| Research Abstract |
Correlations among analytical values of sediments and meteorological observation data show that mean summer temperature and biogenic silica content have the highest correlation. Based on the transfer function between biogenic silica content and mean summer temperature, temperature difference between the warmest period and that of coldest is about 10 degrees Celcius. Based on REDFIT3.5, 16 periodicities of variation in biogenic silica content through the last 140 thousand years are recognized.
