Thermokarst lakes, serving as significant sources of methane (CH4), play a crucial role in affecting the feedback of permafrost carbon cycle to global warming. However, accurately assessing CH4 emissions from these lakes remains challenging due to limited observations during lake ice melting periods. In this study, by integrating field surveys with...
Precipitation variation profoundly affects agricultural development and increases the diffuse pollution risk, which may weaken the positive effects of pesticide reduction policy. This study aimed to analyze the response of pesticide discharge loads in the large vulnerable watershed to pesticide application intensity and precipitation variance befor...
The magnitudes of annual CO 2 and CH 4 emissions from thermokarst lakes and ponds are uncertain due to scarce measurements on the Tibetan Plateau (TP) and limited data on emissions during ice-melt. To evaluate the importance of CO 2 and CH 4 emissions during late winter and spring among the whole year, surface water CO 2 and CH 4 concentrations wer...
Carbon dioxide (CO2) and methane (CH4) emissions from freshwater ecosystems are predicted to increase under climate warming. However, freshwater ecosystems in glacierized regions differ critically from those in non-glacierized regions. The potential emissions of CO2 and CH4 from glacierized environments in the Tibetan Plateau (TP) were only recentl...
The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface of the Earth are powerful tools for tracing dust sources and sinks on the Earth's surface. To differentiate between the spatial variabilities in eolian dust sources in key cryospheric regions at the three poles (the Arctic; Antarctica; and the “third pole”, cove...
Evasion of greenhouse gases (GHG) from fluvial systems is now recognized as a significant component of the global carbon cycle. However, the magnitudes of GHG fluxes remain uncertain due to limited research data, especially on the Tibetan Plateau. In this study Methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O) concentrations were measure...
Highlights
The co-occurrence network structure of bacteria was more diverse and complex in sediment than in water, while archaea showed an opposite trend at environment under ice.
Microbial diversity increased in MS and SH points, and microbial community composition and microbial network complexity were also different among four points.
The divers...
The increased fraction of first year ice (FYI) at the expense of old ice (second-year ice (SYI) and multi-year ice (MYI)) likely affects the permeability of the Arctic ice cover. This in turn influences the pathways of gases circulating therein and the exchange at interfaces with the atmosphere and ocean. We present sea ice temperature and salinity...
The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface of the Earth are powerful tools for tracing dust sources and sinks on Earth’s surface. To differentiate between the spatial variabilities of aeolian dust sources in key cryospheric regions at the three poles (including the ‘Third Pole’ covering the high mountain...
Sedimentary soil organic carbon (SOC) stored in thermokarst lakes and ponds (hereafter referred to as thaw lakes) across high-latitude/altitude permafrost areas is of global significance due to increasing thaw lake numbers and their high C vulnerability under climate warming. However, to date, little is known about the SOC storage in these lakes, w...
Arctic Ocean properties and processes are highly relevant to the regional and global coupled climate system, yet still scarcely observed, especially in winter. Team OCEAN conducted a full year of physical oceanography observations as part of the Multidisciplinary drifting Observatory for the Study of the Arctic Climate (MOSAiC), a drift with the Ar...
Inland waters are important sources of greenhouse gases (GHGs) to the atmosphere that may partially offset the terrestrial carbon sink. However, GHG emissions from high altitude saline lakes on the Tibetan Plateau are currently poorly constrained. In this study, we measured methane (CH4) and carbon dioxide (CO2) concentrations and their carbon stab...
IPCC第六次评估报告（AR6）第一工作组报告对气候系统各要素的可预测性（predictability）、不可逆性（irreversibility）和深度不确定性（deep uncertainty）给出了新认识。文中基于此对全球冰冻圈变化的上述三方面加以总结和归纳。总体来看，无论何种排放情景，半球和全球尺度上冰冻圈各要素于21世纪均具有一定的可预测性，即均向融化或退化方向变化，且具有不可逆性；但在区域尺度、短时间尺度和百年以上时间尺度上，不同冰冻圈要素或因内部变率大、或因响应机制复杂而存在可逆、可预测性差乃至深度不确定性难题。
The IPCC AR6 Working Group I gives new understandings of the predictability, irrev...
With global warming, glaciers in the high mountains of China are retreating rapidly. However, few data have been reported on whether greenhouse gases from these glaciers are released into the atmosphere or absorbed by glacial meltwater. In this study, we collected meltwater and ice samples from Laohugou Glacier No. 12 in western China and measured...
Thermokarst lakes and ponds (hereafter referred to as thaw lakes) play an important role in the permafrost regions by regulating hydrology, ecology, and biogeochemistry. However, detailed quantitative information on thaw lake extent and distribution remains poorly resolved across the entire permafrost regions on the Qinghai‐Tibet Plateau (QTP). Her...
Ebullition has been shown to be an important pathway for methane (CH4) emissions from inland waters. However, the CH4 fluxes and their magnitudes in thermokarst lakes remain unclear due to limited research data, especially on the Tibetan Plateau (TP). The magnitude and regulation of two CH4 pathways, ebullition and diffusion, were investigated in 3...
