Surface sediments and sediment cores from the sea floor of Bowdoin Fjord, Greenland.

Surface sediments and sediment cores were collected from the sea floor with Ekman-Birge grab sampler and gravity corer, respectively. Grain size, mineral composition (XRD), lipids (biomarker), microfossils (e.g., palynomorph) and stratigraphic data will be analyzed from these sediments.表层沉积物与沉积岩芯分别通过埃克曼-伯奇采泥器（Ekman-Birge grab sampler）与重力柱状取样器（gravity corer）自海底采集得到。将对该批沉积物开展粒度、矿物组成（X射线衍射，XRD）、脂类（生物标志物biomarker）、微化石（例如孢粉类palynomorph）以及地层数据的分析测试。
