这项工作涉及在加利福尼亚州北部的巴贾附近进行一次短暂的巡航，在那里，中新世东太平洋隆起的侧翼包含了从隆起峰顶的起始和消亡的短期转换的绳索，以及板块运动变化对主要的、长期存在的转换的结构的伸展和挤压效应。SeaBeam 2000多波束声纳测深仪、单通道剖面仪和磁强计将是主要的调查工具。研究结果将适用于隆起-峰形分段演化的研究。
英文摘要
This work involves a short cruise off northern BajaCalifornia where the Miocene East Pacific Rise flank containsare cord of the orgin and demise of short transfrom offsets ofthe rise crest, and extensional and compressional effects of plate motion changes on the structure of major, long-lived tranforms. The Seabeam 2000 multibeam sonar sounder, a single-channel profiler, and a magetometer will be the principal survey tools. Results will be applicable to studies of the evolution of rise-crest segmentation.
