The mudslides that follow wildfires in Southern California can be deadly -- and difficult to predict. New National Science Foundation-funded research will help officials identify areas prone to these ...
Carbon hides in sediment,keeping oxygen in atmosphere(图)     Carbon hides  sediment  keeping oxygen  atmosphere       font style='font-size:12px;'> 2019/10/28
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。
Identification of underlying geochemical processes based on samples of different types such as stream sediments, soils, and water is important for a range of applications including mineral exploratio...
Sediment buried in Oregon Coast Range points to a frosty past     Sediment buried  Oregon  Coast Range points   frosty past       font style='font-size:12px;'> 2015/12/7
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...
Nitric oxide turnover in permeable river sediment     Nitric oxide turnover  permeable river sediment       font style='font-size:12px;'> 2014/7/10
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...
Deltaic sediments of the Mekong River delta sampled from a tidal beach in Vietnam during the wet season (late October 2011) showed strong 137Cs and 134Cs activities reflecting radionuclides released ...
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...
Modern mixed alluvial-bedrock channels in mountainous areas provide natural laboratories for understanding the time scales at which coarse-grained material has been entrained and transported from thei...
Previous studies have shown that radiocesium (mainly 137Cs) was retained at the very surface of soils in Fukushima Prefecture. Clay minerals and micas are assumed as the main sorbents for cesium (Cs)...
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...
