“…Deeper sediments have to be excavated by a heavy drilling with gravity corer or piston corer Brendonck, De Meester, 2003), often from special rafts, or from ice; this is complicated and expensive work. But the deep lake long cores are widely used for pollen (Anderson, Lozhkin, 2015), chironomid (Porinchu, Cwynar, 2002;Nazarova et al, 2017), diatom (Laing et al, 1999;Palagushkina et al, 2017), and other types of analysis (Smirnov, 2018). For example the core from El'gygytgyn Lake provides a continuous record of pollen and diatom data since at least the Middle Pleistocene (Nowaczyk et al, 2002;Cherepanova et al, 2007;Lozhkin et al, 2007).…”

Остатки ветвистоусых ракообразных (Crustacea: Branchiopoda), в первую очередь, эфиппиумы Daphniidae, широко представлены в многолетнемерзлых отложениях Северной Голарктики. Можно ожидать, что они могут быть найдены во всех типах четвертичных отложений и во всех регионах зоны вечной мерзлоты. Остатки Cladocera могут быть использованы как источник информации об окружающей среде прошлого, климатических условиях и особенностях осадконакопления, кладоцерный анализ может широко использоваться в исследованиях по четвертичной экологии. Кроме того, покоящиеся яйца Daphnia и других ветвистоусых ракообразных могут быть хорошим источником материала для исследований ДНК и даже для выведения особей из покоящихся яиц. Эфиппиумы потенциально могут быть надежным источником количественной информации для палеоэкологических реконструкций. Однако для подобных исследований они должны изучаться специально, а не как побочный продукт палеоэнтомологических или палеоботанических работ. Мало того, необходимо приложить специальные усилия для выработки ключей для идентификации современных видов по эфиппиумам. Основная идея публикации данного сообщения-привлечь внимание сообщества ученых, изучающих четвертичный период, к эфиппиумам как новому источнику информации о прошлом водоемов.

Results of a paleolimnological investigated of a well-dated lake sediment section from Shikotan Island (Southern Kurils) showed that from ca 8.0 to 5.8 cal ka BP warm and humid period corresponding to middle Holocene optimum took place. Cooling thereafter corresponds to Neoglacial. A reconstructed from ca 0.9 to ca 0.58 cal ka BP warm period can be correlated to a Medieval Warm Period. Cooling after 0.58 cal ka BP can be correlated with the LIA. Marine regression stages were identified at ca 6.2-5.9, 5.5-5.1 and 1.07-0.36 cal ka BP. The general chronology of major climatic events of Holocene in the island is in accordance with the climate records from the North Pacific region. Revealed spatial differences in timing and magnitude of the Late Holocene climatic episodes (LIA, MWP) within region needs further investigations.

“…At 0.34 and 0.106 cal ka BP fragments of oceanic diatoms indicate tsunami events. The deposits of this interval were formed during the Little Ice Age (LIA), which was distinctly pronounced across Kuriles [1,4,5,14], on Japanese Islands [7] and in Kamchatka [9][10][11]15].…”
