A new study by researchers at the Woods Hole Oceanographic Institution and Harvard University may help settle a long-standing question: how do small amounts of organic carbon become locked away in roc...
2018年1月,有关“南美洲新近系Orinoco三角洲大陆架及陆架边缘沉积演化”的研究成果刊发在美国地质学会国际重要期刊《Geological Society of America Bulletin》上。该文第一作者为中国地质大学资源学院副教授陈思博士。
我院吴加学教授与班戈大学的Tom P Rippeth 教授,将于2016年9月12日-14日在中山大学举行 “Turbulent Mixing and Sediment Transport in the Ocean”国际研讨会,请详见以下 本次研讨会的邀请信。
Lush greenery rich in Douglas fir and hemlock trees covers the Triangle Lake valley of the Oregon Coast Range. Today, however, geologists across the country are more focused on sediment samples dating...
Sediment dynamics were investigated in Lake Maggiore, Italy, with field observations from October to mid-December 2012. Three moorings were deployed in Pallanza Bay, a small embayment on the western s...
A Duke University team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could indire...
We measured nitric oxide (NO) microprofiles in relation to oxygen (O2) and all major dissolved N-species (ammonium, nitrate, nitrite, and nitrous oxide [N2O]) in a permeable, freshwater sediment (Rive...
Mechanistic models for sediment transport on hillslopes are needed for applications ranging from landscape evolution to debris-flow hazards. Progress has been made for soil-mantled landscapes; however...
The historical trend of the concentrations of carotenoids originating from phytoplankton in sediment cores collected at two sites in Lake Shinji, a eutrophic oligohaline lake was investigated to clar...
187Os/188Os ratios and osmium concentrations were analyzed in sedimentary reference materials JSd-3, JMS-1, and JMS-2, issued by the Geological Survey of Japan, using the isotope dilution method with...
Measuring sediment flux in rivers remains a significant problem in studies of landscape evolution. Recent studies suggest that observations of seismic noise near rivers can help provide such measureme...
In order to determine the distribution of sediments, bottom-withdrawal settling velocity tubes (SVTs) are used. This technique is, for example, often applied in estuaries. Yet, these tubes have serio...
In order to investigate survival of diatoms and long-term pigment dynamics in dark sediment, we incubated samples of homogenized, sieved, tidal-flat sediment for 1 yr in darkness. Microscopic observa...
In view of the requirement of a well-characterized and easily available aquatic sediment reference material, a comprehensive analysis comprising of fifty major, minor and trace elements as well as Sr-...
To assess the long-term (27 yr) effects of sediment aging on stable carbon and nitrogen isotope values (δ13C and δ15N), we used a collection of eight freeze cores of annually laminated (varved) lake s...
