Uncovering an eruptive history using new tephra data from Argentine lacustrine cores linked to Chilean volcanoes in the southern segment of the Southern Volcanic Zone
This study examines tephra layers from lacustrine sediment cores collected in Patagonian Andean Range, correlating them with volcanic sources from the southern segment of the Southern Volcanic Zone (SVZ). Ten distinct tephra layers, spanning approximately the last 2000 yr, were identified across four cores from Lakes Rivadavia, La Zeta, Brychan, and Theobald, from ∼42°S to 44°S. Mostly geochemical and mineralogical analyses of tephra components (…
High-resolution radiocarbon and OSL cross-dating of Late Pleniglacial to Early Holocene aeolian succession and wildfire dynamics at the Łaskarzew site, eastern Poland
The chronology of Late Glacial and Early Holocene dune formation and wildfire activity at the Łaskarzew site, eastern Poland, was reconstructed using a combination of accelerator mass spectrometry (AMS) radiocarbon dating ( 14 C) and optically stimulated luminescence (OSL) dating. The stratigraphic profile records 13 aeolian-soil cycles, characterized by alternating phases of aeolian deposition, soil formation, and wildfire episodes, reflecting t…
Tracing storminess variability through seabed sediments in Puck Bay, southern Baltic Sea
Storms have severe impacts on coastal communities and infrastructure. The southern Baltic Sea coast is particularly vulnerable to storm surges, as it predominantly features barrier-type coast, and extensive areas of coastal lowlands are situated within 1.5 m above sea level. Due to the short instrumental record, our knowledge of the complex issue of storminess is relatively limited. Therefore, it is very important to extend the timespan of storm …
Radiocarbon dates from deposits sampled at the Vistula Spit canal excavation (Southern Baltic coast, Poland)
We report new AMS radiocarbon dates of 16 samples from the Holocene deposits of the Vistula Spit, a large coastal barrier landform on the Southern Baltic coast. Collection of the samples was conducted directly from the sedimentary succession excavated during 2020–2022 construction of the Vistula Spit shipping canal. The dated material represents several paleosol horizons and peat lenses buried in the dune deposits, as well as their substrate – be…

Monitoring of Modern Carbon Fraction in Disposable Packaging
Radiocarbon ( 14 C) methodology was used to investigate the presence of biocarbon in different bio-based disposable packaging products. Packaging waste contributes to a municipal solid waste, which is increasing environmental concerns and resulting in the enhancement of EU regulations that aim to reduce packaging waste. The 14 C amount in samples reflects how much of the biocarbon has been used. In this study, the concentration of 14 C was determ…
Determination of radiocarbon content in liquid fuel blends by accelerator mass spectrometry and liquid scintillation counting in the Gliwice radiocarbon and mass spectrometry laboratory

Resilience, rapid transitions and regime shifts
Rapid ecosystem transitions and adverse effects on ecosystem services as responses to combined climate and human impacts are of major concern. Yet few long-term (i.e. >60 years) quantitative observational time series exist, particularly for ecosystems that have a long history of human intervention. Here, we combine three major environmental pressures (land use, nutrients and erosion) with quantitative summer and winter climate reconstructions and…
