Abstract The isotopic compositions of total organic carbon (TOC) in lakes have been widely used to interpret paleoclimatic changes and the depositional environments of lake sediments. However, the main factors that affect the carbon isotopes of TOC (source of organic material, water condition and others) may vary in different lake sediment records ...

Diversity of actinobacteria in sediments of Qaidam Lake and Qinghai Lake, China
Archives of Microbiology, 2021Using 16S rRNA gene analysis and high-throughput, the diversity and community structure of actinobacteria in the sediments of Qaidam Lake and Qinghai Lake with different salinity and alkalinity in Qinghai-Xizang Plateau were studied, and the differences of actinobacteria community structure and their relationship with environmental factors were ...

Modern Sedimentary Systems of Qinghai Lake
2021Studies of modern lake sedimentary systems can guide the research and understanding of ancient lake basins. Qinghai Lake formed in the Miocene is the largest inland-faulted brackish lake in China with different types of terrigenous clastic sediments distributed around the lake and is an ideal location to study modern lake sedimentary systems ...

Cryptosporidium and Giardia are important intestinal zoonotic pathogens that can infect various hosts and cause diarrhoeal diseases. There are few reports of the epidemiological prevalence and molecular characterization of Cryptosporidium and Giardia in wild birds around Qinghai Lake and in the surrounding areas on the Qinghai-Tibetan Plateau ...

Sources and distribution of microplastics in China's largest inland lake – Qinghai Lake
Environmental Pollution, 2018Microplastic pollution was studied in China's largest inland lake - Qinghai Lake in this work. Microplastics were detected with abundance varies from 0.05 × 105 to 7.58 × 105 items km-2 in the lake surface water, 0.03 × 105 to 0.31 × 105 items km-2 in the inflowing rivers, 50 to 1292 items m-2 in the lakeshore sediment, and 2 to 15 items per individual

Lacustrine beach ridges are often used to reconstruct past lake levels. However, the sedimentary architecture involved in their sedimentary evolution remains unclear, particularly for embayed beaches. To better understand the sedimentary processes, the sedimentary architecture and geomorphology of an embayed beach on the southern of Qinghai Lake were ...

Inversion and validation of QingHai Lake temperature
SPIE Proceedings, 2008Making the best of the similarity and difference of Terra and Aqua satellites, the table for searching radiant temperature is established. The radiant temperature of Terra and Aqua are imitated. It's a fact that observing angle, solar zenith angle and water column of atmosphere affect radiant temperature and the transmission, and the affection is also ...
