The middle to Late Holocene environment on the Iturup Island (Kurils, North Western Pacific)
Permafrost is warming at a global scale
Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrost temperature change has been compiled. Here we use a global data set of permafrost temperature time series from the Global Terrestrial Network for Permafrost to evaluate temperature change across permafrost regions for the period since the Internationa…
Changes in temperature and water depth of a small mountain lake during the past 3000 years in Central Kamchatka reflected by a chironomid record
A Process- and Provenance-Based Attempt to Unravel Inconsistent Radiocarbon Chronologies in Lake Sediments
Aquatic macrophytes from a lacustrine environment are highly prone to a reservoir effect, resulting in an overestimation of age. This is often caused by the incorporation of dissolved carbon (CO 2 and HCO 3 – ) through photosynthesis from lake waters that have a different 14 C activity than the atmosphere. The atmosphere-water disparity is often produced by a mixing of carbon between the water body and its terrestrial surroundings, a process high…
Early to mid-Holocene lake high-stand sediments at Lake Donggi Cona, northeastern Tibetan Plateau, China
Lake high-stand sediments are found in three onshore terraces at Lake Donggi Cona, northeastern Tibetan Plateau, and reveal characteristics of hydrological changes on lake shorelines triggered by climate change, geomorphological processes, and neo-tectonic movements. The terraces consist of fluvial–alluvial to littoral-lacustrine facies. End-member modeling of grain-size distributions allowed quantification of sediment transport processes and rel…
Holocene climate conditions in central Yakutia (Eastern Siberia) inferred from sediment composition and fossil chironomids of Lake Temje
Last glacial vegetation reconstructions in the extreme-continental eastern Asia
Holocene environments and climate in the Mongolian Altai reconstructed from the Hoton-Nur pollen and diatom records
Environmental Changes in the Mongolian Altai During the Holocene
Based on palynological and diatom analyses of the sediment core from Lake Hoton Nuur situated at 2083 m asl, environmental changes in the Mongolian Altai during the Holocene are described. The results suggest that the Late Pleistocene and Early Holocene (11.5–10.7 ka) climate of that area was cold and arid, and plant associations were of a steppe type. The Middle Holocene (9.3–6.5 ka) climate was warm and humid, resulting in the expansion of fore…
Yr-long records of annual air temperature and precipitation over southern Siberia inferred from Teletskoye Lake sediments
A unique 800-yr-long record of annual temperatures and precipitation over the south of western Siberia has been reconstructed from the bottom sediments of Teletskoye Lake, Altai Mountains using an X-ray fluorescence scanner (XRF) providing 0.1-mm resolution timeseries of elemental composition and X-ray density (XRD). Br content appears to be broadly correlative with mean annual temperature variations because of changes in catchment vegetation pro…
Environmental changes in the northern Altai during the last millennium documented in Lake Teletskoye pollen record
A high-resolution pollen record from Lake Teletskoye documents the climate-related vegetation history of the northern Altai Mountain region during the last millennium. Siberian pine taiga with Scots pine, fir, spruce, and birch dominated the vegetation between ca. AD 1050 and 1100. The climate was similar to modern. In the beginning of the 12th century, birch and shrub alder increased. Lowered pollen concentrations and simultaneous peaks in herbs…
