IODP Expedition 396 Whole-round core section composite 360 degree images

Images of the outside of hard rock whole-round sections were acquired using a linescan imager (Section Half Imaging Logger [SHIL]) and a special holder that allows each 90 degree segment of the outer surface to be positioned properly. The images were taken at a resolution of 20 lines/mm (50 micropixels). JRSO staff take these quadrant images and compile them into a side-by-side rollout photograph of the section. Composite images are available as both JPG and TIF image formats. Individual quadrant images are available as JPG images only through this report; contact the IODP-JRSO Data Librarian if quadrant TIF files (~160 MB) are needed.

本数据集采用线扫描成像仪（Section Half Imaging Logger，缩写SHIL）与专用定位夹具，采集硬岩完整岩心段的外壁图像；该夹具可确保外壁的每个90度扇形段均能实现精准定位。图像采集分辨率为20线/毫米（50微像素）。JRSO工作人员将采集得到的象限图像拼接为该岩心段的轴向展开拼接全景照片。合成全景图像提供JPG与TIF两种格式文件。本报告仅提供单幅象限图像的JPG格式文件；若需单幅约160MB的象限图像TIF格式文件，请联系IODP-JRSO数据馆员。
