Natural gas hydrates have been hailed as a new and promising unconventional alternative energy, especially fossil fuels approach depletion, energy consumption soars, fuel prices rise, owing to their extensive distribution, abundance, high efficiency. Gas hydrate reservoirs are similar storage cupboard in the global carbon cycle, containing most of world's methane accounting for third Earth's mobile organic carbon. We investigated stability zone burial depths from viewpoint conditions...
Submarine cold seeps and hydrothermal vents are the key agents of material energy exchange between marine lithosphere outer geospheres. Moreover, they breed natural gas hydrates, massive metal sulfides, precious genetic resources one main targets modern scientific research resource exploration. A series systems developed in Okinawa Trough (OT), a typical back-arc basin western Pacific. Due to their geographical proximity, two extreme environments have evident mutual or influence on...
Abstract The cause of massive blooms Ethmodiscus rex laminated diatom mats (LDMs) in the eastern Philippine Sea (EPS) during Last Glacial Maximum (LGM) remains uncertain. In order to better understand mechanism formation E . LDMs from perspective dissolved silicon (DSi) utilization, we determined isotopic composition single frustules (δ 30 Si ) two sediment cores Parece Vela Basin EPS. study cores, δ varies −1.23‰ −0.83‰ (average −1.04‰), a range that is atypical marine and corresponds lower...
Abstract Iron (Fe), sulfur (S), and molybdenum (Mo) geochemistry in marine sediments impacted by hydrothermal plumes and/or cold seeps is complex has not been systematically documented. Here we characterize Fe, S, Mo diagenesis between the Minami‐Ensei Knoll field a cold‐seep site of middle Okinawa Trough. Results show that distances away from steep trough slope may significantly affect transport Fe. The transformation reactive Fe to poorly or unreactive Fe‐bearing phyllosilicates decreased...
The Okinawa Trough (OT) is a back-arc basin with wide distribution of active cold seep systems. However, our understanding the metabolic function microbial communities in sediments OT remains limited. In this study, we investigated vertical profiles functional genes involved methane, nitrogen, and sulphur cycling OT. Furthermore, explored possible coupling mechanisms between these biogeochemical cycles. study revealed that majority associated nitrogen cycles were most abundant surface...
Active cold seeps in the Okinawa Trough (OT) have been widely identified, but sediment microbial communities associated with these sites are still poorly understood. Here, we investigated distribution and biomass of communities, particularly those anaerobic oxidation methane (AOM), sediments from an active seep mid-Okinawa Trough. Methane-oxidizing archaea, including ANME-1a, ANME-1b, ANME-2a/b, ANME-2c, ANME-3, were detected OT sediments. Vertical stratification methanotrophic archaea...
Widespread seepage of methane from seafloor sediments on continental margins may plays an important role in cycles the ocean and even atmosphere. However, distribution pattern has not been fully understood. To assess characteristics its influence atmosphere, we report emissions shelf west slope middle back-arc Okinawa Trough (OT), East China Sea. The result shows that concentrations are obviously heterogeneity. highest value, which is more than 10 times background concentration, presented...
Understanding the modern marine methane processes, which can profoundly affect global climate and have far-reaching impacts on human living environments, is critical for research carbon cycle. Thus, modeling of processes has attracted increasing attention due to models accurately simulate predict environmental effects atmospheric ecosystems. In this study, we review applications works including methanogenesis in sediments, transport reaction sediments seawater, emissions atmosphere. Compiled...
The East Asian Monsoon (EAM) is a regional factor affecting the climate and oceanographic processes of marginal seas along Western Pacific. Finding proxies for EAM intensity reconstructing interannual interdecadal variations using high-resolution records are necessary to improve our understanding EAM’s role in global system predicting change. In this paper, sedimentary core C0702 obtained from inner continental shelf China Sea were comprehensively analyzed laser particle size analyzer, an...
