IODP Expedition 342 Visual core description

Descriptions of samples, generally at the section half and smear slide or thin section scale, were performed by shipboard scientists and recorded in the JRSO description software. Descriptive data for both macroscopic and microscopic examination were collected in a Microscoft Excel workbook by hole. A zip file of the entire expedition's observations is also available.

样品描述工作通常以岩芯半段（section half）、涂片（smear slide）或薄片（thin section）为分析尺度开展，由船上科考队员完成，并通过JRSO描述软件进行记录。宏观与微观检验的描述性数据按钻孔分类收集，并录入Microsoft Excel工作簿中。本次科考航次所有观测资料的ZIP压缩包同样可供获取。
