Abstract Improved daily precipitation and temperature data at 5 × 5‐km grids for 1960–2015 were developed the Upper Yarkant basin (UYB) based on observations of gradients lapse rates. The climate are then used to drive VIC‐Glacier hydrological model simulate runoff process UYB. A large altitudinal dependence is observed in both temperature, with three patterns gradient elevation bands <2,000 m, 2,000–3,000 >3,000 respectively, a strong seasonal variation rate ranging from 0.4 0.8...
Abstract Black carbon (BC) is considered as an important contributor to the Himalayan glaciers melt in past few decades. However, long‐term source apportionment of BC remains unclear. Here we present first radiocarbon ( 14 C)‐based annual variation ice core spanning period 1959–2012 drilled from Southeastern Tibetan Plateau, a receptor site South Asia outflow. We find fossil fuel combustion major contribution (73% ± 5%), yet biomass burning fraction ƒ ) has grown 24% 4% 30% since 1990....
A Gram-stain-negative, aerobic, rod-shaped, motile bacterium, strain B1555-1T, was isolated from an ice core drilled Ulugh Muztagh Glacier, China. The optimum growth temperature of B1555-1T 15 °C and pH 7. major fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 1ω6c), 0 8 (C18 C18 1ω6c). predominant respiratory quinone Q-8. polar lipids phosphatidylethanolamine phosphatidylglycerol. DNA G+C content 66.0 mol%. In 16S rRNA gene sequence comparisons, affiliated to the genus Massilia...
Abstract. The Tibetan Plateau and its surroundings have recently experienced several catastrophic glacier-related disasters. It is of great scientific practical significance to establish ground-based early warning systems (EWSs) understand the processes mechanisms glacial disasters warn against potential threats downstream settlements infrastructure. However, there are few sophisticated EWSs on Plateau. With support Second Scientific Expedition Research Program (STPSER), an EWS was developed...
A psychrophilic, Gram-stain-negative, rod-shaped, red-pigmented bacterium, designated strain B1789T, was isolated from an ice core of Muztagh Glacier on the Tibetan Plateau in China. Phylogenetic analysis based 16S rRNA gene sequences showed that B1789T related to members genus Hymenobacter and had highest sequence similarity with antarcticus JCM 17217T (97.9 %). The major menaquinone MK-7 polar lipid phosphatidylethanolamine. predominant fatty acids were iso-C15 : 0, anteiso-C15 0 summed...
A bacterial strain, B5-2T, was isolated from an ice core drilled Muztagh Glacier, China. Strain B5-2T a Gram-stain-negative, short rod-shaped, motile by polar flagella, aerobic bacterium. The major fatty acids of strain were summed feature 8 (C18 : 1ω7c and/or C18 1ω6c) and iso-C13 0. G+C content the DNA 69.3 mol%. predominant isoprenoid quinone Q-10. lipids phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine,...
A Gram-stain-negative, rod-shaped, bacterial strain, B448-2T, was isolated from an ice core the Muztagh Glacier, on Tibetan Plateau. B448-2T grew optimally at pH 7.0 and 20 °C in presence of 0–1.0 % (w/v) NaCl. The results 16S rRNA gene sequence similarity analysis indicated that closely related to Massilia eurypsychrophila CGMCC 1.12828T, Rugamonas rubra CCM3730T Duganella zoogloeoides JCM20729T levels 97.8, 97.7 97.3 %, respectively. predominant fatty acids were summed feature 3 (C16 :...
Abstract Variations in the Indian Monsoon (IM) and Westerlies (WS) significantly affect climate on Tibetan Plateau (TP) have widespread ecological socioeconomic impacts whole of Asian society. So far, however, rate magnitude changes IM still remained unclear. Here we report for first time that rapidly shifted northward at end Little Ice Age (LIA). We used sediment proxies humidity moisture sources from Taro Co Lake, which is located transition zone between WS IM. Our comprehensive survey...
The dating of well-preserved Holocene moraines in the Qiangyong Valley, southern Tibetan Plateau (TP), offers great potential for reconstructing glacier extents and examining climate changes region. Guided by moraine features, this study used Geographic Information System (GIS) model tools to reconstruct paleo-glacier surfaces equilibrium line altitude (ELA) depressions three glacial stages valley. GIS-based models showed that Valley contained ice volumes 8.1 × 108, 6.2 4.6 108 m3 during...
A Gram-stain-negative, non-motile, reniform bacterial strain, B2974T, was isolated from an ice core of the Muztagh Glacier, on Tibetan Plateau, China. Strain B2974T grew optimally at pH 7.0-7.5 and 25-30 °C in presence 0-2.0 % (w/v) NaCl. 16S rRNA gene sequence similarity analysis indicated that strain closely related to Chelatococcus asaccharovorans LMG 25503T a level 97.1 %. The major quinone ubiquinone Q10. predominant fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 1ω6c) C19 0...
Glaciers on the Tibetan Plateau (TP) are reliable water sources for Asia. Continuously high-resolution and high-accuracy long-term glacier fluctuations have been examined to improve reliability of predictions regarding future TP behavior under global climate change. In this study, we analyzed physiochemical parameters in typical glaciolacustrine sediments reconstruct multidecadal activities monsoonal Qiangyong Glacier over past ~2500 years. The results show that advanced most strongly during...
Abstract. Exploring the snow depth on Mount Everest, one of most inaccessible places our planet, has long been a topic interest. Previously reported depths have inconsistent and large uncertainties. Here, we report ground-penetrating radar survey along north slope Everest in May 2022. Our measurements display gradual increasing transition slope, mean estimates at summit are 9.5±1.2 m. This updated is much deeper than previously values (0.9–3.5 m).
