| Zusammenfassung |
| Here we present a detailed multi-proxy record of the climate and
environmental evolution at Lake El'gygytgyn, Far East Russian Arctic during
the period 430–395 ka covering the marine isotope stage (MIS) 12/11
transition and the thermal maximum of super interglacial MIS 11c. The MIS
12/11 transition at Lake El'gygytgyn is characterized by initial warming
followed by a cold reversal implying similarities to the last deglaciation. The
thermal maximum of MIS 11c is characterized by full and remarkably stable interglacial conditions with mean temperatures of
the warmest month (MTWM) ranging between ca. 10–15 °C; annual
precipitation (PANN) ranging between ca. 300–600 mm; strong in-lake
productivity coinciding with dark coniferous forests in the catchment; annual
disintegration of the lake ice cover; and full mixis of the water column.
Such conditions persisted, according to our age model, for ca. 27 ± 8 kyr between
ca. 425–398 ka. The Lake El'gygytgyn record closely resembles
the climate pattern recorded in Lake Baikal (SE Siberia) sediments and
Antarctic ice cores, implying interhemispheric climate connectivity during
MIS 11c. |
