Signatures of rapid climatic changes in organic matter records in the western Mediterranean Sea during the last glacial period, Les variations des teneurs en carbonate, en matière organique (teneur en carbone organique, palynofaciès) et du rapport isotopique de l’oxygène des foraminifères planctoniques...

... changes in the region. The sequence of cold HS-equivalent events that repeated every 5–8 kyr in the SO over the last 350 kyr agrees with the periodicity of ice sheet break and the variations in salt content in the Greenland ices ( Heinrich, 1988 ; Mayewski et al., 1997 ). Probably, the changes...

... transfer through pathways of the short-term carbon cycle are influenced by environmental factors that operate on sub-annual to millenial scales. Except under unusual circumstances, the isotopic signature of the global marine HCO 3 − reservoir is virtually unaffected by sub-millenial variation within...

... rhythms. The high-resolution sedimentary records from Lake Baikal allow approaching the problem of the length of the last interglacial and stability of its climate in the Northern Hemisphere. The Siberian archives for the interval of 70 to 130 kyr contain brief sub-Milankovitch millenial-scale excursions...

La province de Terre-Neuve est située à proximité de la bordure de l’ancien inlandsis laurentidien et l’orientation du rivage fournit de bonnes possibilités d’étudier la variation du taux et de l’amplitude des changements du niveau de la mer...

.... TESTING THE THEORY In areas of high aridity or even drought, we would like to apply our methods and test the theory. From the wells where the water level fluctuations and/or temperature variations indicate strong tidal fluctuations, one should be able to take out water of a quantity other than calculated...

... in the Silurian on the basis of sea depth variations in different regions. East Siberia in Silurian time was occupied by a large sea, and its bottom fill has been well documented in many sections. Slow continuous deposition for 10 to 20 m. y. in peritidal environments (≤10 m) recorded in some Silurian sections...

... represent proxy records for past precipitation in low-latitude regions, which is a climate parameter that is likely to have been sensitive to variations in the GCR flux modulated by the dipole moment. Intriguingly, we observe a relatively good correlation between the high-resolution speleothem δ 18 O...

Both erosion rates (decennial and millenial) follow the same latitudinal trend, and peak where the climate is temperate (mean runoff ∼500 mm yr −1 ). Both decennial and millennial erosion rates increase nonlinearly with slope...

... melts with ≤6 wt% H 2 O and ≤0.27 wt% Cl. Our data indicate that vapor-saturated crystallization of quartz occurred at low temperatures (760–805 °C) over a wide range of pressures (50–200 MPa). For some eruptions, variations in volatiles and major and trace elements provide evidence for simultaneous...

The data confirm an atmospheric teleconnection between the ITCZ and SWW, associated with Atlantic Meridional Overturning Circulation (AMOC) variations. When the AMOC decreases, both the ITCZ and the SWW shift southward; they shift...
