IODP Expedition 403 Section-half images

Digital section images were taken of the flat face of split cores on the Section Half Imaging Logger (SHIL) using a linescan camera at a resolution of 20 lines/mm (50 micron pixels). Cores were imaged as soon as possible after splitting to minimize color changes that occur through oxidation and drying. The SHIL produces TIF files as well as reduced-size JPG files. The TIF files are not kept online but users may request them from the IODP-JRSO Data Librarian.采用线扫描相机（linescan camera）在半岩心成像测井仪（Section Half Imaging Logger, SHIL）上对劈开岩心的平整端面进行数字截面成像，成像分辨率为20线/毫米（像素尺寸50微米）。为最大限度降低氧化与干燥过程中引发的颜色变化，岩心在被劈开后将尽快完成成像。该半岩心成像测井仪可生成TIF格式文件与压缩尺寸的JPG格式文件，其中TIF格式文件未进行在线存储，用户可向IODP-JRSO数据馆员提出申请获取。
