The PI will make a series of heat flow measurements during a 30-day cruise in the sediments of the continental basement areas of the newly rifting Woodlark Basin to examine the evolution of extension from rift to conjugate margin stage. Thermal effects have not yet dissipated in this young margin. Heat flow values will provide constraints on temperature-dependent mechanical properties of the lithosphere during extension. Environmental and hydrothermal effects on the heat flow regime are considered to be small and swath bathymetry, sidescan imagery and gravity and magnetics data already exist.

PI将在为期30天的巡航期间在新裂谷的伍德拉克盆地的大陆基底地区的沉积物中进行一系列热流测量，以研究从裂谷阶段到共轭边缘阶段的伸展演化。在这块年轻的边际，热效应尚未消散。在伸展过程中，热流值将对岩石圈随温度变化的力学性质提供约束。环境和热液对热流状况的影响被认为是很小的，小水线面水深测量、侧扫图像以及重力和磁学数据已经存在。
