Zusammenfassung |
Lying at the transition between the temperate Mediterranean domain and
subtropical deserts, the Levant is a key area to study the palaeoclimatic
response over glacial–interglacial cycles. This paper presents a precisely
dated last interglacial (MIS 5) stalagmite (129–84 ka) from the Kanaan
Cave, Lebanon. Variations in growth rate and isotopic records indicate a
warm humid phase at the onset of the last interglacial at ~ 129 ka that lasted until ~ 125 ka. A gradual shift in speleothem
isotopic composition (125–122 ka) is driven mainly by the δ18O
source effect of the eastern Mediterranean surface waters during sapropel 5 (S5). The onset of glacial inception began after ~ 122 ka,
interrupted by a short wet pulse during the sapropel 4 (S4) event. Low growth rates and
enriched oxygen and carbon values until ~ 84 ka indicate a
transition to drier conditions during Northern Hemisphere glaciation. |
