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...
Transformation and fate of microphytobenthos carbon in subtropical shallow subtidal sands: A 13C-labeling study
Transformation fate of microphytobenthos carbon subtropical shallow subtidal sands A 13C-labeling study
2014/4/2
Microphytobenthos (MPB) in photic sediments are highly productive but the fate of this production remains uncertain. Over 33 d, tracing of 13C from added bicarbonate in subtropical shallow subtidal sa...
对鄂霍次克海东南部OS03-1岩芯180 ka BP以来底栖有孔虫内生种Uvigerina spp.进行了稳定氧碳同位素分析，发现了112~109 ka BP（Ⅵ），102~90 ka BP（Ⅴ），85~76 ka BP（Ⅳ），57~54 ka BP（Ⅲ），44~40 ka BP（Ⅱ）和17~10 ka BP（Ⅰ）的6次δ13C轻值事件，其中发生于102~90 ka BP的轻值事件Ⅴ中的δ13C降...

Cyanobacteria as a carbon source for zooplankton in eutrophic Lake Taihu, China, measured by 13C labeling and fatty acid biomarkers
Cyanobacteria carbon source zooplankton eutrophic Lake Taihu China measured by 13C labeling fatty acid biomarkers
2014/4/4
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...
δ13C is a signature of light availability and photosynthesis in seagrass
δ13C signature of light availability photosynthesis in seagrass
2014/4/4
We explored the role of light-saturated (carbon-limited) photosynthesis on δ13C of turtlegrass (Thalassia testudinum Banks ex König) populations from the clear, blue waters of the Great Bahama Ba...
晚更新世以来, 源自南大洋深层水对流的冰消期δ13C 低值事件广泛记录于低纬热带和南半球大洋沉积物中. 然而, 末次冰消期δ13C 宽幅低值事件也出现在远至北半球中纬度的西北太平洋边缘海区. 在西北太平洋的古海洋记录中, 受来自北半球高纬度地区影响的记录很多, 而来自南半球高纬度地区的却很少. 黑潮源区连接着西北太平洋与热带-南太平洋, 该区MD06-3054 孔高分辨率的浮游有孔虫记录有助于探明...

Fate of peptidoglycan in an intertidal sediment: An in situ 13C-labeling study
an intertidal sediment An in situ 13C-labeling study
2014/5/4
We investigated the fate of peptidoglycan, a bacterial cell wall component, in sediment by 13C-labeling the bacterial community of an intertidal mudflat and subsequently tracing the fate of 13CC in D-...
Extreme 13C enrichments in a shallow hypereutrophic lake: Implications for carbon cycling
Extreme 13C enrichment shallow hypereutrophic lake carbon cycling
2014/5/19
An analysis of stable carbon isotope (δ13C) ratios in Lake Apopka, Florida, reveals extreme 13C enrichments of dissolved inorganic carbon (DIC) pools in the water column and sediment pore water of thi...
Carbon-nitrogen coupling and algal-bacterial interactions during an experimental bloom: Modeling a 13C tracer experiment
Carbon-nitrogen coupling algal-bacterial interactions experimental bloom 13C tracer experiment
2014/5/14
We tracked flows of carbon and nitrogen during an experimental phytoplankton bloom in a natural estuarine assemblage in Randers Fjord, Denmark. We used 13C-labeled dissolved inorganic carbon to trace ...
Autochthonous versus allochthonous carbon sources to bacteria: Results from whole-lake 13C addition experiments
Autochthonous allochthonous carbon sources bacteria whole-lake 13C
2014/5/14
Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column. DOC is a heterogeneous mixture of molecules, some of which are imported from the watershed ...
Upwelling and the condition and diet of juvenile rockfish: A study using 14C, 13C, and 15N natural abundances

Juvenile Sebastes jordani individuals sampled in late spring 1995, 1996, and 1997 near Monterey Bay, California, were analyzed for Δ14C, δ13C, and δ15N. As anticipated, a strong negative correlation w...
Carbon dioxide partial pressure and 13C content of north temperate and boreal lakes at spring ice melt
Carbon dioxide partial pressure 13C content north temperate boreal lakes spring ice melt
2014/6/9
Carbon dioxide (CO2) accumulates under lake ice in winter and degasses to the atmosphere after ice melt. This large springtime CO2 pulse is not typically considered in surface-atmosphere flux estimate...
