近日,中国地质大学生物地质与环境地质国家重点实验室李超教授团队在国际著名地学期刊《Geology》上发表了题为“Sulfur isotope evidence for transient marine-shelf oxidation duringthe Ediacaran Shuram Excursion”的学术论文,该论文通过定量数值模拟的方法首次发现了埃迪卡拉纪碳循环剧烈扰动时期(又称“Shu...
The Sulfur Cycle     Sulfur Cycle  Earth       2015/7/22
The ocean represents a major reservoir of sulfur on Earth, with large quantities in the form of dissolved sulfate and sedimentary minerals (e.g., gypsum and pyrite). Sulfur occurs in a variety of vale...
Biogenic dimethylsulfide (DMS) and its main precursors, dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO), are potential scavengers of reactive oxygen species in marine algae, and these d...
Sulfur budgets and seasonal progression of sulfur cycling processes were investigated in Lake Fukami-ike, a small monomictic lake in Japan. The sulfur isotopic mass balance shows that the main sulfur ...

Estuarine fish may remain as residents in areas with favorable conditions for feeding and refuge, but become mobile and transient where conditions are less favorable. We developed a new approach invol...
The quotas of P, S, Mn, Fe, Ni, and Zn in individual Synechococcus cells collected from the surface and deep chlorophyll maximum (DCM) layer of three mesoscale eddies in the Sargasso Sea were measure...
We studied the seasonal variation of biotic and abiotic processes and the physico-chemical forcing factors involved in the production and consumption of dimethylsulfide (DMS) and its precursor dimethy...

Temporal and spatial variation of δ34S, total sulfur (TS) concentration, and elemental sulfur concentration (S0) in leaves, roots, and rhizomes of Zostera marina was followed between June 2002 and May...
The influence of mangrove saplings (Avicennia marina) and fiddler crabs (Uca vocans) on carbon, iron, and sulfur biogeochemistry in mangrove sediment was studied using outdoor mesocosms with and witho...
We conducted a diurnal study of gradients of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), dimethylsulfoxide (DMSO), and bacterial numbers in a stratified coastal salt pond (Sa...
In marine sediments, Fe(III) is found predominantly as a solid. Recently, however, soluble species of Fe3+ complexed by natural organic ligands have been detected in coastal marine sediments with volt...
We report continuous in situ measurements of a population of the harmful algal bloom species Cochlodinium polykrikoides in a fixed volume of inshore waters near the island of Naro-do (34.47°N and 127....
Lake Bonney is a permanently ice-covered lake in the McMurdo Dry Valleys, Antarctica. The lake has two chemically stratified lobes (referred to as the east and west lobes), each with distinct biogenic...
