| Research Abstract |
Antarctic region shows dry climate during the little ice age. After that, climate changed to relative wet condition in this area. In the coastal area of the Sea of Okhotsk in the east part of Hokkaido located to for subarctic zone, distinguished paleoenvironmental changes are not observed except for anthropogenic environment change. The closure or reduction of lake mouth is observed in Lake Tofutsu. This is suggest the slightly fall of sea level. In the coastal area of the Japan Sea located to for temperate zone, the flood sediments are observed around the end of little ice age (AD1600-1800). After that, anthropogenic environment changes are distinguished in this area.
