Heterogeneous environmental controls on permafrost region soil organic carbon stocks can now be quantified with spatial modeling.
Abstract Uncertainty about the geological processes that deposited syngenetically frozen ice‐rich silt ( yedoma ) across hundreds of thousands square kilometres in central and northern Siberia fundamentally limits our understanding Pleistocene geology palaeoecology western Beringia, sedimentary led to sequestration Pg carbon within permafrost whether provides a globally significant record ice‐age atmospheric conditions or just regional floodplain activity. Here, we test hypotheses aeolian...
Abstract A megaslump at Batagaika, in northern Yakutia, exposes a remarkable stratigraphic sequence of permafrost deposits ~50–80 m thick. To determine their potential for answering key questions about Quaternary environmental and climatic change northeast Siberia, we carried out reconnaissance study cryostratigraphy paleoecology, supported by four rangefinder 14 C ages. The includes two ice complexes separated unit fine sand containing narrow syngenetic wedges multiple paleosols. Overall,...
Monitoring of active layer thawing depth and thickness (ALT), using mechanical pronging continuous temperature data logging, has been undertaken under the Circumpolar Active Layer – South (CALM-S) program at a range sites across Antarctica. The objective this study was to summarize key from in different Antarctic regions 2006 2015 review state Antarctica effectiveness CALM-S program. 16 involving 8 another boreholes have used study. Probing for thaw depth, while giving information on local...
This study summarizes seasonal thawing data collected in different permafrost regions of northeast Asia over the 1995–2018 period. Empirical observations were undertaken under Circumpolar Active Layer Monitoring (CALM) program at a range sites across landscapes Yana-Indigirka and Kolyma lowlands Chukotka Peninsula, supplemented with 10 years from volcanic mountainous areas Kamchatka Peninsula. Thaw depth observations, taken using mechanical probing end season, ground temperature...
Abstract The paleopedology of the world’s largest retrogressive thaw slump, Batagay, is understudied. Micromorphological and geochemical analysis reveal properties th host sediments major pedogenic features. Epigenetic soil profiles Marine Oxygen Isotope Stage (MIS) 7 (or older) 5e are clearly distinguished well developed due to favorable bioclimatic conditions for pedogenesis, probably similar modern ones. oldest unit contains a paleosol Histic Reductaquic Cryosol, indicating peat-covered,...
Trace element concentrations were studied in soils of the King George and Elephant islands maritime part West Antarctica. The lowest Cu, Pb, Cd, Zn, Ni Mn typical for pristine soil Island. highest these elements found Fildes Peninsula revealed influence human activities area Bellingshausen station adjacent waste disposal sites. Ornithogenic have shown low Cd As. Using geoaccumulation indexes, all ornithogenic classified as unpolluted; human-affected mainly identified moderately polluted....
Soil organic matter (SOM) was studied in different types of organo-mineral material (from surface horizons and partially isolated materials—cryoturbated or buried horizons) sampled from the horizons, central parts Cryosol profiles, lower active layer. We found that humic acids (HAs) cryoturbated showed an increased degree oxidation increment alkylaromatic protonized aromatic fraction content. In contrast, HAs values alkylic carbon components. The content free radicals essentially higher...
Изучены строение и свойства отложений крупнейшей регрессивной термоденудационной котловины Батагай. Стратиграфическая последовательность многолетнемерзлых предположительно непрерывно накоплена за период среднего-позднего неоплейстоцена (~700-11 тыс. лет назад) частично трансформирована в течение голоцена. На основе палеопочвенных, палеонтологических геокриологических данных получены новые представления об историческом развитии почвенно-растительного покрова позднеледниковой фауны Янского...
