“…We estimated the glacier's ELA by using the area altitude balance ratio (AABR) method, which is considered to be nonsensitive to glacial hypsometry (Furbish and Andrews, 1984; Osmaston, 2005; Rea, 2009; Pellitero et al, 2015). We applied the global median AABR value of 1.6 calculated by Zasadni et al (2020) from Rea's (2009) monitored glacier data set. The AABR 1.6 method is commonly used in modern studies in the Alps (Rea, 2009; Federici et al, 2016) and the Carpathian–Balkan area (Ruszkiczay-Rüdiger et al, 2017; Temovski et al, 2018; Zasadni et al, 2020).…”

“…Similarly, due to the small size of south-facing glaciers (<1 km 2 ), the interpretation of the ELA trend was carried out solely for the glaciers on the northern slope of the Rodna Mountains. The basic morphometric and hypsometric parameters of palaeoglaciers, such as the length, aspect, area, maximal and minimal thickness, volume, z min, z max, z med (AAR 0.5), z mean (AABR 1.0) (Zasadni et al, 2020) were calculated for each glacier.…”

In the eastern Carpathians the legacy of glaciation is preserved in several isolated mountain massifs. This paper presents new mapping results of glaciated valley land systems in the Rodna Mountains, the highest part of the eastern Carpathians (2303 m above seal level). In most of the glacial valleys, the maximal Pleistocene extent is marked by freshly shaped moraines, which are referred in this study as the Pietroasa glacial stage and regarded as the last glacial maximum (LGM) advance. Only in three valleys do older Şesura glacial stage moraines (pre-LGM, likely Marine Oxygen Isotope Stage 6) occur. On the basis of the geomorphological record, we reconstruct the extent, surface geometry, and equilibrium line altitude (ELA) of Pietroasa-stage glaciers. The local ELA pattern of north-exposed glaciers in the Rodna Mountains shows a rising trend towards the southeast, which suggests dominant snow-bearing winds and orographically induced precipitation from the west. This finding fits well with the dominant palaeo-wind direction inferred from other Carpathian proxies and confirms the dominance of zonal circulation pattern during the global LGM in central eastern Europe.

“…Marine records from the western Iberian margin also pointed to 5-6°C of warming at the onset of the B-A (Martrat et al, 2007). These warmer conditions also favoured the recession of glaciers across most European mountain ranges, such as in the Alps at 15.9-14.3 cal ka BP (Ivy-Ochs, 2015), Tatra Mountains at 14.8-14.2 ka (Zasadni et al, 2020), Taurus Mountains at 14.6 ± 2.8 ka (Ciner and Sarikaya, 2015), as well as the Scandinavian Ice Sheet, which recorded a shrinking trend starting at 14.6 cal ka BP (Mangerud et al, 2013).…”

The Upper Garonne Basin included the largest glacial system in the Pyrenees during the last glacial cycle. Within the long-term glacial retreat during Termination-1 (T-1), glacier fluctuations left geomorphic evidence in the area. However, the chronology of T-1 glacial oscillations on the northern slopes of the Central Pyrenees is still poorly constrained. Here, we introduce new geomorphological observations and a 12-sample dataset of 10 Be cosmic-ray exposure ages from the Ruda Valley. This U-shaped valley, surrounded by peaks exceeding 2800 m a.s.l., includes a sequence of moraines and polished surfaces that enabled a reconstruction of the chronology of the last deglaciation. Following the maximum ice extent, warmer conditions prevailing at ~15-14 ka, during the Bølling-Allerød (B-A) Interstadial, favoured glacial retreat in the Ruda Valley. Within the B-A, glaciers experienced two phases of advance/stillstand with moraine formation at 13.5 and 13.0 ka. During the early Younger Dryas (YD), glacial retreat exposed the highest surfaces of the Saboredo Cirque (~2300-2350 m) at 12.7 ka. Small glaciers persisted only inside the highest cirques (~2470 m), such as in Sendrosa Cirque, with moraines stabilising at 12.6 ka. The results of this work present the most complete chronology for Pyrenean glacial oscillations from the B-A to the YD.

“…The knowledge about duration and thickness of snow cover plays also curtail role in correction of cosmogenic exposure ages which attempt to date Quaternary landforms in mountain environments, like rock-slope failures and glacial moraines (e.g. Engel et al, 2015;Pánek et al, 2017;Makos et al, 2018;Zasadni et al, 2020). 1).…”

Over the last decades, snow seasons in Europe were reported to become shorter with lower abundance of snow. However, at some stations situated above certain elevation, the amount of snow cover was found to be increasing. This is also the case of high mountains in Slovakia, where number of snow-related studies showed some differences related to the elevation. In this study we report on the trends of selected snow cover characteristics such as the number of days with snow cover (DSC) for 1, 10 and 20 cm depths, summed snow depths (SSD) and mean snow depths (MSD). The data used in this study were collected by the Slovak Hydrometeorological Institute (SHMI) at eight stations in the Tatra Mountains region during the 39 seasons 1981-2020 (01/07 to 30/06 the following year). Some increasing trends were observed for stations above 1100 m while stations below this elevation had generally decreasing estimates. The DSC for 1 cm ranged from 297 days at station elevated at 2635 m a.s.l. to 25 days for station at 640 m a.s.l. The MSD ranged from 100 to 7 cm on average for the whole period. Apart from global warming, other factors play role, and these can be complex in the mountainous regions making any trends more ambiguous to interpret.
