermore, the analysed records show environmental changes from relatively cold and dry climates to interglacial conditions of MIS 5e. One episode of a colder climate during the MIS 6/MIS 5e transition similar to Dryas periods is observed in all studied stalagmites. The δ18O record from the MAG‐1 stalagmite is most similar to the GRIP record. During the MIS 5e, the δ18O record from the MAG‐1 stalagmite e xhibits a pattern similar to the records from the western part of the European continent. This finding suggests that the Atlantic Ocean was an important source of moisture for the region. The observed rapid change of δ18O, δ13C, Sr and Si proxies from the MAG‐1 and Dz‐1 stalagmites after 109 ka are potentially related to a drier and colder climate.

“…The main factor shaping the δ 18 O composition of western and central European speleothems is temperature (Moseley et al, 2015;Kern et al 2019;Comas-Bru et al, 2020). Exemplary, stalagmite form Cobra cave, located on the northern coast of Spain (Fig.…”

Abstract. The speleothems are an important source of paleoclimatic information in the land environment. The basic advantages of speleothems are the high potential of preservation; the possibility of precise dating by the U-series method; many different proxies like stable isotopes, trace elements, and microfabric which can be interpreted in the term of paleoclimate. The JS9 stalagmite was collected in Demänová Cave System (Slovakia). Presently this region of Europe is under influence of transitional and continental climate. However, in the past, it could be under stronger influence of the continental climate during cold glacial episodes and under wetter transitional climate during interglacial. The multiproxy record of the JS9 stalagmite represents ca. 60 ka period (143–83 ka). The multiproxy interpretation of the JS9 record shows that long time tendencies of δ18O have thermal nature while the short time δ18O signal reflects changes in humidity. In opposition to the records from the Alps and the northern Tatra mountains, the δ18O record of JS9 has instant decrease episodes during Termination II.
