Paleo-archives are essential for our understanding of species responses to climate warming, yet such archives extremely rare in the Arctic. Here, we combine morphological analyses and bulk-bone metabarcoding investigate a unique chronology bone deposits sealed high-latitude Storsteinhola cave system (68°50′ N 16°22′ E) Norway. This deposit dates period warming from end Late Glacial [~13 thousand calibrated years before present (ka cal B.P.)] Holocene thermal maximum (~5.6 ka B.P.)....
An abundance and diverse range of prehistoric fishing practices was revealed during excavations between 2012 2022 at the construction site Femern Belt Tunnel, linking islands Lolland (Denmark) (Germany). The waterlogged parts Syltholm Fjord yielded well preserved organic materials, including remains wooden fish traps weirs, numerous vertical stakes posts driven into former seabed – evidence long term using stationary structures from Mesolithic to Bronze Age ( c. 4700–900 cal BC). Here, we...
Our knowledge about the glaciation history in Russian Arctic has to a large extent been based on geomorphological mapping supplemented by studies of short stratigraphical sequences found exposed sections. Here we present new geochronological data from Polar Ural Mountains along with high‐resolution sediment record Bolshoye Shchuchye, largest and deepest lake mountain range. Seismic profiles show that contains 160‐m‐thick sequence unconsolidated lacustrine sediments. A well‐dated 24‐m‐long...
Evidence of a dynamic Holocene glacial history is preserved in the terrestrial and marine archives St. Jonsfjorden, small fjord‐system on west coast Spitsbergen, Svalbard. High‐resolution, remotely sensed imagery from environments was used to construct geomorphological maps that highlight an intricate entire fjord‐system. The geomorphology stratigraphy indicate early local glacier advance constrained Lateglacial–early transition. Identification 14 C dating thermophilous bivalve mollusc...
Abstract Sediment cores from lakes Kormovoye and Oshkoty in the glaciated region of Pechora Lowland, northern Russia, reveal sediment gravity flow deposits overlain by lacustrine mud gyttja. The sediments were deposited mainly during melting buried glacier ice beneath lakes. In Lake Kormovoye, differential dead caused lake bottom to subside at different places times, resulting sedimentation erosion occurring only some few metres apart shifting locations, as further inversion bottom. Basal...
A 22 m long sediment core from Lake Yamozero on the Timan Ridge in northern Russia has provided evidence of intriguing climatic shifts during last glacial cycle. An overall shallowing lake is reflected lower part cores, where pollen indicates a transition steppe vegetation to interstadial shrub‐tundra. These beds are capped by well‐defined layer compact clay deposited relatively deep water, shows surrounding spruce forests and warmer‐than‐present summer temperatures. The most conservative...
Abstract Late Quaternary sedimentary units at Kongsfjordhallet, NW Svalbard, represent five cycles of glaciations and subsequent deglaciations during high relative sea levels. The level events are interpreted as glacioisostatically induced imply preceding regional glaciations, which we constrain in time by luminescence radiocarbon ages to just prior ~ 195, 130, 85, 60, 15 ka. Combined with the stratigraphical record from nearby Leinstranda identify six, possibly seven, major glacial advances...
