Grain size analysis of IODP Site 303-U1307

This dataset consists of analyses of a Pliocene interval at Integrated Ocean Drilling Program (IODP) site 303-U1307. The site is located on Eirik Drift and was cored in 2004. The grain-size data consists of 51 samples measured in a Malvern-Panalytical Mastersizer 3000 particle-size analyzer equipped with a Hydro LV module. All data were generated in 2023. The timespan of the data set is from ~2.9 Ma to 3.2 Ma (~300 ka total duration), which covers the mid-Pliocene Warm Period (mPWP; 3.025-3.264 Ma) with an average sampling resolution of ~4 ka.

本数据集针对综合大洋钻探计划（Integrated Ocean Drilling Program, IODP）303-U1307站位的上新世地层段开展分析。该站位位于埃里克漂移体（Eirik Drift），并于2004年完成岩芯钻探。本数据集的粒度数据包含51个样品的测试结果，测试采用搭载Hydro LV湿法进样模块的马尔文帕纳科（Malvern-Panalytical）Mastersizer 3000激光粒度分析仪完成。所有测试数据均生成于2023年。本数据集的时间跨度约为2.9 Ma至3.2 Ma（总持续时长约300 ka），覆盖了上新世中期暖期（mid-Pliocene Warm Period, mPWP；3.025~3.264 Ma），平均采样分辨率约为4 ka。
