9633501 Fryer The PIs study the relationship between the structure of South Marina forearc and sites of volcanism and fluid venting. Venting areas are accessible in the Mariana convergent plate system because its lacks an accretionary sediment wedge. The compilation of bathymetric and sonar imagery data will provide a basis from which to map seafloor structures. Seismic and MR1 survey will identify sites for detailed observations of fluid venting. Six channel seismic reflection data will be gathered during a month-long cruise.

9633501弗莱尔PI研究南岸弧前结构与火山活动和流体喷发地点之间的关系。在马里亚纳会聚板块系统中，喷发区是可到达的，因为它缺乏一个可吸积的沉积物楔形。水深测量和声纳图像数据的汇编将提供绘制海底结构图的基础。地震和MR1勘测将确定详细观察流体喷发的地点。在长达一个月的巡航期间，将收集六道地震反射数据。
