Zusammenfassung |
Historical literature may constitute a valuable source of information to
reconstruct sea-level changes. Here, historical documents and geological
records have been combined to reconstruct Caspian sea-level (CSL) changes
during the last millennium. In addition to a comprehensive literature review,
new data from two short sediment cores were obtained from the south-eastern
Caspian coast to identify coastal change driven by water-level changes and to
compare the results with other geological and historical findings. The
overall results indicate a high-stand during the Little Ice Age, up to
−21 m (and extra rises due to manmade river avulsion), with a −28 m low-stand
during the Medieval Climate Anomaly, while presently the CSL stands at
−26.5 m. A comparison of the CSL curve with other lake systems and proxy
records suggests that the main sea-level oscillations are essentially paced
by solar irradiance. Although the major controller of the long-term CSL
changes is driven by climatological factors, the seismicity of the basin
creates local changes in base level. These local base-level changes should be
considered in any CSL reconstruction. |
