Counts were made at 500X, ignoring Chaetoceros spores and Thalassionema nitzschioides that dominate the sediment assemblages and mask subtle seasonal changes that occur in less...本次显微计数在500倍放大倍率下完成，统计过程未纳入在沉积物组合中占据优势、且会掩盖丰度较低类群所发生的细微季节变化的角毛藻孢子（Chaetoceros spores）与菱形海线藻（Thalassionema nitzschioides）。
