Cyclic population dynamics are of central interest in ecology. Reliably identifying and quantifying the cyclicity of populations is valuable for the understanding of regulatory mechanisms and their variability across spatiotemporal scales. Cyclicity can be detected using periodogram analysis of time series. ...
Lacustrine sedimentation is very sensitive to climate changes and its cyclicity analysis allows a better quantitation of the time of sedimentation than other methods. Climate and tectonic influence on sedimentation in a synrift basin is interpreted from the spectral analysis of a 49-m-thick series, ...
The Opalinus Clay, a silty to sandy claystone formation, Early to Middle Jurassic (Toarcian and Aalenian) in age, has been selected as the host rock for deep subsurface disposal of radioactive waste in Switzerland. Over the past thirty years, numerous geotechnical, mineralogical, and sedimentologi...
The periodicities detected in the Cismon time series fall in the range of Milankovitch cycles. Cycle periods of 45cm, 80cm and 180cm likely correspond to dominant precession, obliquity and eccentricity cycles. Owing to the inaccuracy of the Cretaceous time scale, periods cannot be matched exactly...
Cyclical patterns in volcanic degassing revealed by SO_2 flux timeseries analysis: An application to Soufrière Hills Volcano, Montserrat Cyclical patterns of behaviour in timeseries of seismic and geodetic data at volcanoes are frequently observed during lava dome-building eruptions, and are...

STUDY ON SEQUENCE STRATIGRAPHY OF THE DESERT SYSTEM:EXAMPLE FROM THE LOWER SERIES OF CRETACEOUS IN THE KUCHE BASIN IN XINJIANG The Cretaceous strata in the Kuche Basin in Xinjiang are marked by a set of arid red beds,which belong to the lower series of Cretaceous. Several types of ... M ...
Time series analysis of magnetic susceptibility variations in deep marine sedimentary rocks: A test using the upper Danian–Lower Selandian proposed GSSP, ... (MS) data can potentially provide a measure of climate variability and thus become a proxy characterizing climate cyclicity in a wide range...

To identify these effects and their modes of variability in radon progeny time series, we have applied singular spectrum analysis (SSA). We analyzed hourly measurements of radon progeny for a 6-month period acquired from a 10-m-deep borehole at the Multi-Parametric Geophysical Observatory at G...
