国际海洋发现计划（IODP）远征368 X是构成南中国海裂谷边缘计划的三次巡航中的第三次。第367、368和368 X号考察队有着共同的关键目标，即检验南海北方边缘断裂的科学假设，并将其裂谷样式和历史与其他非火山或岩浆贫乏的裂谷边缘进行比较。为整个计划选择了四个主要地点：一个在外缘高（OMH），三个在OMH向海的不同的边缘平行的基底脊上，从北到南非正式地标记了脊A、B和C。海脊位于从大洋中脊到南海稳定状态洋壳（C脊）的大陆-海洋过渡带（COT）。此外，主要针对构造和基底目标的钻探地点的沉积物岩心将提供关于东南亚边缘新生代区域环境发展的信息。
International Ocean Discovery Program (IODP) Expedition 368X is the third of three cruises that form the South China Sea Rifted Margin program. Expeditions 367, 368, and 368X share the common key objectives of testing scientific hypotheses of breakup of the northern South China Sea (SCS) margin and comparing its rifting style and history to other nonvolcanic or magma-poor rifted margins. Four primary sites were selected for the overall program: one in the outer margin high (OMH) and three seaward of the OMH on distinct, margin-parallel basement ridges informally la-beled Ridges A, B, and C from north to south. The ridges are located in the continent–ocean transition (COT) zone ranging from the OMH to the interpreted steady-state oceanic crust (Ridge C) of the SCS. The main scientific objectives include In addition, sediment cores from the drill sites targeting primarily tectonic and basement objectives will provide information on the Cenozoic regional environmental development of the Southeast Asia margin.Expedition 368X a started after
