IODP Expedition 390 Scanning electron microscope images

Microscopic images of discrete samples were acquired using a scanning electron microscope (SEM) and captured as image files. These files were uploaded along with a brief description and a record of the microscopic conditions when the image was taken.本数据集包含通过扫描电子显微镜（Scanning Electron Microscope，SEM）采集的离散样本显微图像，此类图像均以图像文件形式存储，且所有文件均附带简要说明与拍摄时的显微条件记录。
