The distribution of branched glycerol dialkyl tetraethers (brGDGTs) in soils, peats, and lake sediments has been shown to correlate with mean annual air temperature (MAAT) provided valuable new climate reconstructions. Here we use an improved chromatographic method quantify the fractional abundances 5- 6-methyl isomers surface from 65 East African lakes spanning temperatures 1.6–26.8 °C, investigate relationships between these temperature, pH, other environmental variables. We find that...
The concept of high-quality development has become the current theme China’s economic construction. High-quality requires maintaining a healthy and cyclical approach to development, which is challenge in original approach. Yet, great deal evidence suggests that there strong interrelationship between ecological environment, developing method quantify this important for studying extent development. Here, we propose new indicator system using coupling degree model coordination assess coupled...
Remotely sensed images with low resolution can be effectively used for the large-area monitoring of vegetation restoration, but are unsuitable accurate small-area monitoring. This limits researchers’ ability to study composition species and biodiversity ecosystem functions after ecological restoration. Therefore, this uses LiDAR hyperspectral data, develops a hierarchical classification method classifying based on technology, decision tree random forest classifier, applies it eastern waste...
Abstract Branched glycerol dialkyl tetraethers (brGDGTs) from lacustrine sediments have been widely used to reconstruct mean annual air temperature (MAAT). Although many proxy calibrations relating brGDGT characteristics put forth, these may produce warm biases when applied lakes in cold regions. We present an expanded Chinese lake surface sediment brGDGT‐MAAT calibration with 29 new samples regions along 39 previously published lakes. deployed traps a meromictic lake, Dagze Co, and compared...
A Bottom Simulating Reflector (BSR) is a seismic feature closely related to marine gas hydrate as it usually regarded the response of base stability zone in profiles. BSRs are widely distributed Makran accretionary wedge, and double observed at some locations. Double appear on profiles two layers located distinct depths but with large lateral amplitude variations. Based multi-channel reflection data acquired over this work studies origin BSR wedge its association fluid escape events. Our...
Abstract A method for diagnosing implosion symmetry in inertial confinement fusion(ICF) with wide-angle velocity interferometer system any reflector(VISAR)was proposed this study. The considers the object-image relationship of VISAR, characteristics fringe pattern, and theory; pattern must be continuous space to apply method. Hydrodynamic calculations showed that radiation-temperature distribution on surface capsule was spatially continuous, indirectly proving applicability evolution P2...
A set of organic-rich black shales has developed in the lower Gaojiabian Formation (Lower Silurian) Lower Yangtze region, South China. However, limited research on its paleoenvironment and mechanisms organic matter enrichment hindered further analysis shale gas exploration prospects this area. Utilizing samples from Akidograptus ascensus to Cystograptus vesiculosus graptolite biozones obtained well SY-1, we analyzed geochemical elements pyrite framboids reconstruct paleoenvironmental...
Bacterial lipid branched glycerol dialkyl tetraethers (brGDGTs) are a valuable tool for reconstructing past temperatures. However, gap remains regarding the influence of bacterial communities on brGDGT profiles. Here, we identified two distinct patterns brGDGTs from surface sediments 38 Tibetan Plateau lakes using an unsupervised clustering technique. Further investigation revealed that salinity and pH significantly change community composition, affecting profiles causing brGDGT-based...
It is currently suggested that climate change on the northeastern Tibetan Plateau (TP) was influenced alternately by monsoon and Westerlies. However, mechanisms driving Holocene TP remain unclear, since extent of influence individual atmospheric circulation systems has not yet been clearly defined because shortage high-quality paleoclimatic records. This especially true in central TP, where only a few ice core paleolimnological records are available. Here, we present decadal-resolution...
Abstract Ratios of glycerol dialkyl tetraethers (GDGT), which are membrane lipids bacteria and archaea, at the base several paleoenvironmental proxies. They frequently applied to soils as well lake‐ marine sediments generate records past temperature soil pH. To derive meaningful environmental information from these reconstructions, high analytical reproducibility is required. Based on submitted results by 39 laboratories across world, employ a diverse range quantification methods, we...
The Tibetan Plateau (TP) has numerous glaciers that provide water for more than one-third of the world's population. Reconstructing past temperature change on TP provides a valuable context assessing current and possible future status glaciers. However, quantitative paleotemperature records since last deglaciation are sparse. Moreover, existing have revealed conflicting Holocene variation patterns northeastern western TP. Quantitative central would be essential better understanding...
