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 model of the Community Earth System Model (CESM1)
ocean model Community Earth System Model
2015/8/11
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...
GEOTRACES—A Global Study of the Marine Biogeochemical Cycles of Trace Elements and Their Isotopes
Marine Biogeochemical Cycles Trace Elements Their Isotopes
2015/7/28
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 ...
Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
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 ...
Using stable nitrogen isotopes to evaluate the relative importance of external and internal nitrogen loadings on phytoplankton production in a shallow eutrophic lake (Lake Mikata, Japan)
a shallow eutrophic lake phytoplankton production
2014/4/2
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...
Spatial and temporal variability of prairie lake hydrology as revealed using stable isotopes of hydrogen and oxygen
Spatial temporal variability hydrogen and oxygen
2014/4/17
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...
Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes
zooplankton trophic position North Pacific Subtropical Gyre
2014/4/17
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...
Controls on the seasonal and interannual dynamics of organic matter stable carbon isotopes in mesotrophic Lake Holzmaar, Germany
interannual dynamics mesotrophic Lake Holzmaar Germany
2014/4/17
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...
Across margin export of organic matter by cascading events traced by stable isotopes, northwestern Mediterranean Sea

2014/4/17
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...
Spatial variations in time-integrated plankton metabolic rates in Sagami Bay using triple oxygen isotopes and O2 : Ar ratios
Spatial variations plankton metabolic rates
2014/4/21
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

Trophic relationships of exotic anadromous salmonids in the southern Patagonian Shelf as inferred from stable isotopes
Trophic relationships exotic anadromous salmonids the southern Patagonian Shelf inferred stable isotopes
2014/4/21
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...
Carbon stable isotopes reveal relative contribution of shelf-slope production to the northern California Current pelagic community
Carbon stable isotopes shelf-slope production the northern California Current pelagic community
2014/4/18
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...
A nitrate sink in estuaries? An assessment by means of stable nitrate isotopes in the Elbe estuary
