With the onset of warming, the sea level began to rise rapidly, flooding the coastal plain. To date, the course of the postglacial sea-level rise has already been gradually reconstructed. We know when the flooding began, how and at what speed the sea rised, where the bulk of the sediments accumulated, and when the transgression stopped. But what was happening in the water column at that time? What water masses prevailed on the shelf, how did the river mouths move southward, what were the temperature and salinity of the surface waters? Has North Atlantic water got to the shelf? Microscopic planktonic organisms that lived at that time and were buried in the bottom sediments of the shelf can tell us about this. Our results of studies of the microalgae complexes in four sediment cores from the shelf and continental slope help to reconstruct the environmental history of the Laptev Sea for the last 17.5 cal. ka.</p></abstract><trans-abstract xml:lang="ru"><p>Во время максимума последнего оледенения на месте современного моря Лаптевых была суша, а берег отступил на сотни километров к северу. С началом потепления уровень моря стал стремительно повышаться, затапливая прибрежную равнину. К настоящему времени ход голоценовой трансгрессии уже поэтапно реконструирован. Нам известно, когда началось затопление, как и с какой скоростью наступало море, где скапливалась основная масса осадков и когда трансгрессия прекратилась. Но что происходило в то время в толще воды? Какие водные массы господствовали на шельфе, как смещались к югу речные устья, каковы были температура и соленость поверхностных вод? Попадала ли сюда, как сегодня, вода из Северной Атлантики? Обо всем этом нам могут рассказать микроскопические планктонные организмы, жившие в то время и сохранившиеся в донных осадках шельфа. По результатам изучения комплексов микроводорослей в четырех грунтовых колонках, полученных с шельфа и континентального склона, реконструирована история моря Лаптевых за последние 17.5 тыс. лет.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Arctic</kwd><kwd>Laptev Sea</kwd><kwd>transgression</kwd><kwd>diatoms</kwd><kwd>aquatic palynomorphs</kwd><kwd>dinocysts</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Арктика</kwd><kwd>море Лаптевых</kwd><kwd>трансгрессия</kwd><kwd>диатомовые водоросли</kwd><kwd>водные палиноморфы</kwd><kwd>диноцисты</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Svendsen J., Alexanderson H., Astakhov V. et al.
