КЛИМАТИЧЕСКАЯ ИЗМЕНЧИВОСТЬ В ЭПОХУ МИС‑11 (370–440 ТЫС. ЛЕТ НАЗАД) ПО ДАННЫМ ИЗОТОПНОГО СОСТАВА (δD, δ18O, δ17O) ЛЕДЯНОГО КЕРНА СТАНЦИИ ВОСТОК

Представлены результаты детальных изотопных исследований  2 тыс. образцов  ледяного керна со станции Восток, относящихся к эпохе МИС-11 (370–440 тыс. л.н.). Обсуждаются методики измерения ¹⁷O-эксцесс на лазерном  анализаторе,  а также интерпретации  изотопного состава, основанные  на совместном  анализе  трёх независимых  параметров:  δD, d-excess и ¹⁷O-excess. Реконструированы климатические  условия в окрестностях станции Восток и в месте испарения  влаги (над океаном). Полученные результаты сравниваются с опубликованными результатами по станциям Восток и Конкордия, а также с данными по морским колонкам DSDP 94-607 и ODP 177-1090.
