摘要: Diatom fossils from core sediments and living diatoms water samples of Notoro Lagoon in northern Japan were examined to evaluate natural climate effects on lagoon environmental changes. In 1974, the artificial inlet was excavated. Immediately after, anoxic bottom began disappear due an increasing exchange rate. However, chemical oxygen demand (COD) gradually increased, with fluctuations, during last 30 years. addition, dominant diatom assemblages shifted ice-related spring bloom taxa after excavation. The each year sediment also strongly related timing ice melting. This is because COD affected by deposited volume blooming diatoms, which controlled duration cover discharge Okhotsk Sea likely air pressure pattern change over North Pacific like Decadal Oscillation (PDO).
