(Table T1) Relative abundance of selected radiolarian species from ODP Hole 199-1218A sediments

Sediment depth is given in mbsf. All radiolarians were counted under a light microscope with a magnification of 250x until the total exceeded 500. Note that relative abundances do not sum up to 100% per sample.沉积物深度以海底以下米（meters below seafloor, mbsf）为单位。所有放射虫（radiolarians）均在250倍放大倍率的光学显微镜下计数，直至总计数规模超过500个。请注意，单个样品的相对丰度总和未必等于100%。
