L'étude d'une formation bioconstruite littorale à Algues calcaires (Lithophyllum tortuosum) sur les rives d'un ilôt dans le Parc National de Port-Cros a permis de mettre en évidence des vestiges immergés qui ont été datés et indiquent que le niveau
Spectral analysis of geomorphic time series: auto-spectrum
The aim of this paper is to clarify the techniques of spectral analysis employed to determine the auto-spectrum and to examine the application and interpretation of these techniques when applied to natural time series. Throughout this paper a time
series of nearshore water level observations will be employed to demonstrate the operation and interpretation of the techniques. The techniques covered in this paper include the determination of the periodogram, auto-spectrum, and confidence intervals

In this paper, the theoretical background of spectral and cross-spectral analysis is discussed in some depth, since in the estimation of the spectrum and cross-spectrum a number of important decisions must be make for which no hare-and-fast rules

L'analyse de profils littoraux immergés, relevés par plongée, sur les côtes provençale et corse a mis en évidence des replats à profondeurs constantes entre Marseille et Port Cros. D'origine eustatique, ils sont probablement holocènes. A l'échelle
régionale, le décalage de ces replats est un indicateur néotectonique. Ainsi a été prouvée une surrection de l'ordre de 2 mètres de la région niçoise par rapport à celle de Marseille-Port-Cros. Cette méthode ne peut s'appliquer qu'aux côtes rocheuses
The two-dimensional smoothed power spectrum of the gravity field indicates that the cut-off frequency should be somewhere between 0.01 per km and 0.02 per km or the cut-off wavelength between 50 km and 100 km. Three examples from the set of regional
Bogs and lacustrine deposits are the best traps for pollens. But the identification at the level species is impossible and the pollen spectrum is never the exact reflect of the contemporaneous vegetation.

, Indian Ocean, and America during the transition from the last Interstade to the Last Glacial Maximum, from the Last Glacial Maximum to megathermal period in Holocene and the transition of the Little Ice Age by the methods of Singular Spectrum Analysis
and Maximum Entropy Spectrum. The results showed that environmental changes in the Arctic are most similar to that in the North American.
In Fujian province, the change in crop spectrum and land use by urbanization has resulted in 2 extreme trends in topsoil : nutrient depletion in grain-dominated regions and nutrient overloads in city suburbs. The rapid changes in land use and crop
spectrum caused by urbanization therefore created a challenge to the traditional soil nutrient management derived mainly from paddy fields and an urgent need for new management schemes in the province. The study provides valuable insights into nutrient
Statistical relations between the monthly rainfall amounts for 290 stations in the tropics and subtropics (30S-35N) are investigated by means of autocorrelation, power-spectrum, band-pass-filter, cross-correlation, cross-spectrum, and coherence
