This pattern was likely due to hypolimnetic phytoplankton in clearwater lakes incorporating more respired CO 2 , which is depleted in d 13 C, and subsequently passing depleted d 13 C values up the food chain. Results also showed habitat differences in d 15 N with epilimnetic and hypo...
A program (SIMULATE.BAS) has been developed in GW-BASIC to calculate the isotope patterns in the mass spectrum of ions of multinuclear organometallic clusters of the general type MNL... and of their fragments. The program has been utilized in the characterization of novel polynuclear cluster carb...
Plot of isotope counts over isotope pattern groups or components.Martin Loos
We found that the isotopic composition of precipitation follows a predictable seasonal pattern. We developed a new approach for mapping precipitation isotope seasonality that will be useful in a wide range of fields.doi:10.1029/2018GL077458Scott T. Allen...
Similar peak pattern was observed in case of the BQB-d7 labeled compounds with m/z of ([M + n × BQB-d7]n+). The mass shift of BQB and BQB-d7 labeled derivatives was always 7 Da no matter the compounds contain one or more sulfhydryl groups. To distinguish the numbers ...
to and late in the overall magmatic and hydrothermal evolution of some deposits (Figure 4(c);Bouse et al., 1999). Where this type of temporal evolution is not evident, it probably reflects a lack of distinctly different isotopic reservoirs rather than the absence of this evolutionary pattern....
