The focus of this project is the East Lau Spreading Center, a 390 km-long first-order ridge segment in the Lau backarc basin. This spreading center has been selected to be an integrated studies site by the Ridge 2000 program. This project will provide nested sidescan and hydrothermal surveys of the spreading center using a hull-mounted bathymetric and side-scan system, a 30 kHz sonar, and a 120 kHz sonar. The goal is to provide information on the spatial and temporal variations in crustal architecture, detect hydrothermal plumes and map variations in hydrothermal characteristics.

该项目的重点是东刘扩张中心，一个长390公里的一级山脊段，位于刘弧后盆地。这个传播中心已被Ridge 2000计划选为综合研究地点。该项目将使用船体安装的测深和侧扫系统、30千赫的声纳和120千赫的声纳，提供扩展中心的嵌套侧扫和热液调查。其目标是提供有关地壳结构的时空变化的信息，探测热液羽流并绘制热液特征的变化图。
