Calcareous nannofossil fluxes from ODP Hole 115-707A during the past 15 million years

This dataset contains calcareous nannofossil flux data at ODP Site 707 during the past 15 million years. Samples were prepared using the drop technique (Bordiga et al., 2015; doi:10.1016/j.revmic.2015.05.002) and nannofossil abundance was determined under the polarized-light microscope. Fluxes were calculated from the absolute abundances and the site-specific mass accumulation rates (data from Suchéras-Marx and Henderiks (2014; doi:10.1016/j.gloplacha.2014.10.015)) with reproducibility of ±15%.

本数据集涵盖了过去1500万年间大洋钻探计划（Ocean Drilling Program，ODP）707站位的钙质超微化石通量数据。样本采用滴涂法（drop technique）制备（Bordiga等，2015；doi:10.1016/j.revmic.2015.05.002），并通过偏光显微镜（polarized-light microscope）测定钙质超微化石的丰度。通量由绝对丰度与站位特异性质量累积速率（数据源自Suchéras-Marx与Henderiks，2014；doi:10.1016/j.gloplacha.2014.10.015）计算得到，其重现性误差为±15%。
