Methane production and bubble emissions from arctic lakes: Isotopic implications for source pathways and ages
[1] This study reports an atmospheric methane (CH4) source term previously uncharacterized regarding strength and isotopic composition. Methane emissions from 14 Siberian lakes and 9 Alaskan lakes were characterized using stable isotopes (C and D) and radiocarbon (C) analyses. We classified ebullition (bubbling) into three categories (background, point sources, and hot spots) on the basis of fl...
متن کاملGeological, fluid inclusion and isotopic characteristics of the Gardaneshir Zn–Pb deposit, Central Iran
Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...
متن کاملMethane emissions from Amazonian Rivers and their contribution to the global methane budget.
Methane (CH4 ) fluxes from world rivers are still poorly constrained, with measurements restricted mainly to temperate climates. Additional river flux measurements, including spatio-temporal studies, are important to refine extrapolations. Here we assess the spatio-temporal variability of CH4 fluxes from the Amazon and its main tributaries, the Negro, Solimões, Madeira, Tapajós, Xingu, and Pará...
