Outline of Final Research Achievements

In this study, vegetation dynamics influenced by the ocean and atmosphere changes were discussed based on pollen records from Japan Sea. Fossil pollen assemblages in the Japan Sea sediments were clarified by pollen analysis of the KR07-12 PC-07 core from Yamato Rise and the IODP Exp.346 U1427 core from the offshore of Tottori. Pollen records were compared with terrestrial pollen records around Lake Biwa and paleoenvironmental records from the Japan Sea sediments.
