近日,中国地质大学生物地质与环境地质国家重点实验室宋虎跃副研究员及合作者在国际地学领域权威期刊《GEOLOGY》上发表题目“Uranium and carbon isotopes document global-ocean redox-productivity relationships linked to cooling during the Frasnian-Famennian mass ex...
Carbon isotopes in the ocean are frequently used as paleoclimate proxies and as present-day geochemical ocean tracers. In order to allow a more direct comparison of climate model results with this ...
Following the highly publicized 1998 E1 Niño event, interest in how climatic events in the tropics affects global climate has grown. However, an understanding of the long-term natural variability...
Since the late 1990s there has been a growing impetus for a comprehensive global study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs). This has led to the development ...
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
The seasonal variability of the stable nitrogen isotope (d15N) in phytoplankton and dissolved inorganic nitrogen (DIN) in the shallow, eutrophic Lake Mikata was examined to assess the relative import...
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern Great Plains, but little is known of how the relative importance of these processes may vary...
We quantify the trophic positions of subtropical open-ocean zooplankton species using amino acid–specific (AA) stable nitrogen isotopic compositions. We model animal trophic position by computing tro...
We investigated the particulate organic matter (POM) flux and its stable carbon isotope composition in response to changes in phytoplankton primary production and abiotic environmental affects in mes...
We present a 1-yr (2005–2006) record of organic carbon (OC) and total nitrogen (TN) contents and their isotopic ratios (d13 COC and d15N) in sinking particles from the western Gulf of Lions. Maximum...
Plankton metabolic rates, such as rates of gross, net community production and community respiration, were measured in the surface waters using triple oxygen isotopes and O2 : Ar ratios. The 17 D a...
On the basis of their thermal preferences, salmon introduced in South America can distribute over the whole Southern Patagonian Shelf Ecosystem (SPSE). Stable isotope (d13C andd15N) data show that the...
To better delineate the relative contribution of shelf and slope production to the northern California Current (NCC) pelagic community, we examined the cross-shelf distribution ofd13 C in 19 species o...
To elucidate the fate of river-borne nitrate in the estuarine environment, we measured nitrate concentrations and d15N andd18O of nitrate along the salinity gradient in the estuary of the river Elbe, ...
Compound-specific nitrogen, carbon, and hydrogen isotope records from sediments of Sky Pond, an alpine lake in Rocky Mountain National Park (Colorado, United States of America), were used to evaluate ...
