متن کاملThe puri®cation of chlorins from marine particles and sediments for nitrogen and carbon isotopic analysis
Methods are presented for the separation of chlorins from marine particles and sediments for nitrogen and carbon isotopic analysis. Carbon and nitrogen purities of 91 and 96%, respectively, were obtained for particulate chlorins, with recoveries of 88%. Sedimentary chlorins were obtained with carbon and nitrogen purities of 88 and 89%, respectively, and recoveries of 18%. The reproducibility of...
متن کاملMolecular and isotopic analysis of anaerobic methane- oxidizing communities in marine sediments
Convergent lines of molecular, carbon-isotopic, and phylogenetic evidence have previously indicated (Hinrichs, K.U., Hayes, J.M., Sylva, S.P., Brewer, P.G., DeLong, E.F., 1999. Methane-consuming archaebacteria in marine sediments. Nature 398, 802±805.) that archaea are involved in the anaerobic oxidation of methane in sediments from the Eel River Basin, oshore northern California. Now, further...
متن کاملLithium Isotopic Analyses of Chondrites and Chondrules
Introduction: Light stable isotopes provide insights and constraints on nebular and parent body processes. Lithium isotope studies of chondrites offer such potential, with some specifically unique aspects. Lithium is monovalent, the lightest of nongaseous elements, it has a 15% mass difference between its 2 isotopes (Li and Li), it is fluid mobile, and it is one of the fastest diffusing element...
متن کاملIsotopic composition of stratospheric ozone
Using recently measured rates for isotopic variants of the ozone formation reaction , we derive expressions for the enrichment of symmetric and asymmetric and in stratospheric ozone and calculate total enrichments of 123‰ and 107‰ for and , respectively. We compare the calculations with measurements made with the Smithsonian Astrophysical Observatory far-infrared spectrometer during seven ballo...
