Lake Ladoga in northwestern Russia is Europe's largest lake. The postglacial history of the basin for first time documented continuously with high temporal resolution upper 13.3 m a sediment core (Co1309) from part We applied multiproxy approach including radiographic imaging, (bio‐)geochemical and granulometric analyses. Age control was established combining radiocarbon dating varve chronology, latter anchored to correlated age lake close by. age‐depth model reveals onset glacial...
The Bronze Age Maikop kurgan is one of the most richly furnished prehistoric burial mounds in northern Caucasus. Its excavation 1897 yielded a set gold and silver tubes with elaborate tips decorative bull figurines. Interpretations these include their use as sceptres poles to support canopy. Re-examination objects, however, suggests they were used for communal drinking beer, integral filters remove impurities. If correct, objects represent earliest material evidence through long tubes—a...
Abstract Ground ice and sedimentary records of a pingo exposure reveal insights into Holocene permafrost, landscape climate dynamics. Early to mid‐Holocene thermokarst lake deposits contain rich floral faunal paleoassemblages, which indicate shrinkage decreasing summer temperatures (chironomid‐based T July ) from 10.5 3.5 cal kyr BP with the warmest period between 8 BP. Talik refreezing growth started about after disappearance lake. The isotopic composition (δ 18 O − 17.1 ± 0.6‰, δD −144.5...
The palaeoenvironment of the Karelian Isthmus area during Litorina Sea stage Baltic history, between 8.0 and 4.5 kyr BP (8.8‐5.2 cal. BP), was reconstructed by studying four sites located on in Russia. Methods included diatom pollen analyses, sediment lithostratigraphical interpretation 14C dating. brackish‐water (Litorina) transgression began c. 7.7 (8.45 BP) area. maximum occurred 6.7 5.7 (7.6‐6.5 depending glacio‐isostatic land uplift rate. Regarding vegetation, occurrence temperate...
Lake Ladoga hosts preglacial sediments, although the Eurasian ice sheet overrode area during LGM . These sediments were first discovered by a seismic survey and are investigated using 22.75‐m‐long core. Its upper 13.30 m comprise Holocene Lateglacial separated from lower 11.45 of hiatus. They consist highly terrigenous lacustrine which according to OSL dating, deposited an early stage last age ( MIS 5). The palynological data allow reconstruction Early Weichselian environmental history for...
Bolshaya Imandra, the northern sub‐basin of Lake was investigated by a hydro‐acoustic survey followed sediment coring down to acoustic basement. The record analysed combined physical, biogeochemical, sedimentological, granulometrical and micropalaeontological approach reconstruct regional climatic environmental history. Chronological control obtained 14 C dating, 137 Cs, Hg markers as well pollen stratigraphy revealed that succession offers first continuous spanning Lateglacial Holocene for...
Abstract. The Lena River delta, the largest delta of Arctic Ocean, differs from other deltas because it consists mainly organomineral sediments, commonly called peat, that contain a huge organic carbon reservoir. analysis sediment radiocarbon ages showed they could not have formed as peat during floodplain bogging; rather, accumulated when Laptev Sea water level was high and green mosses sedges grew were deposited on surface flooded marshes. masses layered sediments transgressive phases sea...
The new pollen record from the upper 12.75 m of a sediment core obtained in Lake Ladoga documents regional vegetation and climate changes northwestern Russia over last 13.9 cal. ka. Lateglacial chronostratigraphy is based on varve chronology, while Holocene stratigraphy AMS 14 C OSL dates, supported by comparison with records. During ( c . 13.9–11.2 ka BP ), region experienced several climatic fluctuations as reflected changes. Shrub grass communities dominated between 13.2 increase Picea at...
With its numerous environmental archives stored in lake and peat sediments relatively low human pressure, the Lake Onega region eastern Fennoscandia is regarded as a particularly promising area for studying past changes vegetation climate since Lateglacial period. The 885-cm-long sediment core RZ19 (62°27′53″N, 34°26′4″E) was collected from Razlomnoe Peat on northern shore of 2019, radiocarbon-dated analysed pollen cryptogam spores. age-depth model suggests continuous sedimentation ca....
Abstract The mid-Holocene Littorina Sea transgression has been studied in sediment cores from four coastal lakes NW Russia. basins are situated the same drainage system at elevations 6.9 to 9.2 m a.s.l. Complementary parameters have applied identify water-level changes. Chronological models based on AMS radiocarbon dating of bulk sediments but also wood remains and moss sedge peat dated a few cases. All ages calibrated calendar years BP (cal. BP). Between 8000 6000 cal. present-day were...
Two lake and bog sediments have been thoroughly studied using palynological radiocarbon dating methods. These are the Lembolovskoye Lake section located in southern part of Karelian Ithmus Mshinskoye southwestern Leningrad province. The data obtained allow us to reconstruct main features vegetation cover evolution, chronology for appearance a real distribution arboreal species from south province north, construct curves paleoclimate parameter changes area under study. Thirty-six 14 C dates...
The raised bog sediments that have been continuously accumulated over time represent the most suitable natural object which enables us to reconstruct Late Glacial and Holocene vegetation palaeoclimates. Bog peat consists of organic carbon formed in situ. It contains moss, plant fragments microfossils are necessary for study palaeovegetation palaeoclimate. However, a successful palaeoenvironment can be carried out on basis investigation great quantity samples along whole peatbog thickness. In...
Abstract The Antarctic and the surrounding Southern Ocean are currently subject to rapid environmental changes increasing anthropogenic impacts. Seabird populations often reflect those so act as indicators of variability. Their population trends may provide information on a variety parameters scale years or decades. We therefore long-term data cape petrel ( Daption capense ) from monitoring program Fildes Peninsula, South Shetland Islands, Maritime Antarctic, an area considerable human...
For understanding of the Lena River valley evolution geomorphological and geological structure in area from mouth Buotama river to Aldan (Yakutian bend) studied. Transverse profiles through valley, a map ruggedness relief density, scheme investigated were constructed. The terraces was studied, sediments dated by method optically stimulated luminescence (OSL) radiocarbon method. Spore-pollen spectra content diatom algae In we fixed low high floodplain up height 10–12 m, two terraces, which...
