Flexible Soil Microbial Carbon Metabolism Across an Asian Elevation Gradient
The function and change of global soil carbon (C) reserves in natural ecosystems are key regulators of future carbon-climate coupling. Microbes play a critical role in soil carbon cycling and yet there is poor understanding of their roles and C metabolism flexibility in many ecosystems. We wanted to determine whether vegetation type and climate zone influence soil microbial community composition (fungi and bacteria) and carbon resource preference…
Seasonal 14 C and Sr/Ca Records of a Modern Coral around Daya Bay Nuclear Power Plants
Due to an increasing number of nuclear reactors in operation, the radiocarbon ( 14 C) released from nuclear power plants (NPPs) has become an important anthropogenic source of 14 C. The examination of seasonal Δ 14 C and monthly Sr/Ca, Mg/Ca variations in a coral in Daya Bay (China) shows that NPPs located there have an impact on the Δ 14 C level and sea surface temperature (SST). The Mg/Ca variation was in good correlation with the Pacific Decad…
Fossil-Fuel-Derived CO 2 Contribution to the Urban Atmosphere in Guangzhou, South China, Estimated by 14 CO 2 Observation, 2010–2011
From October 2010 to November 2011, the urban atmospheric CO 2 concentration in Guangzhou ranged from 550 to 460 ppm, with mean monthly concentration fluctuating between 530 and 470 ppm. A lower concentration was observed in summer and autumn, while a higher concentration occurred in spring and winter. The urban atmospheric CO 2 δ 13 C value varied between −9.00 and −13.10%, with mean monthly value fluctuating between −9.60 and −11.80%. There was…
C and 10Be of the dust fall and loess profile in the north China since Holocene
Distribution of 14 C and 13 C in Forest Soils of the Dinghushan Biosphere Reserve
We report here first results on the bulk soil organic carbon (SOC), apparent radiocarbon ages and δ 13 C characteristics of the tropical and subtropical forest soil in Dinghushan Biosphere Reserve (DHSBR). The forest oxisol in Dinghushan has developed during the Holocene. The δ 13 C variation curves in all three profiles may be divided into two sections. The upper section from 0 to 40 cm has δ 13 C values varying from −27.4 to −24.1‰, −27.5 to −2…
C Dating of Terrestrial Moss in Tern Lake Deposits, Antarctica
Accurate radiocarbon ages were obtained from terrestrial moss from two drill holes in Tern Lake deposits, Antarctica, using liquid scintillation counting (LSC) and accelerator mass spectrometry (AMS). The results show that the lake deposits have been accumulating since the end of the last glacial epoch ca. 12,600 cal BP at the rate of 0.13–1.1 mm a -1 . We discuss the validity of 14 C ages of Antarctic lake deposits, with respect to the latitude …
