Abstract:
Sediment core LV53-27 (41° 54′ N, 132° 33′ E) was retrieved in the northwestern Sea of Japan (Pervenets Seamount) at 1698 m depth during a joint Russian-Chinese expedition LV53 on RV "Akademik M.A. Lavrentyev" in 2010-11-10T23:39:00. Sediment core LV53-27 recovered about 120 kyr according to age model (Gorbarenko et al., 2023). 160 sediment samples, which were selected at an interval of 4 cm, were studied by the method of spore-pollen analysis. Pollen and spores species were identified with light microscope Mikmed-2. The table shows the pollen content of the main tree taxa, which was determined for each sample. The pollen content of each taxon was determined as the proportion of this taxon in a group of trees, while all trees were taken as 100%. The paleoclimatic coefficient, is named Tp, is calculated on the basis of spore-pollen analysis. The Tp was calculated using the formula Tp = 100×Twarm/(Twarm+Tcold), where Twarm is sum of tree temperate taxa and, Tcold is sum of tree boreal taxa. In this study temperate taxa are Quercus, Juglans, Ulmus, Carpinus, Tilia, Acer, Castanea, Cryptomeria.
