New research describes evidence that deep sea methane deposits change into gas more frequently than could be monitored previously and that a set of fossilized organisms has a unique ability to detect ...
Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
Eutrophication and metal pollution are global environmental problems. The risk of metal pollution is high in the eutrophic lakes because of high mobility of metal in sediments.
A day is the time for Earth to make one complete rotation on its axis, and a year is one revolution around the Sun -- reminders that basic units of time and periods on Earth are intimately linked to o...
2018年1月28日,地球物理领域知名期刊《Geophysical Research Letters》刊发了中国地质大学工程学院宁伏龙教授研究团队的研究论文:基于粉土/砂直剪测试的含水合物沉积地层力学强度评估(Strength estimation for hydrate-bearing sediments from direct shear tests of hydrate-bearing sa...
More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new Duke University study finds that high levels...
Marine gas hydrates, one of the largest methane reservoirs on Earth, may greatly affect the deep sea sedimentary environment and biogeochemistry; however, the carbon geochemistry in gas hydrate-bearin...
The mangrove of Hara Biosphere Reserve, stretching over 100 thousand hectares in the southern coast of Iran and in the northwest of Qeshm Island, belongs to the most important and largest mangroves in...
Chemical and physical properties of humic acids (HAs) isolated from Mudbanks (locally known as “Chakara”—a unique phenomenon occurring along the south west coast of India during the southwest monsoon...
Our automatic digestion device is applied in determining the quantity of organic carbon in the soils/sediments. Its operation process is simple. The reaction conditions are optimized; the complex pret...
Coenzyme F430 is the hydrocorphinoid nickel complex which acts as active site in methyl-coenzyme M reductase (MCR). The MCR-F430 complex catalyzes the last step of methanogenesis: reduction of methyl...
Sub-bottom profiling was conducted in the Japanese Exclusive Economic Zone (EEZ) around Minamitorishima Island, western Pacific Ocean, to investigate the features and distribution of mud rich in rare...
Models designed to simulate physical or mechanical phenomena associated with the seafloor often require a knowledge of or at least an ability to estimate, the physical property structure of the upper ...
The scientific ocean drilling community has been retrieving cores from hundreds of meters below the seafloor since the inception of the Deep Sea Drilling Project (DSDP) in 1968. While microbiological ...
Certain low-molecular-weight gases, such as methane, ethane, and carbon dioxide, can combine with water to form ice-like substances at high pressure or low temperature. These compounds, commonly calle...
