Sea level as a metronome of Earth’s history reports that researchers at the University of Geneva (UNIGE), Switzerland, — together with colleagues at the University of Lausanne (UNIL) and American and Spanish scientists — have been working on an analytical method that combines observing deep-water sedimentary strata and measuring in them the isotopic ratio between heavy and light carbon. They have discovered that the cycles that buy ventolin online inhaler punctuate these sedimentary successions are not, as one might think, due solely to the erosion of mountains that surround the basin, but are more ascribable to sea level changes. This research, which can be read in the journal Geology, paves the way for new uses of isotopic methods in exploration geology.
