Data files present information on the quantitative distribution of the polycystine radiolarian species in the Quaternary marine sediments from the subarctic areas. Dataset on the open North Atlantic north of 43 °N contains percentages of 35 abundant (> 1%) species in 145 samples of five sediment cores. Dataset on the Sea of Okhotsk contains percentages of 31 abundant (> 1%) species in 794 samples of seven sediment cores. Dataset on the bottom surface sediments of the North Atlantic contains percentages of 35 abundant (> 1%) species in 78 grab and core-top samples. For the microscopic radiolarian analysis, the sediment fraction of > 40/50 μm was used.
数据文件展示了北极地区第四纪海洋沉积物中多囊放射虫物种的定量分布信息。北纬43°以北开阔北大西洋的数据集包含了来自5个沉积岩芯的145个样本中35种丰富(>1%)物种的百分比。鄂霍次克海的数据集包含了来自7个沉积岩芯的794个样本中31种丰富(>1%)物种的百分比。北大西洋海底表面沉积物的数据集包含了来自78个抓斗样本和岩芯顶部样本中35种丰富(>1%)物种的百分比。对于微观放射虫分析,使用了大于40/50μm的沉积物部分。
