Discrete bulk sediment properties data from Mercer Subglacial Lake

This dataset contains bulk sediment properties measurements from cores collected from Mercer Subglacial Lake by the SALSA project. Included are: physical properties (bulk density, mass water content, porosity, shear strength, particle size distribution, and mineralogy); carbon (inorganic and organic); iron (ascorbate- and dithionite-extractable); and sulfur (acid-volatile and chromium-reducible).本数据集包含由SALSA项目从默瑟冰下湖（Mercer Subglacial Lake）采集的岩芯的沉积物整体性质测量数据。所涵盖的测量内容包括：物理性质（容重、质量含水量、孔隙度、抗剪强度、粒径分布及矿物组成）；碳（无机碳与有机碳）；铁（抗坏血酸可提取态铁与连二亚硫酸盐可提取态铁）；以及硫（酸挥发性硫与铬还原态硫）。
