Supplementary Material to Katz, O., Almogi-Labin, A., Hyams-Kaphzan, O., 2025 (Marine Geology):
Stratigraphy and chronology of recent submarine mass transport along the continental slope of the southeastern Mediterranean Sea with applications to marine geohazard.

Figure S1. Density calibration for the studied cores; CT units (HU) to MKS bulk sediment-density (kg/m3). Twenty measurements of averaged HU values were performed in 1 cm by 6 cm vertical rectangles on a longitudinal CT slice in the middle of core AM113 (average HU of an individual rectangular ranged ~600 - ~1500). They were then plotted against the gamma density values obtained for the same core depths using a Multi Scan Core Logger (Haifa University, Israel).

Figure S2. Photographs of the studied cores. (a) AM113; (b) AM149; (c) AM015; (d) AM137. Depth scale is in centimeters. The major stratigraphic units and the transition from the Last Glacial Period to the Holocene are marked along each core. Also presented are the Munsell colors of the sediment at selected core depths.

Figure S3. The mode of the particle size distribution along the studied cores. The S1 sequence along each core, based on the TOC values (Figs. 4, 6, 8, 10), and the debrite sections along the cores (Figs. 2, 5, 7, 9) are marked by gray and reddish hatching, respectively. Selected Isochrones, based on radiocarbon dating and stratigraphy, are marked. (a) Core AM113; (b) Core AM149; (c) Core AM015; (d) Core AM137.

本材料为Katz O、Almogi-Labin A、Hyams-Kaphzan O于2025年发表于《Marine Geology》（海洋地质）论文的补充资料，原文主题为：地中海东南部大陆坡近期海底块状运移的地层学与年代学及其在海洋地质灾害研究中的应用。

图S1 研究岩芯的密度校准：CT单位（HU，Hounsfield Unit）转换为米-千克-秒制沉积物体密度（kg/m³）。在AM113号岩芯中部的纵向CT切片上，于1 cm×6 cm的垂直矩形区域内开展了20次平均HU值测量，单个矩形区域的平均HU值范围约为600~1500。将上述平均HU测量值与采用以色列海法大学Multi Scan Core Logger（多扫描岩芯测井仪）在对应岩芯深度获取的伽马密度值进行绘图校准。

图S2 研究岩芯实拍照片。(a) AM113号岩芯；(b) AM149号岩芯；(c) AM015号岩芯；(d) AM137号岩芯。深度标尺单位为厘米。各岩芯上均标注了主要地层单元以及末次冰期向全新世的过渡界面。同时还标注了选取岩芯深度处沉积物的门塞尔（Munsell）颜色。

图S3 研究岩芯的粒度分布模式。基于总有机碳（TOC，Total Organic Carbon）值得到的各岩芯S1序列（见图4、6、8、10）以及岩芯中的碎屑流沉积（debrite）段（见图2、5、7、9）分别以灰色和红色斜线标记。基于放射性碳定年与地层学得到的选定等时线亦进行了标注。(a) AM113号岩芯；(b) AM149号岩芯；(c) AM015号岩芯；(d) AM137号岩芯。
