  • Holocene Hydroclimate Variability in Central Scandinavia Inferred from Flood Layers in Contourite Drift Deposits in Lake Storsjön

    Open AccessInga Labuhn, Dan Hammarlund et al.ARTICLEQuaternary2018

    Despite the societal importance of extreme hydroclimate events, few palaeoenvironmental studies of Scandinavian lake sediments have investigated flood occurrences. Here we present a flood history based on lithological, geochemical and mineral magnetic records of a Holocene sediment sequence collected from contourite drift deposits in Lake Storsjön (63.12° N, 14.37° E). After the last deglaciation, the lake began to form around 9800 cal yr BP, but…

  • New pollen evidence from Nariani (Georgia) for delayed postglacial forest expansion in the South Caucasus

    Open AccessErwan Messager, Sébastien Nomade et al.ARTICLEQuaternary Research2017

    The nature and timing of environmental changes throughout the last glacial-interglacial transition in the South Caucasus, and more widely in eastern Europe, are still not fully understood. According to certain pollen records, forest expansion occurred in many areas several millennia after what is considered worldwide as the onset of the Holocene. The current problem we face is that the time lag in forest expansion varies from one sequence to anot…

  • Years of paleostorm activity in the NW Mediterranean Sea in response to Holocene climate events

    Open AccessPaul Sabatier, Pierre Sabatier et al.ARTICLEQuaternary Research2012

    A high-resolution record of paleostorm events along the French Mediterranean coast over the past 7000 years was established from a lagoonal sediment core in the Gulf of Lions. Integrating grain size, faunal analysis, clay mineralogy and geochemistry data with a chronology derived from radiocarbon dating, we recorded seven periods of increased storm activity at 6300–6100, 5650–5400, 4400–4050, 3650–3200, 2800–2600, 1950–1400 and 400–50 cal yr BP (…

  • A sedimentary record of Holocene surface runoff events and earthquake activity from Lake Iseo (Southern Alps, Italy)

    Open AccessStefan Lauterbach, Emmanuel Chapron et al.ARTICLEThe Holocene2012Citada por: 4Referencias: 12

    This study presents a record of Holocene surface runoff events and several large earthquakes, preserved in the sediments of pre-Alpine Lake Iseo, northern Italy. A combination of high-resolution seismic surveying, detailed sediment microfacies analysis, non-destructive core-scanning techniques and AMS 14 C dating of terrestrial macrofossils was used to detect and date these events. Based on this approach, our data shed light on past seismic activ…

  • Biotic response to rapid climatic changes during the Late Glacial

    Open AccessBrigitta Ammann, U Eicher et al.ARTICLEGeographica Helvetica2008Referencias: 1

    Organisms can respond to rapid climatic changes in three ways: 1) adaptation by evolution, affecting physiology and morphology), 2) migration and population dynamics including biogeographical changes) and 3) extinction local or global). Here, the focus is on examples of the second type. Organisms, whether algae, trees, or animals, find their ecological niches in a multi- dimensional space of gradients such as temperature winter, summer, means or …
